Vaccines

I received a call late one night from a colleague in the emergency department of the children’s hospital. “This 2-year-old has a fever, cough, red eyes, and an impressive rash. I’ve personally never seen a case of measles, but I’m worried given that this child has never received the MMR vaccine.”

By the end of the call, I was worried too. Measles is a febrile respiratory illness classically accompanied by cough, coryza, conjunctivitis, and a characteristic maculopapular rash that begins on the face and spreads to the trunk and limbs. It is also highly contagious: 90% percent of susceptible, exposed individuals become infected.

Admittedly, measles is rare. Just 118 cases were reported in the United States in 2022, but 83 of those were in Columbus just 3 hours from where my colleague and I live and work. According to City of Columbus officials, the outbreak occurred almost exclusively in unimmunized children, the majority of whom were 5 years and younger. An unexpectedly high number of children were hospitalized. Typically, one in five people with measles will require hospitalization. In this outbreak, 33 children have been hospitalized as of Jan. 10.

Public health experts warn that 2023 could be much worse unless we increase measles immunization rates in the United States and globally. Immunization of around 95% of eligible people with two doses of measles-containing vaccine is associated with herd immunity. Globally, we’re falling short. Only 81% of the world’s children have received their first measle vaccine dose and only 71% have received the second dose. These are the lowest coverage rates for measles vaccine since 2008.

A 2022 joint press release from the Centers for Disease Control and Prevention and the World Health Organization noted that “measles anywhere is a threat everywhere, as the virus can quickly spread to multiple communities and across international borders.” Some prior measles outbreaks in the United States have started with a case in an international traveler or a U.S. resident who contracted measles during travel abroad.

In the United States, the number of children immunized with multiple routine vaccines has fallen in the last couple of years, in part because of pandemic-related disruptions in health care delivery. Increasing vaccine hesitancy, fueled by debates over the COVID-19 vaccine, may be slowing catch-up immunization in kids who fell behind.

Investigators from Emory University, Atlanta, and Marshfield Clinic Research Institute recently estimated that 9,145,026 U.S. children are susceptible to measles. If pandemic-level immunization rates continue without effective catch-up immunization, that number could rise to more than 15 million.

School vaccination requirements support efforts to ensure that kids are protected against vaccine-preventable diseases, but some data suggest that opposition to requiring MMR vaccine to attend public school is growing. According to a 2022 Kaiser Family Foundation Vaccine Monitor survey, 28% of U.S. adults – and 35% of parents of children under 18 – now say that parents should be able to decide to not vaccinate their children for measles, mumps, and rubella. That’s up from 16% of adults and 23% of parents in a 2019 Pew Research Center poll.

Public confidence in the benefits of MMR has also dropped modestly. About 85% of adults surveyed said that the benefits of MMR vaccine outweigh the risk, down from 88% in 2019. Among adults not vaccinated against COVID-19, only 70% said that benefits of these vaccines outweigh the risks.

While the WHO ramps up efforts to improve measles vaccination globally, pediatric clinicians can take steps now to mitigate the risk of measles outbreaks in their own communities. Query health records to understand how many eligible children in your practice have not yet received MMR vaccine. Notify families that vaccination is strongly recommended and make scheduling an appointment to receive vaccine easy. Some practices may have the bandwidth to offer evening and weekend hours for vaccine catch-up visits.

Curious about immunization rates in your state? The American Academy of Pediatrics has an interactive map that reports immunization coverage levels by state and provides comparisons to national rates and goals.

Prompt recognition and isolation of individuals with measles, along with prophylaxis of susceptible contacts, can limit community transmission. Measles can resemble other illnesses associated with fever and rash. Washington state has developed a screening tool to assist with recognition of measles. The CDC also has a measles outbreak toolkit that includes resources that outline clinical features and diagnoses, as well as strategies for talking to parents about vaccines.

The newest subvariant of Omicron, XBB.1.5, is so transmissible that everybody is at risk of catching it, even if they’ve already been infected and are fully vaccinated, a health expert told USA Today.

“It’s crazy infectious,” said Paula Cannon, PhD, a virologist at the University of Southern California, Los Angeles. “All the things that have protected you for the past couple of years, I don’t think are going to protect you against this new crop of variants.” 

XBB.1.5 is spreading quickly in the United States. It accounted for 27.6% of cases in the country in the week ending on Jan. 7, up from about 1% of cases at one point in December, according to the Centers for Disease Control and Prevention. It’s especially prevalent in the Northeast, now accounting for more than 70% of the cases in that region.

It’s spreading across the globe, too. Maria Van Kerkhove, PhD, technical lead of the World Health Organization, has called XBB.1.5 is “the most transmissible subvariant that has been detected yet.” 

Ashish Jha, MD, the White House COVID-19 response coordinator, tweeted a few days ago that the spread of XBB.1.5 is “stunning” but cautioned that it’s unclear if the symptoms of infection will be more severe than for previous variants.

“Whether we’ll have an XBB.1.5 wave (and if yes, how big) will depend on many factors including immunity of the population, people’s actions, etc.,” he tweeted. 

He urged people to get up to date on their boosters, wear a snug-fitting mask, and avoid crowded indoor spaces. He noted that people who haven’t been infected recently or haven’t gotten the bivalent booster likely have little protection against infection.

The symptoms for XBB.1.5 appear to be the same as for other versions of COVID-19. However, it’s less common for people infected with XBB.1.5 to report losing their sense of taste and smell, USA Today reported.

The SARS-CoV-2 virus can be found throughout the entire body and remain present for more than 7 months, researchers discovered.

A study on the subject was published in the journal Nature. The researchers completed autopsies from April 2020 to March 2021 of 44 unvaccinated people who had severe COVID-19. The median age was 62.5 years old, and 30% were female. Extensive brain sampling was done for 11 cases.

Because of its nature as a respiratory illness, SARS-CoV-2 was most widespread in the respiratory system such as in the lungs. But it was also found in 79 other body locations, including the heart, kidneys, liver, muscles, nerves, reproductive tract, and eyes. 

The researchers said their work shows the SARS-CoV-2 “is capable of infecting and replicating within the human brain.” They also said their results indicate the virus spreads via the blood early during infection, which “seeds the virus throughout the body following infection of the respiratory tract.”

The authors noted that, while the virus was found outside the respiratory tract, they did not find signs of inflammation beyond the respiratory system.

The results will help narrow down treatments for long COVID, and particularly support the idea of using the antiviral drug Paxlovid to treat long COVID, according to a blog post from the National Institute of Allergy and Infectious Diseases. A clinical trial is already underway examining the treatment, and results are expected in January 2024.

Participation in the first 2 years of Maryland’s Advanced Primary Care Program (MDPCP) was associated with better COVID-19 outcomes compared with a matched group not involved with the program, new data indicate.

The better outcomes were seen in higher vaccination rates and fewer infections, hospitalizations, and deaths from the disease, according to study authors, led by Emily Gruber, MBA, MPH, with the Maryland Primary Care Program, Maryland Department of Health in Baltimore.

The results were published online in JAMA Network Open.

The study population was divided into MDPCP participants (n = 208,146) and a matched cohort (n = 37,203) of beneficiaries not attributed to MDPCP practices but who met eligibility criteria for study participation from Jan. 1, 2020, through Dec. 31, 2021.
 

More vaccinations, more antibody treatments

Researchers broke down the comparisons of better outcomes: 84.47% of MDPCP beneficiaries were fully vaccinated vs. 77.93% of nonparticipating beneficiaries (P less than .001). COVID-19–positive program beneficiaries also received monoclonal antibody treatment more often (8.45% vs. 6.11%; P less than .001).

Plus, program participants received more care via telehealth (62.95% vs. 54.53%; P less than .001) compared with those not participating.

Regarding secondary outcomes, MDPCP beneficiaries had lower rates of COVID cases (6.55% vs. 7.09%; P less than .001), lower rates of COVID-19 hospitalizations (1.81% vs. 2.06%; P = .001), and lower rates of death due to COVID-19 (0.56% vs. 0.77%; P less than .001).
 

Program components

Enrollment in the MDPCP is voluntary, and primary care practices can apply each year to be part of the program.

The model integrates primary care and public health in the pandemic response. It was created by the Maryland Department of Health (MDH) and the Centers for Medicare & Medicaid Services (CMS).

It expands the role of primary care to include services such as expanded care management, integrated behavioral health, data-driven care, and screenings and referrals to address social needs.

Coauthor Howard Haft, MD, MMM, with the Maryland Department of Public Health, said in an interview that among the most important factors in the program’s success were giving providers vaccines to distribute and then giving providers data on how many patients are vaccinated, and who’s not vaccinated but at high risk, and how those rates compare to other practices.

As to whether this could be a widespread model, Dr. Haft said, “It’s highly replicable.”

“Every state in the nation overall has all of these resources. It’s a matter of having the operational and political will to put those resources together. Almost every state has the technological ability to use their health information exchange to help tie pieces together.”
 

Vaccines and testing made available to providers

Making ample vaccines and testing available to providers in their offices helped patients get those services in a place they trust, Dr. Haft said.

The model also included a payment system for providers that included a significant amount of non–visit-based payments when many locations were closed in the height of the pandemic.

“That helped financially,” as did providing free telehealth platforms to practices with training on how to use them, Dr. Haft said.
 

‘Innovative and important’

Renu Tipirneni, MD, an assistant professor of internal medicine at the University of Michigan and at the Institute for Healthcare Policy and Innovation in Ann Arbor, said Maryland is out front putting into practice what practices nationwide aspire to do – coordinating physical and mental health and social needs and integrating primary and public health. Dr. Tipirneni, who was not involved with the study, said she was impressed the researchers were able to show statistically significant improvement with COVID-19 outcomes in the first 2 years.

“In terms of health outcomes, we often have to wait longer to see good outcomes,” she said. “It’s a really innovative and important model.”

She said states can learn from each other and this model is an example.

Integrating primary care and public health and addressing social needs may be the biggest challenges for states, she said, as those realms typically have been siloed.

“But they may be the key components to achieving these outcomes,” she said.
 

Take-home message

The most important benefit of the program is that data suggest it saves lives, according to Dr. Haft. While the actual difference between COVID deaths in the program and nonprogram groups was small, multiplying that savings across the nation shows substantial potential benefit, he explained.

“At a time when we were losing lives at an unconscionable rate, we were able to make a difference in saving lives,” Dr. Haft said.

Authors report no relevant financial disclosures.

The study received financial support from the Maryland Department of Health.

Dr. Tiperneni is helping evaluate Michigan’s Medicaid contract.

Participation in the first 2 years of Maryland’s Advanced Primary Care Program (MDPCP) was associated with better COVID-19 outcomes compared with a matched group not involved with the program, new data indicate.

The better outcomes were seen in higher vaccination rates and fewer infections, hospitalizations, and deaths from the disease, according to study authors, led by Emily Gruber, MBA, MPH, with the Maryland Primary Care Program, Maryland Department of Health in Baltimore.

The results were published online in JAMA Network Open.

The study population was divided into MDPCP participants (n = 208,146) and a matched cohort (n = 37,203) of beneficiaries not attributed to MDPCP practices but who met eligibility criteria for study participation from Jan. 1, 2020, through Dec. 31, 2021.
 

More vaccinations, more antibody treatments

Researchers broke down the comparisons of better outcomes: 84.47% of MDPCP beneficiaries were fully vaccinated vs. 77.93% of nonparticipating beneficiaries (P less than .001). COVID-19–positive program beneficiaries also received monoclonal antibody treatment more often (8.45% vs. 6.11%; P less than .001).

Plus, program participants received more care via telehealth (62.95% vs. 54.53%; P less than .001) compared with those not participating.

Regarding secondary outcomes, MDPCP beneficiaries had lower rates of COVID cases (6.55% vs. 7.09%; P less than .001), lower rates of COVID-19 hospitalizations (1.81% vs. 2.06%; P = .001), and lower rates of death due to COVID-19 (0.56% vs. 0.77%; P less than .001).
 

Program components

Enrollment in the MDPCP is voluntary, and primary care practices can apply each year to be part of the program.

The model integrates primary care and public health in the pandemic response. It was created by the Maryland Department of Health (MDH) and the Centers for Medicare & Medicaid Services (CMS).

It expands the role of primary care to include services such as expanded care management, integrated behavioral health, data-driven care, and screenings and referrals to address social needs.

Coauthor Howard Haft, MD, MMM, with the Maryland Department of Public Health, said in an interview that among the most important factors in the program’s success were giving providers vaccines to distribute and then giving providers data on how many patients are vaccinated, and who’s not vaccinated but at high risk, and how those rates compare to other practices.

As to whether this could be a widespread model, Dr. Haft said, “It’s highly replicable.”

“Every state in the nation overall has all of these resources. It’s a matter of having the operational and political will to put those resources together. Almost every state has the technological ability to use their health information exchange to help tie pieces together.”
 

Vaccines and testing made available to providers

Making ample vaccines and testing available to providers in their offices helped patients get those services in a place they trust, Dr. Haft said.

The model also included a payment system for providers that included a significant amount of non–visit-based payments when many locations were closed in the height of the pandemic.

“That helped financially,” as did providing free telehealth platforms to practices with training on how to use them, Dr. Haft said.
 

‘Innovative and important’

Renu Tipirneni, MD, an assistant professor of internal medicine at the University of Michigan and at the Institute for Healthcare Policy and Innovation in Ann Arbor, said Maryland is out front putting into practice what practices nationwide aspire to do – coordinating physical and mental health and social needs and integrating primary and public health. Dr. Tipirneni, who was not involved with the study, said she was impressed the researchers were able to show statistically significant improvement with COVID-19 outcomes in the first 2 years.

“In terms of health outcomes, we often have to wait longer to see good outcomes,” she said. “It’s a really innovative and important model.”

She said states can learn from each other and this model is an example.

Integrating primary care and public health and addressing social needs may be the biggest challenges for states, she said, as those realms typically have been siloed.

“But they may be the key components to achieving these outcomes,” she said.
 

Take-home message

The most important benefit of the program is that data suggest it saves lives, according to Dr. Haft. While the actual difference between COVID deaths in the program and nonprogram groups was small, multiplying that savings across the nation shows substantial potential benefit, he explained.

I guess we shouldn’t be surprised that vaccination rates in this country fell during the frenzy created by the COVID pandemic. We had a lot on our plates. Schools closed and many of us retreated into what seemed to be the safety of our homes. Parents were reluctant to take their children anywhere, let alone a pediatrician’s office. State health agencies wisely focused on collecting case figures and then shepherding the efforts to immunize against SARS-CoV-2 once vaccines were available. Tracking and promoting the existing children’s vaccinations fell off the priority list, even in places with exemplary vaccination rates.

Whether or not the pandemic is over continues to be a topic for debate, but there is clearly a general shift toward a new normalcy. However, vaccination rates of our children have not rebounded to prepandemic levels. In fact, in some areas they are continuing to fall.

In a recent guest essay in the New York Times, Ezekiel J. Emmanuel, MD, PhD, a physician and professor of medical ethics and health policy at the University of Pennsylvania, and Matthew Guido, his research assistant, explore the reasons for this lack of a significant rebound. The authors cite recent outbreaks of measles in Ohio and polio in New York City as examples of the peril we are facing if we fail to reverse the trend. In some areas measles vaccine rates alarmingly have dipped below the threshold for herd immunity.

While Dr. Emmanuel and Mr. Guido acknowledge that the pandemic was a major driver of the falling vaccination rates they lay blame on the persistent decline on three factors that they view as correctable: nonmedical exemptions, our failure to vigorously enforce existing vaccine requirements, and inadequate public health campaigns.

The authors underestimate the lingering effect of the pandemic on parents’ vaccine hesitancy. As a septuagenarian who often hangs out with other septuagenarians I view the rapid development and effectiveness of the COVID vaccine as astounding and a boost for vaccines in general. However, were I much younger I might treat the vaccine’s success with a shrug. After some initial concern, the younger half of the population didn’t seem to see the illness as much of a threat to themselves or their peers. This attitude was reinforced by the fact that few of their peers, including those who were unvaccinated, were getting seriously ill. Despite all the hype, most parents and their children never ended up getting seriously ill.

You can understand why many parents might be quick to toss what you and I consider a successful COVID vaccine onto what they view as a growing pile of vaccines for diseases that in their experience have never sickened or killed anyone they have known.

Let’s be honest: Over the last half century we have produced several generations of parents who have little knowledge and certainly no personal experience with a childhood disease on the order or magnitude of polio. The vaccines that we have developed during their lifetimes have been targeted at diseases such as haemophilus influenzae meningitis that, while serious and anxiety provoking for pediatricians, occur so sporadically that most parents have no personal experience to motivate them to vaccinate their children.

Dr. Emmanuel and Mr. Guido are correct in advocating for the broader elimination of nonmedical exemptions and urging us to find the political will to vigorously enforce the vaccine requirements we have already enacted. I agree that our promotional campaigns need to be more robust. But, this will be a difficult challenge unless we can impress our audience with our straight talk and honesty. We must acknowledge and then explain why all vaccines are not created equal and that some are of more critical importance than others.

We are slowly learning that education isn’t the cure-all for vaccine hesitancy we once thought it was. And using scare tactics can backfire and create dysfunctional anxiety. We must choosing our words and target audience carefully. And ... having the political will to force parents into doing the right thing will be critical if we wish to restore our vaccination rates.

PARIS – All the way back in 1907, The Lancet published an article on a gonorrhea vaccine trial. Today, after continuous research throughout the intervening 110-plus years, scientists may finally have achieved success. Sébastien Fouéré, MD, discussed the details at a press conference that focused on the highlights of the Dermatology Days of Paris conference. Dr. Fouéré is the head of the genital dermatology and sexually transmitted infections unit at Saint-Louis Hospital, Paris.

Twin bacteria

Although the gonorrhea vaccine has long been the subject of research, Dr. Fouéré views 2017 as a turning point. This was when the results of a study led by Helen Petousis-Harris, PhD, were published.

“She tried to formalize the not completely indisputable results published by Cuba, where it seemed there were fewer gonococci in individuals vaccinated against meningococcal group B,” he noted.

Dr. Petousis-Harris, an immunologist, conducted a retrospective case-control study involving 11 clinics in New Zealand. The participants were aged 15-30 years, were eligible to receive the meningococcal B vaccine, and had been diagnosed with gonorrhea, chlamydia, or both. The researchers found that receiving the meningococcal B vaccine in childhood provides around 30% protection against Neisseria gonorrhoeae infections.

“It’s not perhaps a coincidence that a meningococcal B vaccine would be protective against gonorrhea,” Dr. Fouéré pointed out. He considers this protection logical, even expected, insofar as “meningococcus and gonococcus are almost twins.” There is 90% and 100% homology between membrane proteins of the two bacteria.
 

Vaccine is effective

Two retrospective case-control studies confirm that the vaccine is protective. One of the studies, carried out by an Australian team, found that the effectiveness was 32%, quite close to that reported by Petousis-Harris. In the other study, a U.S. team brought to light a dose-response relationship. A partial vaccination series (single serogroup B meningococcal outer membrane vesicle vaccine dose) was 26% effective against gonorrhea, while a complete vaccination series (two MenB-4C doses) was 40% effective.

Prospective studies are in progress, which will provide a higher level of evidence. The ANRS DOXYVAC trial has been underway since January 2021. The participants are men who have sex with men, who are highly exposed to the risk of sexually transmitted infections, and who presented with at least one STI in the year before their participation in the study. “The study is being conducted by Jean-Michel Molina of Saint-Louis Hospital. What they’re trying to do is protect our cohort of pre-exposure prophylaxis patients with meningococcal vaccine,” explained Dr. Fouéré.

Initial findings demonstrated the efficacy of a meningococcal B vaccine in reducing the risk of gonorrhea and the efficacy of doxycycline as preventive intervention for STIs when taken within 72 hours after sexual intercourse. In light of these results, a decision was made at the end of October to discontinue the trial and to recommend providing both interventions to all ANRS DOXYVAC participants. The follow-up of the participants will continue until the end of 2023. The results that led to stopping the study in its current form will be presented in early 2023.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
 

Influenza

Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.

RSV

In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.²

COVID-19

Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.

There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.

If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.³

With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.

Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
 

In summary

Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.

Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
 

In summary

Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
 

Influenza

Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.

RSV

In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.²

COVID-19

Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.

There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.

If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.³

The Ohio measles outbreak continues to expand, with cases now totaling 81 – a 37% increase in the course of just 2 weeks.

The lead health official where the outbreak is occurring said the driving force behind the spread is vaccine hesitancy. Most of the children infected were unvaccinated but were old enough to get the measles, mumps, and rubella (MMR) shot, which is 97% effective at preventing measles.

“I think these are individuals who are making a decision not to protect their children against vaccine-preventable diseases, and some of them are making a specific decision not to use the MMR vaccine,” Columbus Public Health Commissioner Mysheika W. Roberts, MD, told JAMA.

She said that parents’ refusal to vaccinate their children was due to a misconception that the vaccine causes autism.

“We’re sounding the alarm that if your child is of age and not vaccinated, they should get vaccinated ASAP,” Dr. Roberts said, noting that she hasn’t seen that happening more.

Health officials have predicted the outbreak, which started in November, will last at least several months. Measles is so contagious that 9 out of 10 unvaccinated people in a room will become infected if exposed.

All of the infections have been in children. According to the Columbus Public Health measles dashboard, of the 81 confirmed cases:

• 29 children have been hospitalized.
• 22 cases are among children under 1 year old.
• No deaths have been reported.

Dr. Roberts said the hospitalized children have had symptoms including dehydration, diarrhea, and pneumonia. Some have had to go to the intensive care unit.

Measles infection causes a rash and a fever that can spike beyond 104° F. Sometimes, the illness can lead to brain swelling, brain damage, and even death, the CDC says.

One of the most recent cases was an infant too young to be vaccinated who lives 45 miles away from where the outbreak began, the Dayton Daily News reported. That’s the first case in Clark County in more than 20 years. At least 10% of kindergartners’ parents in the region’s elementary schools opted out of vaccines because of religious or moral objections.

“We knew this was coming. It was a matter of when, not if,” Yamini Teegala, MD, chief medical officer at Rocking Horse Community Health Center in Springfield, told the Dayton Daily News.

This is the second measles outbreak this year. Minnesota tallied 22 cases since June in an unrelated outbreak, JAMA reported.

An investigational vaccine against respiratory syncytial virus (RSV) in pregnant women has been shown to help protect infants against severe disease, according to the vaccine’s manufacturer.

Pfizer recently announced that in the course of a randomized, double-blind, placebo-controlled phase 3 study, the vaccine RSVpreF had an almost 82% efficacy against severe RSV infection in infants from birth through the first 90 days of life, according to a company press release.

The vaccine also had a 69% efficacy against severe disease through the first 6 months of life. A total of 7,400 women had received a single dose of 120 mcg RSVpreF in the late second or third trimester of their pregnancy. There were no signs of safety issues for the mothers or infants.

Due to the good results, the enrollment in the study was halted on the recommendation of the study’s Data Monitoring Committee after achieving a primary endpoint. The company plans to apply for marketing authorization to the U.S. Food and Drug Administration by the end of 2022 and to other regulatory agencies in 2023.

“The directness of the strategy, to vaccinate expectant mothers during pregnancy so that their newborn is then later protected, is new and a very interesting approach,” commented Prof. Ortwin Adams, MD, head of virologic diagnostics at the Institute for Virology of the University Hospital of Düsseldorf (Germany) to the Science Media Centre (SMC).

In terms of the RSV vaccination strategy presented, “the unborn child has taken center stage from the outset.” Because the vaccination route is the placental transfer of antibodies from mother to child (“passive immunity”), “... the medical points of contact for this vaccination will be the gynecologists, not the pediatricians,” Dr. Adams said.

“This concept imitates the natural process, since the mother normally passes immune defenses she acquired through infections to the child via the umbilical cord and her breast milk before and after birth. This procedure is long-proven and practiced worldwide, especially in nonindustrialized countries, for a variety of diseases, including tetanus, whooping cough (pertussis), and viral flu (influenza),” explained Markus Rose, MD, PhD, head of Pediatric Pulmonology at the Olgahospital, Stuttgart, Germany.

The development of an RSV vaccine had ground to a halt for many decades: A tragedy in the 1960s set the whole field of research back. Using the model of the first polio vaccine, scientists had manufactured an experimental vaccine with inactivated viruses. However, tests showed that the vaccine did not protect the children vaccinated, but it actually infected them with RSV, they then fell ill, and two children died. Today, potential RSV vaccines are first tested on adults and not on children.
 

Few treatment options

RSV causes seasonal epidemics, can lead to bronchiolitis and pneumonia in infants, and is one of the main causes of hospital stays in young children. Monoclonal antibodies are currently the only preventive option, since there is still no vaccine. Usually, 60%-70% of infants and nearly all children younger than 2 years are infected with RSV, but the virus can also trigger pneumonia in adults.

“RSV infections constitute a major public health challenge: It is the most dangerous respiratory virus for young infants, it is also a threat to the chronically ill and immunocompromised of all ages, and [it] is the second most common cause of death worldwide (after malaria) in young children,” stated Dr. Rose.

Recently, pandemic-related measures (face masks, more intense disinfection) meant that the “normal” RSV infections in healthy adults, which usually progress like a mild cold, were prevented, and mothers were unable to pass on as much RSV immune defense to their children. “This was presumably responsible in part for the massive wave of RSV infections in fall and winter of 2021/22,” explained Dr. Rose.

Thomas Mertens, MD, PhD, chair of the Standing Committee on Vaccination at the Robert Koch Institute (STIKO) and former director of the Institute for Virology at Ulm University Hospital, Germany, also noted: “It would be an important and potentially achievable goal to significantly reduce the incidence rate of hospitalizations. In this respect, RSV poses a significant problem for young children, their parents, and the burden on pediatric clinics.”
 

Final evaluation pending

“I am definitely finding the data interesting, but the original data are needed,” Dr. Mertens said. Once the data are published at a conference or published in a peer-reviewed journal, physicians will be able to better judge the data for themselves, he said.

Dr. Rose characterized the new vaccine as “novel,” including in terms of its composition. Earlier RSV vaccines used the so-called postfusion F protein as their starting point. But it has become known in the meantime that the key to immunogenicity is the continued prefusion state of the apical epitope: Prefusion F-specific memory B cells in adults naturally infected with RSV produce potent neutralizing antibodies.

The new vaccine is bivalent and protects against both RSV A and RSV B.

To date, RSV vaccination directly in young infants have had only had a weak efficacy and were sometimes poorly tolerated. The vaccine presented here is expected to be tested in young adults first, then in school children, then young children.

Through successful vaccination of the entire population, the transfer of RS viruses to young children could be prevented. “To what extent this, or any other RSV vaccine still to be developed on the same basis, will also be effective and well tolerated in young infants is still difficult to assess,” said Dr. Rose.

Dr. Mertens emphasized that all of the study data now needs to be seen as quickly as possible: “This is also a general requirement for transparency from the pharmaceutical companies, which is also rightly criticized.”

Two years ago, when the first COVID-19 vaccines were administered, marked a game-changing moment in the fight against the pandemic. But it also was a significant moment for messenger RNA (mRNA) technology, which up until then had shown promise but had never quite broken through. 

Now, scientists hope to use this technology to develop more vaccines, with those at the University of Pennsylvania hoping to use that technology to pioneer yet another first: a universal flu vaccine that can protect us against all flu types, not just a select few. 

It’s the latest advance in a new age of vaccinology, where vaccines are easier and faster to produce, as well as more flexible and customizable. 

“It’s all about covering the different flavors of flu in a way the current vaccines cannot do,” says Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, who is not involved with the UPenn research. “The mRNA platform is attractive here given its scalability and modularity, where you can mix and match different mRNAs.” 

A recent paper, published in Science, reports successful animal tests of the experimental vaccine, which, like the Pfizer-BioNTech and Moderna COVID vaccines, relies on mRNA. But the idea is not to replace the annual flu shot. It’s to develop a primer that could be administered in childhood, readying the body’s B cells and T cells to react quickly if faced with a flu virus. 

It’s all part of a National Institutes of Health–funded effort to develop a universal flu vaccine, with hopes of heading off future flu pandemics. Annual shots protect against flu subtypes known to spread in humans. But many subtypes circulate in animals, like birds and pigs, and occasionally jump to humans, causing pandemics. 

“The current vaccines provide very little protection against these other subtypes,” says lead study author Scott Hensley, PhD, a professor of microbiology at UPenn. “We set out to make a vaccine that would provide some level of immunity against essentially every influenza subtype we know about.” 

That’s 20 subtypes altogether. The unique properties of mRNA vaccines make immune responses against all those antigens possible, Dr. Hensley says. 

Old-school vaccines introduce a weakened or dead bacteria or virus into the body, but mRNA vaccines use mRNA encoded with a protein from the virus. That’s the “spike” protein for COVID, and for the experimental vaccine, it’s hemagglutinin, the major protein found on the surface of all flu viruses.

Mice and ferrets that had never been exposed to the flu were given the vaccine and produced high levels of antibodies against all 20 flu subtypes. Vaccinated mice exposed to the exact strains in the vaccine stayed pretty healthy, while those exposed to strains not found in the vaccine got sick but recovered quickly and survived. Unvaccinated mice exposed to the flu strain died. 

The vaccine seems to be able to “induce broad immunity against all the different influenza subtypes,” Dr. Hensley says, preventing severe illness if not infection overall. 

Still, whether it could truly stave off a pandemic that hasn’t happened yet is hard to say, Dr. Levy cautions. 

“We are going to need to better learn the molecular rules by which these vaccines protect,” he says.

But the UPenn team is forging ahead, with plans to test their vaccine in human adults in 2023 to determine safety, dosing, and antibody response.

Now, scientists hope to use this technology to develop more vaccines, with those at the University of Pennsylvania hoping to use that technology to pioneer yet another first: a universal flu vaccine that can protect us against all flu types, not just a select few. 

It’s the latest advance in a new age of vaccinology, where vaccines are easier and faster to produce, as well as more flexible and customizable. 

“It’s all about covering the different flavors of flu in a way the current vaccines cannot do,” says Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, who is not involved with the UPenn research. “The mRNA platform is attractive here given its scalability and modularity, where you can mix and match different mRNAs.” 

A recent paper, published in Science, reports successful animal tests of the experimental vaccine, which, like the Pfizer-BioNTech and Moderna COVID vaccines, relies on mRNA. But the idea is not to replace the annual flu shot. It’s to develop a primer that could be administered in childhood, readying the body’s B cells and T cells to react quickly if faced with a flu virus. 

It’s all part of a National Institutes of Health–funded effort to develop a universal flu vaccine, with hopes of heading off future flu pandemics. Annual shots protect against flu subtypes known to spread in humans. But many subtypes circulate in animals, like birds and pigs, and occasionally jump to humans, causing pandemics. 

“The current vaccines provide very little protection against these other subtypes,” says lead study author Scott Hensley, PhD, a professor of microbiology at UPenn. “We set out to make a vaccine that would provide some level of immunity against essentially every influenza subtype we know about.” 

That’s 20 subtypes altogether. The unique properties of mRNA vaccines make immune responses against all those antigens possible, Dr. Hensley says. 

Old-school vaccines introduce a weakened or dead bacteria or virus into the body, but mRNA vaccines use mRNA encoded with a protein from the virus. That’s the “spike” protein for COVID, and for the experimental vaccine, it’s hemagglutinin, the major protein found on the surface of all flu viruses.

Mice and ferrets that had never been exposed to the flu were given the vaccine and produced high levels of antibodies against all 20 flu subtypes. Vaccinated mice exposed to the exact strains in the vaccine stayed pretty healthy, while those exposed to strains not found in the vaccine got sick but recovered quickly and survived. Unvaccinated mice exposed to the flu strain died. 

The vaccine seems to be able to “induce broad immunity against all the different influenza subtypes,” Dr. Hensley says, preventing severe illness if not infection overall. 

Still, whether it could truly stave off a pandemic that hasn’t happened yet is hard to say, Dr. Levy cautions. 

“We are going to need to better learn the molecular rules by which these vaccines protect,” he says.

But the UPenn team is forging ahead, with plans to test their vaccine in human adults in 2023 to determine safety, dosing, and antibody response.
