Vaccines

Unlike previous studies focused on vaccine effectiveness (VE) in ambulatory care office visits, Angela P. Campbell, MD, MPH, and associates have uncovered evidence of the overall benefit influenza vaccines play in reducing hospitalizations and emergency department visits in pediatric influenza patients.

“Our data provide important VE estimates against severe influenza in children,” the researchers noted in Pediatrics, adding that the findings “provide important evidence supporting the annual recommendation that all children 6 months and older should receive influenza vaccination.”

Dr. Campbell and colleagues collected ongoing surveillance data from the New Vaccine Surveillance Network (NVSN), which is a network of pediatric hospitals across seven cities, including Kansas City, Mo.; Rochester, N.Y.; Cincinnati; Pittsburgh; Nashville, Tenn.; Houston; and Seattle. The influenza season encompassed the period Nov. 7, 2018 to June 21, 2019.

A total of 2,748 hospitalized children and 2,676 children who had completed ED visits that did not lead to hospitalization were included. Once those under 6 months were excluded, 1,792 hospitalized children were included in the VE analysis; of these, 226 (13%) tested positive for influenza infection, including 211 (93%) with influenza A viruses and 15 (7%) with influenza B viruses. Fully 1,611 of the patients (90%), had verified vaccine status, while 181 (10%) had solely parental reported vaccine status. The researchers reported 88 (5%) of the patients received mechanical ventilation and 7 (<1%) died.

Most noteworthy, the researchers observed a significant reduction in laboratory-confirmed hospitalizations by 41% in children vaccinated against the flu. They further estimated a significant reduction in hospitalizations linked to A(H3N2) and A(H1N1)pdm09 viruses, even in the presence of circulating A(H3N2) viruses that differed from the A(H3N2) vaccine component.

Studies from other countries during the same time period showed that while “significant protection against influenza-associated ambulatory care visits and hospitalizations among children infected with A(H1N1)pdm09 viruses” was observed, the same could not be said for protection against A(H3N2) viruses, which varied among pediatric outpatients in the United States (24%), in England (17% outpatient; 31% inpatient), Europe (46%), and Canada (48%). They explained that such variation in vaccine protection is multifactorial, and includes virus-, host-, and environment-related factors. They also noted that regional variations in circulating viruses, host factors including age, imprinting, and previous vaccination could explain the study’s finding of vaccine protection against both A(H1N1)pdm09 and A(H3N2) viruses.

When comparing VE estimates between ED visits and hospitalizations, the researchers observed one significant difference, that “hospitalized children likely represent more medically complex patients, with 58% having underlying medical conditions and 38% reporting at lease one hospitalization in the past year, compared with 28% and 14% respectively, among ED participants.”

Strengths of the study included the prospective multisite enrollment that provided data across diverse locations and representation from pediatric hospitalizations and ED care, which were not previously strongly represented in the literature. The single-season study with small sample size was considered a limitation, as was the inability to evaluate full and partial vaccine status. Vaccine data also were limited for many of the ED patients observed.

Dr. Campbell and colleagues did caution that while they consider their test-negative design optimal for evaluating both hospitalized and ED patients, they feel their results should not be “interpreted as VE against influenza-associated ambulatory care visits or infections that are not medically attended.”

In a separate interview, Michael E. Pichichero, MD, director of the Rochester General Hospital Research Institute and a clinical professor of pediatrics at the University of Rochester (N.Y.), observed: “There are really no surprises here. A well done contemporary study confirms again the benefits of annual influenza vaccinations for children. Viral coinfections involving SARS-CoV-2 and influenza have been reported from Australia to cause heightened illnesses. That observation provides further impetus for parents to have their children receive influenza vaccinations.”

The researchers cited multiple sources of financial support for their ongoing work, including Sanofi, Quidel, Moderna, Karius, GlaxoSmithKline, Merck, AstraZeneca, and Pfizer. Funding for this study was supported by the Centers for Disease Control and Prevention. Dr. Pichichero said he had no relevant financial disclosures.

Rates of human papillomavirus vaccination increased for both boys and girls in the United States over the past decade, but remain below target levels and vary widely across states based on data from a nested cohort study including more than 7 million children.

“Understanding regional and temporal variations in HPV vaccination coverage may help improve HPV vaccination uptake by informing public health policy,” Szu-Ta Chen, MD, of Harvard University, Boston, and colleagues wrote in Pediatrics.

To identify trends in one-dose and two-dose human papillomavirus (HPV) vaccination coverage, the researchers reviewed data from the MarketScan health care database between January 2003 and December 2017 that included 7,837,480 children and 19,843,737 person-years. The children were followed starting at age 9, when HPV vaccination could begin, and ending at one of the following: the first or second vaccination, insurance disenrollment, December 2017, or the end of the year in which they turned 17.

Overall, the proportion of 15-year-old girls and boys with at least a one-dose HPV vaccination increased from 38% and 5%, respectively, in 2011 to 57% and 51%, respectively, in 2017. The comparable proportions of girls and boys with at least a two-dose vaccination increased from 30% and 2%, respectively, in 2011 to 46% and 39%, respectively, in 2017.

Coverage lacks consistency across states

However, the vaccination coverage varied widely across states; two-dose HPV vaccination coverage ranged from 80% of girls in the District of Columbia to 15% of boys in Mississippi. In general, states with more HPV vaccine interventions had higher levels of vaccination, the researchers noted.

Legislation to improve vaccination education showed the strongest association with coverage; an 8.8% increase in coverage for girls and an 8.7% increase for boys. Pediatrician availability also was a factor associated with a 1.1% increase in coverage estimated for every pediatrician per 10,000 children.

Cumulative HPV vaccinations seen among children continuously enrolled in the study were similar to the primary analysis, the Dr. Chen and associates said. “After the initial HPV vaccination, 87% of girls and 82% of boys received a second dose by age 17 in the most recent cohorts.”

However, the HPV vaccination coverage remains below the Healthy People 2020 goal of 80% of children vaccinated by age 15 years, the researchers said. Barriers to vaccination may include a lack of routine clinical encounters in adolescents aged 11-17 years. HPV vaccination coverage was higher in urban populations, compared with rural, which may be related to a lack of providers in rural areas.

“Thus, measures beyond recommending routine vaccination at annual check-ups might be necessary to attain sufficient HPV vaccine coverage, and the optimal strategy may differ by state characteristics,” they wrote.

The study findings were limited by several factors including the use of data from only commercially-insured children and lack of data on vaccines received outside of insurance, the researchers noted.

However, the results were strengthened by the large, population-based sample, and support the need for increased efforts in HPV vaccination. “Most states will not achieve the Healthy People 2020 goal of 80% coverage with at least two HPV vaccine doses by 2020,” Dr. Chen and associates concluded.

Vaccination goals are possible with effort in the right places

The fact of below-target vaccination for HPV in the United States may be old news, but the current study offers new insights on HPV uptake, Amanda F. Dempsey, MD, PhD, of the University of Colorado at Denver, in Aurora, wrote in an accompanying editorial.

“A unique feature of this study is the ability of its researchers to study individuals over time, particularly at a national scope,” which yielded two key messages, she said.

The longitudinal examination of vaccination levels among birth cohorts showed that similar vaccination levels were achieved more quickly each year.

“For example, among the birth cohort from the year 2000, representing 17-year-olds at the time data were abstracted for the study, 40% vaccination coverage was achieved when this group was 14 years old. In contrast, among the birth cohort from the year 2005, representing 12-year-olds at the time of data abstraction, 40% vaccination coverage was reached at the age of 12,” Dr. Dempsey explained.

In addition, the study design allowed the researchers to model future vaccine coverage based on current trends, said Dr. Dempsey. “The authors estimate that, by the year 2022, the 2012 birth cohort will have reached 80% coverage for the first dose in the HPV vaccine series.”

Dr. Dempsey said she was surprised that the models did not support the hypothesis that school mandates for vaccination would increase coverage; however, there were few states in this category.

Although the findings were limited by the lack of data on uninsured children and those insured by Medicaid, the state-by-state results show that the achievement of national vaccination goals is possible, Dr. Dempsey said. In addition, the findings “warrant close consideration by policy makers and the medical community at large regarding vaccination policies and workforce,” she emphasized.The study received no outside funding. Dr. Chen had no financial conflicts to disclose. Several coauthors reported research grants to their institutions from pharmaceutical companies or being consultants to such companies. Dr. Dempsey disclosed serving on the advisory boards for Merck, Pfizer, and Sanofi Pasteur.

The 2020-2021 influenza season is shaping up to be challenging. Its likely concurrence with the ongoing severe acute respiratory syndrome-coronavirus 2 (­SARS-coV-2) pandemic (COVID-19) will pose diagnostic and therapeutic dilemmas and could overload the hospital system. But there could also be potential synergies in preventing morbidity and mortality from each disease.

A consistent pattern overthe past few influenza seasons

During the 2019-2020 flu season, there were an estimated 410,000 to 740,000 hospitalizations and 24,000 to 62,000 deaths attributed to influenza.¹ As seen in FIGURE 1, office visits for influenza-like illness (ILI) began to increase in late November and early December in each of the last 3 years (2017-2018, 2018-2019, ­2019-2020) and stayed elevated above baseline for about 4 months each season.¹

The effectiveness of influenza vaccine during the 2019-2020 season is being estimated using the US Flu Vaccine Effectiveness Network, which has close to 9000 enrollees. Overall, it appears the vaccine was 39% effective against medically attended influenza, with a higher effectiveness against influenza B (44%) than against A/H1N1 (31%). Effectiveness against influenza B was similar in all age groups, but effectiveness against A/H1N1 was highest for those ages 50 to 64 years (45%) and lowest for those ages 6 months through 8 years (22%), although 95% confidence intervals overlapped for all age groups (FIGURE 2). These preliminary effectiveness rates were presented at the summer meeting of the Advisory Committee on Immunization Practices (ACIP).¹

Influenza vaccine safety data for ­2019-2020 were based on the Vaccine Adverse Event Reporting System (VAERS), a passive surveillance system, and on the Vaccine Safety Datalink (VSD) system, an active surveillance system involving close to 6 million doses administered at VSD sites. No safety concerns were identified for any of the different vaccine types. Both the VAERS and VSD surveillance systems have been described in more detail in a previous Practice Alert.²

Recommendations for 2020-2021

The composition of the influenza vaccines for this year’s flu season will be different for 3 of the 4 antigens: A/H1N1, A/H2N2 and B/Victoria.³ The antigens included in the influenza vaccines each year are decided on in the spring, based on surveillance of circulating strains around the world. The effectiveness of the vaccine each year largely depends on how well the strains included in the vaccine match those circulating in the United States during the influenza season.

The main immunization recommendation for preventing morbidity and mortality from influenza has not changed: All individuals ages 6 months and older without a contraindication should receive an influenza vaccine.⁴ The Centers for Disease Control and Prevention (CDC) recommends that patients receive the vaccine by the end of October.⁴ This includes the second dose for those children younger than 9 years who need 2 doses—ie, those who have received fewer than 2 doses of influenza vaccine prior to July 2020. Vaccination should continue through the end of the season for anyone who has not received a 2020-2021 influenza vaccine.

Two new influenza vaccine products are available for use in those ages 65 years and older: Fluzone high-dose quadrivalent and Fluad Quadrivalent (adjuvanted).⁴ Both of these products were available last year as trivalent options. Currently no specific vaccine product is listed as preferred by ACIP for those ages 65 and older.

Continue to: New vaccine contraindications

New vaccine contraindications. Four medical conditions have been added to the list of contraindications for quadrivalent live, attenuated influenza vaccine (LAIV4): cochlear implant, cerebrospinal fluid leak, asplenia (anatomic and functional), and sickle cell anemia.⁴ In addition, those who receive LAIV4 should not be prescribed an influenza antiviral until 2 weeks after receiving the vaccine. And the vaccine should not be administered for 48 hours after receipt of oseltamivir or zanamivir, 5 days after peramivir, and 17 days after baloxavir marboxil.⁴ This is to prevent possible antiviral inactivation of the live attenuated influenza viruses in the ­vaccine.

For those who have a history of severe allergic reaction to eggs, there are now 2 egg-free options: cell-culture-based inactivated vaccine (ccIIV4) and recombinant influenza vaccine (RIV4).^3,4 Urticaria alone is not considered a severe reaction. If neither of these egg-free options is available, a vaccine may still be administered in a medical setting supervised by a provider who is able to manage a severe allergic reaction (which rarely occurs).

All vaccine products available for the upcoming influenza season are listed and described on the CDC Web site, as is a summary of related recommendations.⁴ Particular attention should be paid to the dose of vaccine administered, as it differs by product for those ages 6 through 35 months of age and those ages 65 years and older.

Use of antiviral medications

Four antiviral medications are now available for treating influenza (3 neuraminidase inhibitors and 1 endonuclease inhibitor), and there are 2 agents for preventing influenza, both neuraminidase inhibitors (TABLE 1).⁵ The CDC recommends treating with antivirals as soon as possible if individuals with confirmed or suspected influenza require hospitalization; have severe, complicated, or progressive illness; or are at high risk for complications. Use antivirals based on clinical judgment if previously healthy individuals do not have severe complications and are not at increased risk for complications, and only if the medication can be started within 48 hours of symptom onset.

The CDC discourages widespread use of antivirals to prevent influenza, either pre- or postexposure, although it specifies certain situations in which usage would be acceptable (TABLE 2).⁵ There is some concern that widespread use could lead to the emergence of drug-resistant strains and that using postexposure dosing could lead to suboptimal treatment if influenza infection occurred before the start of prophylaxis. If postexposure antivirals are prescribed, they should be started within 48 hours of exposure and continued for 7 days after the last exposure.

A potential perfect storm: Concurrence of influenza and SARS-coV-19

While we have vaccines and antivirals to prevent influenza, and have effective antivirals for treatment, no prevention or treatment options exist for COVID-19, except, possibly, dexamethasone to reduce mortality among those seriously ill.⁶ The concurrence of influenza and COVID-19 will present unique challenges for the health care system.

Action steps. Keep abreast of the incidences of circulating SARS-coV-19 and influenza viruses in your community. The similar signs and symptoms of these 2 infectious agents will complicate diagnosis. Rapid, or point-of-care, tests for influenza are widely available, but their accuracy varies and not all tests detect both influenza A and B. The CDC lists approved point-of-care tests at www.cdc.gov/flu/professionals/diagnosis/table-ridt.html and advises on how to interpret these test results when influenza is and is not circulating in the community, at www.cdc.gov/flu/­professionals/diagnosis/clinician_­guidance_ridt.htm.

Clinical practice advice for both conditions should be implemented when any patient presents with ILI:⁷

• Most patients who are not seriously ill and have no conditions that place them at high risk for adverse outcomes can be treated symptomatically at home.
• Those with ILI should be tested for both influenza virus and SARS-CoV-2 if testing is available. It is possible to be co-infected.
• Sick patients should self-isolate at home for the duration of their symptoms.
• If others live in the house, the sick person should stay in a separate room and wear a mask. Everyone in the house should cover coughs and sneezes (if not wearing a mask), dispose of used tissues in a trash can (rather than leaving them on night stands and countertops), and wash hands frequently.
• All household members should be vaccinated against influenza. Those who are unvaccinated, and those at high risk who have been recently vaccinated, can consider influenza antiviral prophylaxis. If the sick family member is confirmed to have COVID-19, with no co-existing influenza, anti-influenza antiviral prophylaxis may be discontinued.
• Clinical infection control practices should be the same for anyone presenting with ILI.⁷ Enhanced clinic-based infection control practices to prevent spread of SARS-CoV-2 are listed in TABLE 3.⁸

Since there currently are no preventive medications proven to work for COVID-19, the main clinical decision physicians will have to make when a patient presents with ILI is whether to use antivirals to treat those who are at risk for complications based on the result of rapid, on-site influenza testing, or clinical presentation, or both. In this situation, knowledge of which viruses are circulating at high rates in the community could be valuable.

Milder season or perfect storm? The society-wide interventions that have been encouraged (although not mandated everywhere) to prevent community spread of ­SARS-CoV-2 should help prevent the community spread of influenza as well, and, if adhered to, may lead to a milder influenza season than would otherwise have occurred. However, given the uncertainties, the combination of influenza and coronavirus could present a perfect storm for the health care system and result in higher-than-normal morbidity and mortality from ILI and pneumonia overall.

Continue to: The possibility that one or more vaccines...

The possibility that one or more vaccines to prevent COVID-19 may be available in late 2020 or early 2021 offers hope. However, in current testing, the vaccine is not being given simultaneously with the influenza vaccine. If the potential for adverse interaction exists between the vaccines, it is important that influenza vaccine be given by mid- to late-October to avoid such an interaction if and when the new SARS-CoV-2 vaccine becomes available. Individuals who have symptoms of COVID-19 should not be vaccinated with influenza vaccine until they are considered noninfectious.

Encourage influenza vaccination. The COVID-19 pandemic may make it difficult to achieve desired community influenza vaccine levels because of decreased visits to medical facilities for preventive care, possible lower insurance coverage due to loss of employment, and a decrease in worksite mass vaccination programs. This makes it important for family physicians to encourage and offer influenza vaccines at their clinical sites.

Several evidence-based practices have been shown to improve vaccine uptake. Examples of such practices include patient reminder and recall systems that provide feedback to clinicians about rates of vaccination among patients, and establishing standing orders for vaccine administration that allow other health care providers to assess a patient’s immunization status and administer vaccinations according to a protocol.⁹ Finally, the CDC provides a video on how to recommend influenza vaccine to those who may be resistant (www.cdc.gov/vaccines/howirecommend/adult-vacc-videos.html).

The 2020-2021 influenza season is shaping up to be challenging. Its likely concurrence with the ongoing severe acute respiratory syndrome-coronavirus 2 (­SARS-coV-2) pandemic (COVID-19) will pose diagnostic and therapeutic dilemmas and could overload the hospital system. But there could also be potential synergies in preventing morbidity and mortality from each disease.

A consistent pattern overthe past few influenza seasons

During the 2019-2020 flu season, there were an estimated 410,000 to 740,000 hospitalizations and 24,000 to 62,000 deaths attributed to influenza.¹ As seen in FIGURE 1, office visits for influenza-like illness (ILI) began to increase in late November and early December in each of the last 3 years (2017-2018, 2018-2019, ­2019-2020) and stayed elevated above baseline for about 4 months each season.¹

The effectiveness of influenza vaccine during the 2019-2020 season is being estimated using the US Flu Vaccine Effectiveness Network, which has close to 9000 enrollees. Overall, it appears the vaccine was 39% effective against medically attended influenza, with a higher effectiveness against influenza B (44%) than against A/H1N1 (31%). Effectiveness against influenza B was similar in all age groups, but effectiveness against A/H1N1 was highest for those ages 50 to 64 years (45%) and lowest for those ages 6 months through 8 years (22%), although 95% confidence intervals overlapped for all age groups (FIGURE 2). These preliminary effectiveness rates were presented at the summer meeting of the Advisory Committee on Immunization Practices (ACIP).¹

Influenza vaccine safety data for ­2019-2020 were based on the Vaccine Adverse Event Reporting System (VAERS), a passive surveillance system, and on the Vaccine Safety Datalink (VSD) system, an active surveillance system involving close to 6 million doses administered at VSD sites. No safety concerns were identified for any of the different vaccine types. Both the VAERS and VSD surveillance systems have been described in more detail in a previous Practice Alert.²

Recommendations for 2020-2021

The composition of the influenza vaccines for this year’s flu season will be different for 3 of the 4 antigens: A/H1N1, A/H2N2 and B/Victoria.³ The antigens included in the influenza vaccines each year are decided on in the spring, based on surveillance of circulating strains around the world. The effectiveness of the vaccine each year largely depends on how well the strains included in the vaccine match those circulating in the United States during the influenza season.

The main immunization recommendation for preventing morbidity and mortality from influenza has not changed: All individuals ages 6 months and older without a contraindication should receive an influenza vaccine.⁴ The Centers for Disease Control and Prevention (CDC) recommends that patients receive the vaccine by the end of October.⁴ This includes the second dose for those children younger than 9 years who need 2 doses—ie, those who have received fewer than 2 doses of influenza vaccine prior to July 2020. Vaccination should continue through the end of the season for anyone who has not received a 2020-2021 influenza vaccine.

Two new influenza vaccine products are available for use in those ages 65 years and older: Fluzone high-dose quadrivalent and Fluad Quadrivalent (adjuvanted).⁴ Both of these products were available last year as trivalent options. Currently no specific vaccine product is listed as preferred by ACIP for those ages 65 and older.

“I worry that vaccines are going to be sold like magic powder that we sprinkle across the land and make the virus go away,” Paul Offit, MD, said at the virtual American Academy of Pediatrics (AAP) 2020 National Conference. “That’s not true.”

Even after effective vaccines for SARS-CoV-2 are in widespread use, wearing masks will still be advisable to prevent COVID-19, according to Dr. Offit, director of the Vaccine Education Center and an attending physician in the Division of Infectious Diseases at Children’s Hospital of Philadelphia.

“I think we can get a vaccine that’s 75%-80% effective at preventing mild to moderate disease, but that means one of every four people can still get moderate to severe disease,” Dr. Offit continued.

And that’s if there is high uptake of the vaccine, which may not be the case. Recent polls have suggested there is considerable concern about the pending vaccines.

“It’s somewhat understandable,” Dr. Offitt acknowledged, especially given the “frightening” language used to describe vaccine development. Terms such as “warp speed” may suggest that haste might trump safety considerations. Before COVID-19, the fastest vaccine ever developed was for mumps, he said, with the virus isolated in 1963 and a commercial product available in 1967.
 

Addressing hesitancy in clinics

In a wide-ranging livestream plenary presentation, Dr. Offit, coinventor of a rotavirus vaccine, shed light on SARS-CoV-2 vaccine development and his impressions of vaccine hesitancy among patients and families. He also offered advice for how to reassure those skeptical of the safety and efficacy of any SARS-COV-2 vaccine, given the accelerated development process.

With more than 180 different vaccines in various stages of investigation, Dr. Offit called the effort to develop COVID-19 vaccines “unprecedented.” Part of that is a result of governments relieving pharmaceutical companies of much of the typical financial risk – which often climbs to hundreds of millions of dollars – by underwriting the costs of vaccine development to battle the pandemic-inducing virus, he said.

But this very swiftness is also stoking antivaccine sentiment. Dr. Offit, part of vaccine advisory groups for the National Institutes of Health and U.S. Food and Drug Administration, cited recent research reporting nearly half of American adults definitely or probably would not get a COVID-19 vaccine if it were available today.

“One way you convince skeptics is with data presented in a clear, compassionate, and compelling way,” he said.

“The other group is vaccine cynics, who are basically conspiracy theorists who believe pharmaceutical companies control the world, the government, the medical establishment. I think there’s no talking them down from this.”

Numerous strategies are being used in COVID-19 vaccine development, he noted, including messenger RNA, DNA, viral vectors, purified protein, and whole killed virus. Dr. Offit believes any candidates approved for distribution will likely be in the range of 75% effective at preventing mild to moderate symptoms.

But clinicians should be ready to face immediate questions of safety. “Even if this vaccination is given to 20,000 [trial participants] safely, that’s not 20 million,” Dr. Offit said. “Anyone could reasonably ask questions about if it causes rare, serious side effects.

“The good news is, there are systems in place,” such as adverse event reporting systems, to identify rare events, even those that occur in one in a million vaccine recipients. Reminding patients of that continued surveillance can be reassuring.

Another reassuring point is that COVID-19 vaccine trial participants have included people from many diverse populations, he said. But children, notably absent so far, should be added to trials immediately, Dr. Offit contends.

“This is going to be important when you consider strategies to get children universally back into school,” he said, which is a “critical issue” from both learning and wellness standpoints. “It breaks my heart that we’ve been unable to do this when other countries have.”
 

Transparency will be paramount

While presenting data transparently to patients is key in helping them accept COVID-19 vaccination, Dr. Offit said, he also believes “telling stories” can be just as effective, if not more so. When the varicella vaccine was approved in 1995, he said, the “uptake the first few years was pretty miserable” until public service messaging emphasized that some children die from chickenpox.

“Fear works,” he said. “You always worry about pushback of something being oversold, but hopefully we’re scared enough about this virus” to convince people that vaccination is wise. “I do think personal stories carry weight on both sides,” Dr. Offit said.

Mark Sawyer, MD, of University of California San Diego School of Medicine and Rady Children’s Hospital in San Diego, California, said Offit’s presentation offered important takeaways for clinicians about how to broach the topic of COVID-19 vaccination with patients and families.

“We need to communicate clearly and transparently to patients about what we do and don’t know” about the vaccines, Dr. Sawyer said in an interview. “We will know if they have common side effects, but we will not know about very rare side effects until we have used the vaccines for a while.

“We will know how well the vaccine works over the short-term, but we won’t know over the long term,” added Dr. Sawyer, a member of the AAP Committee on Infectious Diseases.

“We can reassure the community that SARS-CoV-2 vaccines are being evaluated in trials in the same way and with the same thoroughness as other vaccines have been,” he said. “That should give people confidence that shortcuts are not being taken with regard to safety and effectiveness evaluations.”

Dr. Offit and Dr. Sawyer have disclosed no relevant financial relationships.

Before COVID-19, the fastest vaccine ever developed was for mumps, he said, with the virus isolated in 1963 and a commercial product available in 1967.
 

Addressing hesitancy in clinics

In a wide-ranging livestream plenary presentation, Dr. Offit, coinventor of a rotavirus vaccine, shed light on SARS-CoV-2 vaccine development and his impressions of vaccine hesitancy among patients and families. He also offered advice for how to reassure those skeptical of the safety and efficacy of any SARS-COV-2 vaccine, given the accelerated development process.

With more than 180 different vaccines in various stages of investigation, Dr. Offit called the effort to develop COVID-19 vaccines “unprecedented.” Part of that is a result of governments relieving pharmaceutical companies of much of the typical financial risk – which often climbs to hundreds of millions of dollars – by underwriting the costs of vaccine development to battle the pandemic-inducing virus, he said.

But this very swiftness is also stoking antivaccine sentiment. Dr. Offit, part of vaccine advisory groups for the National Institutes of Health and U.S. Food and Drug Administration, cited recent research reporting nearly half of American adults definitely or probably would not get a COVID-19 vaccine if it were available today.

“One way you convince skeptics is with data presented in a clear, compassionate, and compelling way,” he said.

“The other group is vaccine cynics, who are basically conspiracy theorists who believe pharmaceutical companies control the world, the government, the medical establishment. I think there’s no talking them down from this.”

Numerous strategies are being used in COVID-19 vaccine development, he noted, including messenger RNA, DNA, viral vectors, purified protein, and whole killed virus. Dr. Offit believes any candidates approved for distribution will likely be in the range of 75% effective at preventing mild to moderate symptoms.

But clinicians should be ready to face immediate questions of safety. “Even if this vaccination is given to 20,000 [trial participants] safely, that’s not 20 million,” Dr. Offit said. “Anyone could reasonably ask questions about if it causes rare, serious side effects.

“The good news is, there are systems in place,” such as adverse event reporting systems, to identify rare events, even those that occur in one in a million vaccine recipients. Reminding patients of that continued surveillance can be reassuring.

Another reassuring point is that COVID-19 vaccine trial participants have included people from many diverse populations, he said. But children, notably absent so far, should be added to trials immediately, Dr. Offit contends.

“This is going to be important when you consider strategies to get children universally back into school,” he said, which is a “critical issue” from both learning and wellness standpoints. “It breaks my heart that we’ve been unable to do this when other countries have.”
 

Transparency will be paramount

While presenting data transparently to patients is key in helping them accept COVID-19 vaccination, Dr. Offit said, he also believes “telling stories” can be just as effective, if not more so. When the varicella vaccine was approved in 1995, he said, the “uptake the first few years was pretty miserable” until public service messaging emphasized that some children die from chickenpox.

“Fear works,” he said. “You always worry about pushback of something being oversold, but hopefully we’re scared enough about this virus” to convince people that vaccination is wise. “I do think personal stories carry weight on both sides,” Dr. Offit said.

Mark Sawyer, MD, of University of California San Diego School of Medicine and Rady Children’s Hospital in San Diego, California, said Offit’s presentation offered important takeaways for clinicians about how to broach the topic of COVID-19 vaccination with patients and families.

“We need to communicate clearly and transparently to patients about what we do and don’t know” about the vaccines, Dr. Sawyer said in an interview. “We will know if they have common side effects, but we will not know about very rare side effects until we have used the vaccines for a while.

“We will know how well the vaccine works over the short-term, but we won’t know over the long term,” added Dr. Sawyer, a member of the AAP Committee on Infectious Diseases.

“We can reassure the community that SARS-CoV-2 vaccines are being evaluated in trials in the same way and with the same thoroughness as other vaccines have been,” he said. “That should give people confidence that shortcuts are not being taken with regard to safety and effectiveness evaluations.”

Dr. Offit and Dr. Sawyer have disclosed no relevant financial relationships.

“I worry that vaccines are going to be sold like magic powder that we sprinkle across the land and make the virus go away,” Paul Offit, MD, said at the virtual American Academy of Pediatrics (AAP) 2020 National Conference. “That’s not true.”

Even after effective vaccines for SARS-CoV-2 are in widespread use, wearing masks will still be advisable to prevent COVID-19, according to Dr. Offit, director of the Vaccine Education Center and an attending physician in the Division of Infectious Diseases at Children’s Hospital of Philadelphia.

“I think we can get a vaccine that’s 75%-80% effective at preventing mild to moderate disease, but that means one of every four people can still get moderate to severe disease,” Dr. Offit continued.

And that’s if there is high uptake of the vaccine, which may not be the case. Recent polls have suggested there is considerable concern about the pending vaccines.

“It’s somewhat understandable,” Dr. Offitt acknowledged, especially given the “frightening” language used to describe vaccine development. Terms such as “warp speed” may suggest that haste might trump safety considerations.

Parents who did not vaccinate their children against influenza last year were significantly less likely to do so this year than parents whose children were vaccinated last year, based on survey data from more than 2,000 parents with babies and young children.

“Pediatric vaccination will be an important component to mitigating a dual influenza/COVID-19 epidemic,” Rebeccah L. Sokol, PhD, of Wayne State University, Detroit, and Anna H. Grummon, PhD, of Harvard School of Public Health, Boston, reported in Pediatrics.

Although the pandemic has increased acceptance of some healthy behaviors including handwashing and social distancing, the impact on influenza vaccination rates remains unknown, they said.

To assess parents’ current intentions for flu vaccination of young children this season, the researchers conducted an online survey of 2,164 parents or guardians of children aged between 6 months and 5 years in the United States. The 15-minute online survey was conducted in May 2020 and participants received gift cards. The primary outcome was the impact of the COVID-19 pandemic on parental intentions for having their child vaccinated against seasonal flu this year.

“We measured change categorically, with response options ranging from 1 (I became much less likely to get my child the flu shot next year) to 5 (I became much more likely to get my child the flu shot next year),” the researchers said.
 

Pandemic changes some parents’ plans

Overall, 60% of parents said that the ongoing pandemic had altered their flu vaccination intentions for their children. About 34% percent of parents whose children did not receive flu vaccine last year said they would not seek the vaccine this year because of the pandemic, compared with 25% of parents whose children received last year’s flu vaccine, a statistically significant difference (P < .001).

Approximately 21% of parents whose children received no flu vaccine last year said the pandemic made them more likely to seek vaccination for the 2020-2021 season, compared with 38% of parents whose children received last year’s flu vaccine.

“These results suggest that overall seasonal influenza vaccination rates may not increase simply because of an ongoing infectious disease pandemic. Instead, a significant predictor of future behavior remains past behavior,” Dr. Sokol and Dr. Grummon said.

The study findings were limited by several factors including the use of a convenience sample and the timing of the survey in May 2020, meaning that survey results might not be generalizable this fall as the pandemic persists, they noted. “Additionally, we assessed intentions to vaccinate; future research will clarify the COVID-19 pandemic’s influence on actual vaccination behaviors.”

The challenge of how to increase uptake of the influenza vaccine during the era of COVID-19 remains, and targeted efforts could include social norms messaging through social media, mass media, or health care providers to increase parents’ intentions to vaccinate, as well as vaccination reminders and presumptive announcements from health care providers that present vaccination as the default option, the researchers added.
 

Potential for ‘twindemic’ is real

The uptake of flu vaccination is especially important this year, Christopher J. Harrison, MD, director of the vaccine and treatment evaluation unit and professor of pediatrics at the University of Missouri–Kansas City, said in an interview.

“This year we are entering a flu season where the certainty of the timing as well as the potential severity of the season are not known. That said, social distancing and wearing masks – to the extent that enough people conform to COVID-19 precautions – could delay or even blunt the usual influenza season,” he noted.

Unfortunately, the Centers for Disease Control and Prevention and the Food and Drug Administration have had their credibility damaged by the challenges of creating a successful response on the fly to a uniquely multifaceted virus to which previous rules do not apply, Dr. Harrison said. In addition, public confidence was eroded when information about testing and reopening policies were released by non-CDC nonscientists and labeled “CDC recommended,” with no opportunity for the scientific community to correct inaccuracies.

“The current study reveals that public trust in influenza vaccine and indirectly in health authorities has been affected by the pandemic,” said Dr. Harrison. “Vaccine hesitancy has increased somewhat even among previous vaccine accepters. One wonders if promises of a quick COVID-19 vaccine increased mistrust of the FDA because of safety concerns, even among the most ardent provaccine population, and whether these concerns are bleeding over into influenza vaccine concerns.

“This only adds to the anxiety that families feel about visiting any medical facility for routine vaccines while the pandemic rages, and we now are in a fall SARS-CoV-2 resurgence,” he added.

Although the current study data are concerning, “there could still be a net gain of pediatric influenza vaccine uptake this season because the 34% less likely to immunize among previously nonimmunizing families would be counterbalanced by 21% of the same group being more likely to immunize their children [theoretical net loss of 13%],” Dr. Harrison explained. “But the pandemic seems to have motivated previously influenza-immunizing families, i.e. while 24% were less likely, 39% are more likely to immunize [theoretical net gain of 15%]. That said, we would still be way short of the number needed to get to herd immunity.”

Dr. Harrison said he found the findings somewhat surprising, but perhaps he should not have. “I had hoped for more acceptance rather than most people staying in their prior vaccine ‘opinion lanes,’ ending up with likely little overall net change in plans to immunize despite increased health awareness caused by a pandemic.”

However, “the U.S. population has been polarized on vaccines and particularly influenza vaccines for more than 50 years, so why would a pandemic make us less polarized, particularly when the pandemic itself has been a polarizing event?” he questioned.

The greatest barriers to flu vaccination for children this year include a lack of motivation among families to visit immunization sites, given the ongoing need for social distancing and masks, Dr. Harrison said.

“Another barrier is the waning public confidence in our medical/scientific national leaders and organizations,” he emphasized. “This makes it crucial that primary care providers step up and be extra strong vaccine advocates, despite the fact that pandemic economics and necessary safety processes have stressed providers and devastated practices. Indeed, in times of medical stress, no one gets more trust from families than their own personal provider.”

Ultimately, avenues for future research include asking diverse groups of families what they feel they need to hear to be more engaged in immunizing children against influenza. But for now, the current study findings identify that “the public is not uniformly responding to the pandemic’s influence on their likelihood of immunizing their children against influenza,” Dr. Harrison said.

“We now know the size of the problem and hopefully governments, public health organizations, pediatric advocates and clinical care givers can find ways to magnify the message that a pandemic year is not a year to avoid seasonal influenza vaccine unless one has a true contraindication,” Dr. Harrison said.

In addition, “one wonders if the poll were taken today – post the president’s COVID-19 illness – would the answers be different?” he noted.

Dr. Sokol’s work was supported in part by the Eunice Kennedy Shriver National Institute of Child Health and Human Development but otherwise had no financial conflicts to disclose. Dr. Harrison disclosed that his institution receives grant funding from Merck, Pfizer, and GlaxoSmithKline for pediatric noninfluenza vaccine studies on which he is a subinvestigator, and support from the CDC for pediatric respiratory and gastrointestinal virus surveillance studies on which he is an investigator.

The adjuvanted recombinant zoster vaccine Shingrix appears to be effective in older adults with autoimmune diseases who are not receiving treatment regimens that suppress the immune system, according to a post hoc analysis of patients in two clinical trials.

jarun011/thinkstock

A two-dose regimen of Shingrix was effective in 90.5% of a subset of patients in two phase 3 clinical trials of adults who were aged at least 50 years, according to Alemnew F. Dagnew, MD, of GlaxoSmithKline and colleagues. The lowest rates of effectiveness with Shingrix, for patients aged between 70-79 years, was 84.4%, the researchers reported in Rheumatology.

The CDC recommends adults aged at least 50 years receive two doses of Shingrix to help prevent reoccurrence of herpes zoster, or Zostavax (zoster vaccine live) if adults are allergic to components of the Shingrix vaccine or have tested negative for varicella zoster virus immunity.

Dr. Dagnew and colleagues evaluated Shingrix in 983 patients who received two doses of Shingrix and 960 patients who received placebo from the ZOE-50 and ZOE-70 trials, where each dose was administered at least 2 months apart. The mean age of patients in both groups was 68.8 years in the Shingrix group and 69.4 years in the placebo group, and more than half of patients in both Shingrix (59.9%) and placebo groups (60.8%) were women. About 7% of the patients in two clinical trial had a pIMD.

At enrollment, the most common preexisting immune-mediated disorders (pIMDs) were psoriasis (215 patients taking Shingrix vs. 239 patients on placebo), spondyloarthropathy (109 patients taking Shingrix vs. 89 patients on placebo), rheumatoid arthritis (96 patients taking Shingrix vs. 94 patients on placebo), and celiac disease (41 patients taking Shingrix vs. 34 patients on placebo). Dr. Dagnew and colleagues examined the subgroup of patients with pIMDs for safety and vaccine efficacy, which was defined as not developing herpes zoster before the second dose.

Overall, the efficacy of Shingrix was 90.5% across all age groups (95% confidence interval, 73.5%-97.5%), with the group aged between 70-79 years having the lowest rate of effectiveness (95% CI, 30.8%-98.3%). The rate of severe adverse events was 14.6% in the Shingrix group and 11.7% in the placebo group between the first Shingrix dose and for up to 1 year after the second dose. The most common adverse events were infections and infestations as well as cardiac disorders. “Our data show a balance between study groups in the frequency and nature of SAEs, confirming the favorable safety profile of [Shingrix] in populations with pIMDs,” Dr. Dagnew and colleagues wrote.

The researchers acknowledged that the ZOE-50/70 studies were underpowered to detect the efficacy and safety of Shingrix in individuals with pIMDs but said that the large number of participants in the studies let them estimate efficacy and adverse events for this subgroup. They also noted there was no randomization of pIMDs at enrollment, even though pIMDs occurred at similar rates between Shingrix and placebo groups.

This study was funded by GlaxoSmithKline; the company helped with conducting and analyzing the study and also provided the costs associated with publishing it. Five authors reported being an employee of GlaxoSmithKline during the time the work was conducted, and four of the five own stock in the company. One author is now an employee of UCB. One author reported having served on the advisory boards for Merck Sharp & Dohme, GlaxoSmithKline, and Curevo.

A two-dose regimen of Shingrix was effective in 90.5% of a subset of patients in two phase 3 clinical trials of adults who were aged at least 50 years, according to Alemnew F. Dagnew, MD, of GlaxoSmithKline and colleagues. The lowest rates of effectiveness with Shingrix, for patients aged between 70-79 years, was 84.4%, the researchers reported in Rheumatology.

The CDC recommends adults aged at least 50 years receive two doses of Shingrix to help prevent reoccurrence of herpes zoster, or Zostavax (zoster vaccine live) if adults are allergic to components of the Shingrix vaccine or have tested negative for varicella zoster virus immunity.

Dr. Dagnew and colleagues evaluated Shingrix in 983 patients who received two doses of Shingrix and 960 patients who received placebo from the ZOE-50 and ZOE-70 trials, where each dose was administered at least 2 months apart. The mean age of patients in both groups was 68.8 years in the Shingrix group and 69.4 years in the placebo group, and more than half of patients in both Shingrix (59.9%) and placebo groups (60.8%) were women. About 7% of the patients in two clinical trial had a pIMD.

At enrollment, the most common preexisting immune-mediated disorders (pIMDs) were psoriasis (215 patients taking Shingrix vs. 239 patients on placebo), spondyloarthropathy (109 patients taking Shingrix vs. 89 patients on placebo), rheumatoid arthritis (96 patients taking Shingrix vs. 94 patients on placebo), and celiac disease (41 patients taking Shingrix vs. 34 patients on placebo). Dr. Dagnew and colleagues examined the subgroup of patients with pIMDs for safety and vaccine efficacy, which was defined as not developing herpes zoster before the second dose.

Quadrivalent human papillomavirus (HPV) vaccination was associated with a substantial reduction in the incidence of cervical cancer in a Swedish review of more than 1 million girls and women vaccinated from 2006 to 2017.

It’s been shown that the vaccine (Gardasil) helps prevent genital warts and high-grade cervical lesions, but until now, data on the ability of the vaccine to prevent cervical cancer, although widely assumed, had been lacking.

“Our results extend [the] knowledge base by showing that quadrivalent HPV vaccination is also associated with a substantially reduced risk of invasive cervical cancer, which is the ultimate intent of HPV vaccination programs,” said investigators led by Jiayao Lei, PhD, a researcher in the department of medical epidemiology and biostatistics at the Karolinska Institute, Stockholm.

The study was published online Oct. 1 in the New England Journal of Medicine.

“This work provides evidence of actual cancer prevention,” commented Diane Harper, MD, an HPV expert and professor in the departments of family medicine and obstetrics & gynecology at the University of Michigan, Ann Arbor. She was the principal investigator on the original Gardasil trial.

This study “shows that the quadrivalent HPV vaccine provides prevention from the sexually transmitted HPV infection that actually reduces the incidence of cervical cancer in young women up to 30 years of age,” she said when approached for comment.

However, she also added a note of caution. These new results show “that vaccinated women still develop cervical cancer, but at a slower rate. This makes the connection between early-age vaccination and continued adult life screening incredibly important,” Dr. Harper said in an interview

Cervical cancer was diagnosed in 19 of the 527,871 women (0.004%) who had received at least one dose of the vaccine versus 538 among the 1,145,112 women (0.05%) who had not.

The cumulative incidence was 47 cases per 100,000 vaccinated women and 94 cases per 100,000 unvaccinated women. The cervical cancer incidence rate ratio for the comparison of vaccinated versus unvaccinated women was 0.37 (95% confidence interval, 0.21-0.57).

The risk reduction was even greater among women who had been vaccinated before the age of 17, with a cumulative incidence of 4 versus 54 cases per 100,000 for women vaccinated after age 17. The incidence rate ratio was 0.12 (95% CI, 0.00-0.34) for women who had been vaccinated before age 17 versus 0.47 (95% CI, 0.27-0.75) among those vaccinated from age 17 to 30 years.

Overall, “the risk of cervical cancer among participants who had initiated vaccination before the age of 17 years was 88% lower than among those who had never been vaccinated,” the investigators noted.

These results “support the recommendation to administer quadrivalent HPV vaccine before exposure to HPV infection to achieve the most substantial benefit,” the investigators wrote.
 

Details of the Swedish review

For their review, Dr. Lei and colleagues used several Swedish demographic and health registries to connect vaccination status to incident cervical cancers, using the personal identification numbers Sweden issues to residents.

Participants were followed starting either on their 10th birthday or on Jan. 1, 2006, whichever came later. They were followed until, among other things, diagnosis of invasive cervical cancer; their 31st birthday; or until Dec. 31, 2017, whichever came first.

The quadrivalent HPV vaccine, approved in Sweden in 2006, was used almost exclusively during the study period. Participants were considered vaccinated if they had received only one shot, but the investigators set out to analyze a relationship between the incidence of invasive cervical cancer and the number of shots given.

Among other things, the team controlled for age at follow-up, calendar year, county of residence, maternal disease history, and parental characteristics, including education and household income.

The investigators commented that it’s possible that HPV-vaccinated women could have been generally healthier than unvaccinated women and so would have been at lower risk for cervical cancer.

“Confounding by lifestyle and health factors in the women (such as smoking status, sexual activity, oral contraceptive use, and obesity) cannot be excluded; these factors are known to be associated with a risk of cervical cancer,” the investigators wrote.

HPV is also associated with other types of cancer, including anal and oropharyngeal cancers. But these cancers develop over a longer period than cervical cancer.

Dr. Harper noted that the “probability of HPV 16 cancer by time since infection peaks at 40 years after infection for anal cancers and nearly 50 years after infection for oropharyngeal cancers. This means that registries, such as in Sweden, for the next 40 years will record the evidence to say whether HPV vaccination lasts long enough to prevent [these] other HPV 16–associated cancers occurring at a much later time in life.”

The work was funded by the Swedish Foundation for Strategic Research, the Swedish Cancer Society, and the Swedish Research Council and by the China Scholarship Council. Dr. Lei and two other investigators reported HPV vaccine research funding from Merck, the maker of Gardasil. Harper disclosed no relevant financial relationships.

Johnson & Johnson (J&J) on Wednesday said it advanced into phase 3 testing of its COVID-19 vaccine candidate, which uses the same technology as an Ebola vaccine already approved by European regulators.

The National Institute of Allergy and Infectious Diseases, which is aiding Johnson & Johnson with development, described this in a news release as the fourth phase 3 clinical trial of evaluating an investigational vaccine for coronavirus disease.

This NIAID tally tracks products likely to be presented soon for Food and Drug Administration approval. (The World Health Organization’s COVID vaccine tracker lists nine candidates as having reached this stage, including products developed in Russia and China.)

As many as 60,000 volunteers will be enrolled in the trial, with about 215 clinical research sites expected to participate, NIAID said. The vaccine will be tested in the United States and abroad.

The start of this test, known as the ENSEMBLE trial, follows positive results from a Phase 1/2a clinical study, which involved a single vaccination. The results of this study have been submitted to medRxiv and are set to be published online imminently.

New Brunswick, N.J–based J&J said it intends to offer the vaccine on “a not-for-profit basis for emergency pandemic use.” If testing proceeds well, J&J might seek an emergency use clearance for the vaccine, which could possibly allow the first batches to be made available in early 2021.

J&J’s vaccine is unusual in that it will be tested based on a single dose, while other advanced candidates have been tested in two-dose regimens.

J&J on Wednesday also released the study protocol for its phase 3 test. The developers of the other late-stage COVID vaccine candidates also have done this, as reported by Medscape Medical News. Because of the great interest in the COVID vaccine, the American Medical Association had last month asked the FDA to keep physicians informed of their COVID-19 vaccine review process.
 

Trials and tribulations

One of these experimental COVID vaccines already has had a setback in phase 3 testing, which is a fairly routine occurrence in drug development. But with a pandemic still causing deaths and disrupting lives around the world, there has been intense interest in each step of the effort to develop a COVID vaccine.

AstraZeneca PLC earlier this month announced a temporary cessation of all their coronavirus vaccine trials to investigate an “unexplained illness” that arose in a participant, as reported by Medscape Medical News.

On September 12, AstraZeneca announced that clinical trials for the AZD1222, which it developed with Oxford University, had resumed in the United Kingdom. On Wednesday, CNBC said Health and Human Services Secretary Alex Azar told the news station that AstraZeneca’s late-stage coronavirus vaccine trial in the United States remains on hold until safety concerns are resolved, a critical issue with all the fast-track COVID vaccines now being tested.

“Look at the AstraZeneca program, phase 3 clinical trial, a lot of hope. [A] single serious adverse event report in the United Kingdom, global shutdown, and [a] hold of the clinical trials,” Mr. Azar told CNBC.

The New York Times has reported on concerns stemming from serious neurologic illnesses in two participants, both women, who received AstraZeneca’s experimental vaccine in Britain.

The Senate Health, Education, Labor and Pensions Committee on Wednesday separately held a hearing with the leaders of the FDA and the Centers of Disease Control and Prevention, allowing an airing of lawmakers’ concerns about a potential rush to approve a COVID vaccine.
 

Details of J&J trial

The J&J trial is designed primarily to determine if the investigational vaccine can prevent moderate to severe COVID-19 after a single dose. It also is designed to examine whether the vaccine can prevent COVID-19 requiring medical intervention and if the vaccine can prevent milder cases of COVID-19 and asymptomatic SARS-CoV-2 infection, NIAID said.

Principal investigators for the phase 3 trial of the J & J vaccine are Paul A. Goepfert, MD, director of the Alabama Vaccine Research Clinic at the University of Alabama in Birmingham; Beatriz Grinsztejn, MD, PhD, director of the Laboratory of Clinical Research on HIV/AIDS at the Evandro Chagas National Institute of Infectious Diseases-Oswaldo Cruz Foundation in Rio de Janeiro, Brazil; and Glenda E. Gray, MBBCh, president and chief executive officer of the South African Medical Research Council and coprincipal investigator of the HIV Vaccine Trials Network.

The start of this test, known as the ENSEMBLE trial, follows positive results from a Phase 1/2a clinical study, which involved a single vaccination. The results of this study have been submitted to medRxiv and are set to be published online imminently.

New Brunswick, N.J–based J&J said it intends to offer the vaccine on “a not-for-profit basis for emergency pandemic use.” If testing proceeds well, J&J might seek an emergency use clearance for the vaccine, which could possibly allow the first batches to be made available in early 2021.

J&J’s vaccine is unusual in that it will be tested based on a single dose, while other advanced candidates have been tested in two-dose regimens.

J&J on Wednesday also released the study protocol for its phase 3 test. The developers of the other late-stage COVID vaccine candidates also have done this, as reported by Medscape Medical News. Because of the great interest in the COVID vaccine, the American Medical Association had last month asked the FDA to keep physicians informed of their COVID-19 vaccine review process.
 

Trials and tribulations

One of these experimental COVID vaccines already has had a setback in phase 3 testing, which is a fairly routine occurrence in drug development. But with a pandemic still causing deaths and disrupting lives around the world, there has been intense interest in each step of the effort to develop a COVID vaccine.

AstraZeneca PLC earlier this month announced a temporary cessation of all their coronavirus vaccine trials to investigate an “unexplained illness” that arose in a participant, as reported by Medscape Medical News.

On September 12, AstraZeneca announced that clinical trials for the AZD1222, which it developed with Oxford University, had resumed in the United Kingdom. On Wednesday, CNBC said Health and Human Services Secretary Alex Azar told the news station that AstraZeneca’s late-stage coronavirus vaccine trial in the United States remains on hold until safety concerns are resolved, a critical issue with all the fast-track COVID vaccines now being tested.

“Look at the AstraZeneca program, phase 3 clinical trial, a lot of hope. [A] single serious adverse event report in the United Kingdom, global shutdown, and [a] hold of the clinical trials,” Mr. Azar told CNBC.

The New York Times has reported on concerns stemming from serious neurologic illnesses in two participants, both women, who received AstraZeneca’s experimental vaccine in Britain.

The Senate Health, Education, Labor and Pensions Committee on Wednesday separately held a hearing with the leaders of the FDA and the Centers of Disease Control and Prevention, allowing an airing of lawmakers’ concerns about a potential rush to approve a COVID vaccine.
 

Details of J&J trial

The J&J trial is designed primarily to determine if the investigational vaccine can prevent moderate to severe COVID-19 after a single dose. It also is designed to examine whether the vaccine can prevent COVID-19 requiring medical intervention and if the vaccine can prevent milder cases of COVID-19 and asymptomatic SARS-CoV-2 infection, NIAID said.

Principal investigators for the phase 3 trial of the J & J vaccine are Paul A. Goepfert, MD, director of the Alabama Vaccine Research Clinic at the University of Alabama in Birmingham; Beatriz Grinsztejn, MD, PhD, director of the Laboratory of Clinical Research on HIV/AIDS at the Evandro Chagas National Institute of Infectious Diseases-Oswaldo Cruz Foundation in Rio de Janeiro, Brazil; and Glenda E. Gray, MBBCh, president and chief executive officer of the South African Medical Research Council and coprincipal investigator of the HIV Vaccine Trials Network.

The companies behind three major COVID-19 vaccines in development released the protocols of their trials, outlining their expectations for participant enrollment, benchmarks for vaccine efficacy, and more details about the makeup of each product.

Typically, manufacturers guard the specifics of preclinical vaccine trials. This rare move follows calls for greater transparency. For example, the American Medical Association wrote a letter in late August asking the Food and Drug Administration to keep physicians informed of their COVID-19 vaccine review process.

On September 17, ModernaTx released the phase 3 trial protocol for its mRNA-1273 SARS-CoV-2 vaccine. In short order, on September 19, Pfizer/BioNTech shared their phase 1/2/3 trial vaccine protocol. AstraZeneca, which is developing a vaccine along with Oxford University, also released its protocol.

The AstraZeneca vaccine trial made headlines recently for having to be temporarily halted because of unexpected illnesses that arose in two participants, according to the New York Times and other sources.

“I applaud the release of the clinical trial protocols by the companies. The public trust in any COVID-19 vaccine is paramount, especially given the fast timeline and perceived political pressures of these candidates,” Robert Kruse, MD, PhD, told Medscape Medical News when asked to comment.
 

AstraZeneca takes a shot at transparency

The three primary objectives of the AstraZeneca AZD1222 trial outlined in the 110-page protocol include estimating the efficacy, safety, tolerability, and reactogenicity associated with two intramuscular doses of the vaccine in comparison with placebo in adults.

The projected enrollment is 30,000 participants, and the estimated primary completion date is Dec. 2, 2020, according to information on clinicaltrials.gov.

“Given the unprecedented global impact of the coronavirus pandemic and the need for public information, AstraZeneca has published the detailed protocol and design of our AZD1222 clinical trial,” the company said in a statement. “As with most clinical development, protocols are not typically shared publicly due to the importance of maintaining confidentiality and integrity of trials.

“AstraZeneca continues to work with industry peers to ensure a consistent approach to sharing timely clinical trial information,” the company added.
 

Moderna methodology

The ModernaTX 135-page protocol outlines the primary trial objectives of evaluating efficacy, safety, and reactogenicity of two injections of the vaccine administered 28 days apart. Researchers also plan to randomly assign 30,000 adults to receive either vaccine or placebo. The estimated primary completion date is Oct. 27, 2022.

A statement that was requested from ModernaTX was not received by press time.
 

Pfizer protocol

In the Pfizer/BioNTech vaccine trial, researchers plan to evaluate different doses in different age groups in a multistep protocol. The trial features 20 primary safety objectives, which include reporting adverse events and serious adverse events, including any local or systemic events.

Efficacy endpoints are secondary objectives. The estimated enrollment is 29,481 adults; the estimated primary completion date is April 19, 2021.

“Pfizer and BioNTech recognize that the COVID-19 pandemic is a unique circumstance, and the need for transparency is clear,” Pfizer spokesperson Sharon Castillo told Medscape Medical News. By making the full protocol available, “we believe this will reinforce our long-standing commitment to scientific and regulatory rigor that benefits patients,” she said.

“Based on current infection rates, Pfizer and BioNTech continue to expect that a conclusive read-out on efficacy is likely by the end of October. Neither Pfizer nor the FDA can move faster than the data we are generating through our clinical trial,” Castillo said.

If clinical work and regulatory approval or authorization proceed as planned, Pfizer and BioNTech expect to supply up to 100 million doses worldwide by the end of 2020 and approximately 1.3 billion doses worldwide by the end of 2021.

Pfizer is not willing to sacrifice safety and efficacy in the name of expediency, Castillo said. “We will not cut corners in this pursuit. Patient safety is our highest priority, and Pfizer will not bring a vaccine to market without adequate evidence of safety and efficacy.”
 

A positive move

“COVID-19 vaccines will only be useful if many people are willing to receive them,” said Kruse, a postgraduate year 3 resident in the Department of Pathology at Johns Hopkins Medicine in Baltimore, Maryland.

“By giving the general public along with other scientists and physicians the opportunity to critique the protocols, everyone can understand what the metrics would be for an early look at efficacy,” Kruse said. He noted that information could help inform a potential FDA emergency use authorization.

Kruse has disclosed no relevant financial relationships.

When it comes to preventing infection in rheumatology patients, “vaccination is the best mode of infection protection” and works synergistically with masks and hand washing, according to Leonard H. Calabrese, DO.

“Patients with rheumatic diseases have increased morbidity and mortality [from infection] and a lot of risk factors, including age, comorbidities, cytopenias, and extra-articular disease immunosuppression,” he said in a virtual presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.

Unfortunately, vaccination uptake remains “much lower than we would like in this country,” he said. Notably, influenza vaccination remains well below the World Health Organization target of 75%, he said.
 

Influenza vaccination

Flu vaccination will be even more important this year in the context of the COVID-19 pandemic, said Dr. Calabrese, professor of medicine and the RJ Fasenmyer Chair of Clinical Immunology at the Cleveland Clinic in Ohio. “For everyone who comes in with a respiratory illness, we will have to figure out whether it is flu or COVID,” he emphasized.

The Centers for Disease Control and Prevention recommendations include a detailed special considerations section for patients with immunocompromising conditions; “the notes have everything you need to know” about advising rheumatology patients, most of whom can safely receive a flu vaccine, he said.

One concern that always comes up is whether an antibody response will be suppressed based on therapy, Dr. Calabrese noted. Two major drugs with the greatest ability to reduce response are methotrexate and rituximab, he said. His tip: “Withhold methotrexate for two doses following seasonal flu vaccination.” This advice stems from a series of “practice-changing” studies by Park et al. published in 2017, 2018, and 2019 that showed benefit in withholding methotrexate for two doses following vaccination.

In the past, high-dose trivalent flu vaccines have been more expensive, and not necessarily practice changing, with studies showing varying clinical effectiveness and cost-effectiveness, Dr. Calabrese said. This year, a high-dose quadrivalent vaccine should be available that showed a 24% improvement in protection from all strains of influenza, compared with the standard vaccine in a head-to-head, randomized, controlled trial, he noted.

“All patients in rheumatology practices should get a flu vaccine,” with a 2-week hold on methotrexate following vaccination, he advised, and those aged 65 years and older should receive the high-dose quadrivalent. Younger patients on immunosuppressive therapy also might be considered for the high-dose vaccine, he said.

Pneumococcal vaccination

Dr. Calabrese also emphasized the value of pneumococcal vaccines for rheumatology patients. “The mortality for invasive disease ranges from 5% to 32%, but patients with immunocompromising conditions are at increased risk.”

Dr. Calabrese added a note on safety: Patients with cryopyrin-associated periodic syndrome (CAPS), a rare hereditary inflammatory disorder with cutaneous, neurologic, ophthalmologic, and rheumatologic manifestations, may have severe local and systemic reactions to the 23-valent polysaccharide vaccine (PPSV23), he said.

However, immunization against pneumococcal disease is safe and effective for most patients with autoimmune and inflammatory disorders regardless of their current therapy, he said. As with influenza, the CDC’s vaccination recommendations provide details for special situations, including immunocompromised individuals, he noted.

Dr. Calabrese recommended the 13-valent pneumococcal conjugate vaccine (PCV13) as soon as possible for rheumatology patients who have never been vaccinated, with follow-up doses of the 23-valent polysaccharide vaccine (PPSV23) at least 8 weeks later, and a PPSV23 booster 5 years after the first PPSV23 dose.
 

Protecting against shingles

When it comes to managing the varicella zoster virus (VZV) in immunocompromised patients, “prevention is preferable to treatment, as our patients are particularly vulnerable because of age and declining immunity,” Dr. Calabrese said.

Prevention is important because “once herpes zoster develops, the available treatments, including antiviral therapy, do not prevent postherpetic neuralgia in all patients,” he emphasized. “The treatments are complicated and not always effective,” he added.

The complications of zoster are well known, but recent data show an increased risk of cardiovascular disease as well, Dr. Calabrese said. “All the more reason to protect rheumatology patients from incident zoster,” he said.

Currently, the nonlive recombinant subunit zoster vaccine (Shingrix) is the preferred option for VZV vaccination according to the CDC’s Advisory Committee on Immunization Practices, Dr. Calabrese said. The CDC initially recommended its use to prevent herpes zoster and related complications in all immunocompetent adults aged 50 years and older; in an update, a C-level recommendation extends to “all patients aged 50 with or without immunosuppressive illnesses regardless of previous Zostavax exposure,” Dr. Calabrese said. “All patients on or starting [Janus] kinase inhibitors, regardless of age, should be considered” to receive the herpes zoster vaccine, he noted.

In general, promoting vaccination for rheumatology patients and for all patients is a multipronged effort that might include reminders, rewards, education, and standing orders, Dr. Calabrese said. Clinicians must continue to educate patients not only by strongly recommending the appropriate vaccines, but dispelling myths about vaccination, addressing fears, and providing current and accurate information, he said.

Dr. Calabrese disclosed relationships with AbbVie, Bristol-Myers Squibb, Crescendo, Genentech, Gilead, GlaxoSmithKline, Janssen, Novartis, Pfizer, Sanofi-Regeneron, and UCB.
