Vaccines

It’s back to school time, and some may be wondering what the current availability of vaccines may mean and the effects of the ever-changing COVID-19 guidelines on their children’s education and day-to-day experiences as students this year.

Unlike last school year, there are now vaccines available for all over the age of 6 months, and home rapid antigen tests are more readily available. Additionally, many have now been exposed either by infection or vaccination to the virus.

The CDC has removed the recommendations for maintaining cohorts in the K-12 population. This changing landscape along with differing levels of personal risk make it challenging to counsel families about what to expect in terms of COVID this year.

The best defense that we currently have against COVID is the vaccine. Although it seems that many are susceptible to the virus despite the vaccine, those who have been vaccinated are less susceptible to serious disease, including young children.

As older children may be heading to college, it is important

to encourage them to isolate when they have symptoms, even when they test negative for COVID as we would all like to avoid being sick in general.

Additionally, they should pay attention to the COVID risk level in their area and wear masks, particularly when indoors, as the levels increase. College students should have a plan for where they can isolate when not feeling well. 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.
 

Monkeypox

We now have a new health concern for this school year.

Monkeypox has come onto the scene with information changing as rapidly as information previously did for COVID. With this virus, we must particularly counsel those heading away to college to be careful to limit their exposure to this disease.

Dormitories and other congregate settings are high-risk locations for the spread of monkeypox. Particularly, students headed to stay in dormitories should be counseled about avoiding:

• sexual activity with those with lesions consistent with monkeypox;
• sharing eating and drinking utensils; and
• sleeping in the same bed as or sharing bedding or towels with anyone with a diagnosis of or lesions consistent with monkeypox.

Additionally, as with prevention of all infections, it is important to frequently wash hands or use alcohol-based sanitizer before eating, and avoid touching the face after using the restroom.

Guidance for those eligible for vaccines against monkeypox seems to be quickly changing as well.

At the time of this article, CDC guidance recommends the vaccine against monkeypox for:

• those considered to be at high risk for it, including those identified by public health officials as a contact of someone with monkeypox;
• those who are aware that a sexual partner had a diagnosis of monkeypox within the past 2 weeks;
• those with multiple sex partners in the past 2 weeks in an area with known monkeypox; and
• those whose jobs may expose them to monkeypox.

Currently, the CDC recommends the vaccine JYNNEOS, a two-dose vaccine that reaches maximum protection after fourteen days. Ultimately, guidance is likely to continue to quickly change for both COVID-19 and Monkeypox throughout the fall. It is possible that new vaccinations will become available, and families and physicians alike will have many questions.

Primary care offices should ensure that someone is keeping up to date with the latest guidance to share with the office so that physicians may share accurate information with their patients.

Families should be counseled that we anticipate information about monkeypox, particularly related to vaccinations, to continue to change, as it has during all stages of the COVID pandemic.

As always, patients should be reminded to continue regular routine vaccinations, including the annual influenza vaccine.

Pfizer has sent an application to the Food and Drug Administration for emergency use authorization of its updated COVID-19 booster vaccine for the fall of 2022, the company announced on Aug. 22.

The vaccine, which is adapted for the BA.4 and BA.5 Omicron variants, would be meant for ages 12 and older. If authorized by the FDA, the doses could ship as soon as September.

“Having rapidly scaled up production, we are positioned to immediately begin distribution of the bivalent Omicron BA.4/BA.5 boosters, if authorized, to help protect individuals and families as we prepare for potential fall and winter surges,” Albert Bourla, PhD, Pfizer’s chairman and CEO, said in the statement.

Earlier this year, the FDA ordered vaccine makers such as Pfizer and Moderna to update their shots to target BA.4 and BA.5, which are better at escaping immunity from earlier vaccines and previous infections.

The United States has a contract to buy 105 million of the Pfizer doses and 66 million of the Moderna doses, according to The Associated Press. Moderna is expected to file its FDA application soon as well.

The new shots target both the original spike protein on the coronavirus and the spike mutations carried by BA.4 and BA.5. For now, BA.5 is causing 89% of new infections in the United States, followed by BA.4.6 with 6.3% and BA.4 with 4.3%, according to the latest Centers for Disease Control and Prevention data.

There’s no way to tell if BA.5 will still be the dominant strain this winter or if new variant will replace it, the AP reported. But public health officials have supported the updated boosters as a way to target the most recent strains and increase immunity again.

On Aug. 15, Great Britain became the first country to authorize another one of Moderna’s updated vaccines, which adds protection against BA.1, or the original Omicron strain that became dominant in the winter of 2021-2022. European regulators are considering this shot, the AP reported, but the United States opted not to use this version since new Omicron variants have become dominant.

To approve the latest Pfizer shot, the FDA will rely on scientific testing of prior updates to the vaccine, rather than the newest boosters, to decide whether to fast-track the updated shots for fall, the AP reported. This method is like how flu vaccines are updated each year without large studies that take months.

Previously, Pfizer announced results from a study that found the earlier Omicron update significantly boosted antibodies capable of fighting the BA.1 variant and provided some protection against BA.4 and BA.5. The company’s latest FDA application contains that data and animal testing on the newest booster, the AP reported.

Pfizer will start a trial using the BA.4/BA.5 booster in coming weeks to get more data on how well the latest shot works. Moderna has begun a similar study.

The full results from these studies won’t be available before a fall booster campaign, which is why the FDA and public health officials have called for an updated shot to be ready for distribution in September.

“It’s clear that none of these vaccines are going to completely prevent infection,” Rachel Presti, MD, a researcher with the Moderna trial and an infectious diseases specialist at Washington University in St. Louis, told the AP.

But previous studies of variant booster candidates have shown that “you still get a broader immune response giving a variant booster than giving the same booster,” she said.

Researchers in France have discovered monkeypox virus in anal samples of men with no symptoms of the disease, advancing the possibility that asymptomatic carriers may be hidden drivers of the global outbreak.

The findings, published in Annals of Internal Medicine, follow a similar, non–peer-reviewed report from Belgium. Researchers in both studies tested swabs for monkeypox in men who have sex with men. These swabs had been collected for routine STI screening.

It’s unclear whether asymptomatic individuals who test positive for monkeypox can spread the virus, the French team wrote. But if so, public health strategies to vaccinate those with known exposure “may not be sufficient to contain spread.”

In an editorial accompanying their paper, Stuart Isaacs, MD, associate professor at the University of Pennsylvania, Philadelphia, said it “raises the question of whether asymptomatic or subclinical infections are contributing to the current worldwide outbreak.”

Historically, transmission of monkeypox and its close relative, smallpox, was thought to be greatest when a rash was present, Dr. Isaacs wrote. “Long chains of human-to-human transmission were rare” with monkeypox.

That’s changed with the current outbreak, which was first detected in May. On Aug. 17, the World Health Organization reported more than 35,000 cases in 92 countries, with 12 deaths.
 

Research methods

For the French study, researchers conducted polymerase chain reaction tests on 200 anorectal swabs from asymptomatic individuals that had been collected from June 5 to July 11 in order to screen for gonorrhea and chlamydia. Of those, 13 (6.5%) were positive for monkeypox.

During the study period, STI testing had been suspended in individuals with monkeypox symptoms because of safety concerns, the researchers reported.

The research team contacted the 13 monkeypox-positive patients and advised them to limit sexual activity for 21 days following their test and notify recent sexual partners. None reported having developed symptoms, but two subsequently returned to the clinic with symptoms – one had an anal rash and the other a sore throat.

In the Belgian report, posted publicly on June 21 as a preprint, 3 of 224 anal samples collected for STI screening in May tested positive for monkeypox. All three of the men who tested positive said they did not have any symptoms in the weeks before and after the sample was taken.

At follow-up testing, 21-37 days after the initial samples were taken, all patients who had previously tested positive were negative. This was “likely as a consequence of spontaneous clearance of the infection,” the authors of that paper wrote.
 

Clinical implications of findings are uncertain

Monica Gandhi, MD, MPH, a professor of medicine at the University of California, San Francisco, said in an interview that the clinical implications of the findings are uncertain because it’s not known how much viral transmission results from asymptomatic individuals.

Nevertheless, Dr. Gandhi said that “vaccinating all gay men for monkeypox who will accept the vaccine is prudent,” compared with a less aggressive strategy of only vaccinating those with known exposure, which is called ring vaccination. That way, “we can be assured to provide immunity to large swaths of the at-risk population.”

Dr. Gandhi said that movement toward mass vaccination of gay men is occurring in the United States, Canada, Europe, and Australia, despite limited vaccine supply.

She added that, although monkeypox has been concentrated in communities of men who have sex with men, “anyone with multiple sexual partners should be vaccinated given the data.”

However, a WHO official recently cautioned that reports of breakthrough infections in individuals who were vaccinated against monkeypox constitute a reminder that “vaccine is not a silver bullet.”
 

Non-vaccine interventions are also needed

Other experts stressed the need for nonvaccine interventions.

In his editorial, Dr. Isaacs said an “expanded” ring vaccination strategy in communities of high risk is likely needed, but ultimately the outbreak will only be controlled if vaccination is accompanied by other measures such as identifying and isolating cases, making treatment available, and educating individuals about how to reduce their risk.

Aileen Marty, MD, a professor of infectious diseases at Florida International University, Miami, said in an interview that the new evidence makes it “incredibly important” to inform people that they might be infected by a sex partner even if that person does not have telltale lesions.

Dr. Marty said she has been advising men who have sex with men to “reduce or eliminate situations in which they find themselves with multiple anonymous individuals.”

Although most individuals recover from monkeypox, the disease can lead to hospitalization, disfigurement, blindness, and even death, Dr. Marty noted, adding that monkeypox is “absolutely a disease to avoid.”

Authors of the French study reported financial relationships with Gilead Sciences, Viiv Healthcare, MSD, AstraZeneca, Theratechnologies, Janssen Pharmaceuticals, Pfizer, GlaxoSmithKline, and bioMérieux. Dr. Isaacs reported grants from the Department of Veterans Affairs and the National Institutes of Health and royalties from UpToDate. Dr. Gandhi and Dr. Marty reported no relevant financial interests.

Authors of the French study reported financial relationships with Gilead Sciences, Viiv Healthcare, MSD, AstraZeneca, Theratechnologies, Janssen Pharmaceuticals, Pfizer, GlaxoSmithKline, and bioMérieux. Dr. Isaacs reported grants from the Department of Veterans Affairs and the National Institutes of Health and royalties from UpToDate.

A sweeping study of 85,000 infants found no link between mRNA COVID vaccination in pregnancy and greater risk of preterm birth, babies being born small for their gestational age, or stillbirth.

The research team wrote in the BMJ that their reassuring findings – drawn from a registry of all births in Ontario over an 8-month period – “can inform evidence-based decision-making” about COVID vaccination during pregnancy.

Previous research has found that pregnant patients are at higher risk of severe complications and death if they become infected with COVID and that vaccination before or during pregnancy prevents such outcomes and reduces the risk of newborn infection, noted Jeffrey Ecker, chief of obstetrics and gynecology at Massachusetts General Hospital, Boston.

This new study “adds to a growing body of information arguing clearly and reassuringly that vaccination during pregnancy is not associated with complications during pregnancy,” said Dr. Ecker, who was not involved in the new study.

He added that it “should help obstetric providers further reassure those who are hesitant that vaccination is safe and best both for the pregnant patient and their pregnancy.”
 

Methods and results

For the new study, researchers tapped a provincial registry of all live and stillborn infants with a gestational age of at least 20 weeks or birth weight of at least 500 g. Unique health card numbers were used to link birth records to a database of COVID vaccinations.

Of 85,162 infants born from May through December of 2021, 43,099 (50.6%) were born to individuals who received at least one vaccine dose during pregnancy. Among those, 99.7% received an mRNA vaccine such as Pfizer-BioNTech or Moderna.

Vaccination during pregnancy was not associated with greater risk of overall preterm birth (6.5% among vaccinated individuals versus 6.9% among unvaccinated; hazard ratio, 1.02; 95% confidence interval, 0.96-1.08), spontaneous preterm birth (3.7% versus 4.4%; hazard ratio, 0.96; 95% CI, 0.90-1.03) or very preterm birth (0.59% versus 0.89%; hazard ratio, 0.80; 95% CI, 0.67-0.95).

Likewise, no increase was observed in the risk of an infant being small for gestational age at birth (9.1% versus 9.2%; hazard ratio, 0.98; 95% CI, 0.93-1.03).

The researchers observed a reduction in the risk of stillbirth, even after adjusting for potential confounders. Stillbirths occurred in 0.25% of vaccinated individuals, compared with 0.44% of unvaccinated individuals (hazard ratio, 0.65; 95% CI, 0.51-0.84).

A reduced risk of stillbirth – albeit to a smaller degree – was also found in a Scandinavian registry study that included 28,506 babies born to individuals who were vaccinated during pregnancy.

“Collectively, the findings from these two studies are reassuring and are consistent with no increased risk of stillbirth after COVID-19 vaccination during pregnancy. In contrast, COVID-19 disease during pregnancy has been associated with an increased risk of stillbirth,” the researchers wrote.

Findings did not vary by which mRNA vaccine a mother received, the number of doses she received, or the trimester in which a vaccine was given, the researchers reported.
 

Stillbirth findings will be ‘very reassuring’ for patients

The lead investigator, Deshayne Fell, PhD, said in an interview, the fact that the study comprised the entire population of pregnant people in Ontario during the study period “increases our confidence” about the validity and relevance of the findings for other geographic settings.

Dr. Fell, an associate professor in epidemiology and public health at the University of Ottawa and a scientist at the Children’s Hospital of Eastern Ontario Research Institute, Ottawa, said the evaluation of stillbirth in particular, “a rare but devastating outcome,” will be “very reassuring and useful for clinical counseling.”

A limitation cited by the research team included a lack of data on vaccination prior to pregnancy.

In the new study, Dr, Ecker said, “Though the investigators were able to adjust for many variables they cannot be certain that some unmeasured variable that, accordingly, was not adjusted for does not hide a small risk. This seems very unlikely, however.”

The Canadian research team said similar studies of non-mRNA COVID vaccines “should be a research priority.” However, such studies are not underway in Canada, where only mRNA vaccines are used in pregnancy, Dr. Fell said.

This study was supported by the Public Health Agency of Canada.

Dr. Fell and Dr. Ecker reported no competing financial interests.

My group in Rochester, N.Y., examined the current pneumococcal serotypes causing AOM in children. From our data, we can determine the PCV13 vaccine types that escape prevention and cause AOM and understand what effect to expect from the new pneumococcal conjugate vaccines (PCVs) that will be coming soon. There are limited data from middle ear fluid (MEF) cultures on which to base such analyses. Tympanocentesis is the preferred method for securing MEF for culture and our group is unique in providing such data to the Centers for Disease Control and publishing our results on a periodic basis to inform clinicians.

Pneumococci are the second most common cause of acute otitis media (AOM) since the introduction of pneumococcal conjugate vaccines (PCVs) more than 2 decades ago.^1,2 Pneumococcal AOM causes more severe acute disease and more often causes suppurative complications than Haemophilus influenzae, which is the most common cause of AOM. Prevention of pneumococcal AOM will be a highly relevant contributor to cost-effectiveness analyses for the anticipated introduction of PCV15 (Merck) and PCV20 (Pfizer). Both PCV15 and PCV20 have been licensed for adult use; PCV15 licensure for infants and children occurred in June 2022 for invasive pneumococcal disease and is anticipated in the near future for PCV20. They are improvements over PCV13 because they add serotypes that cause invasive pneumococcal diseases, although less so for prevention of AOM, on the basis of our data.

Nasopharyngeal colonization is a necessary pathogenic step in progression to pneumococcal disease. However, not all strains of pneumococci expressing different capsular serotypes are equally virulent and likely to cause disease. In PCV-vaccinated populations, vaccine pressure and antibiotic resistance drive PCV serotype replacement with nonvaccine serotypes (NVTs), gradually reducing the net effectiveness of the vaccines. Therefore, knowledge of prevalent NVTs colonizing the nasopharynx identifies future pneumococcal serotypes most likely to emerge as pathogenic.

We published an effectiveness study of PCV13.³ A relative reduction of 86% in AOM caused by strains expressing PCV13 serotypes was observed in the first few years after PCV13 introduction. The greatest reduction in MEF samples was in serotype 19A, with a relative reduction of 91%. However, over time the vaccine type efficacy of PCV13 against MEF-positive pneumococcal AOM has eroded. There was no clear efficacy against serotype 3, and we still observed cases of serotype 19A and 19F. PCV13 vaccine failures have been even more frequent in Europe (nearly 30% of pneumococcal AOM in Europe is caused by vaccine serotypes) than our data indicate, where about 10% of AOM is caused by PCV13 serotypes.

In our most recent publication covering 2015-2019, we described results from 589 children, aged 6-36 months, from whom we collected 2,042 nasopharyngeal samples.^2,4 During AOM, 495 MEF samples from 319 AOM-infected children were collected (during bilateral infections, tympanocentesis was performed in both ears). Whether bacteria were isolated was based per AOM case, not per tap. The average age of children with AOM was 15 months (range 6-31 months). The three most prevalent nasopharyngeal pneumococcal serotypes were 35B, 23B, and 15B/C. Serotype 35B was the most common at AOM visits in both the nasopharynx and MEF samples followed by serotype 15B/C. Nonsusceptibility among pneumococci to penicillin, azithromycin, and multiple other antibiotics was high. Increasing resistance to ceftriaxone was also observed.

Based on our results, if PCV15 (PCV13 + 22F and 33F) effectiveness is identical to PCV13 for the included serotypes and 100% efficacy for the added serotypes is presumed, PCV15 will reduce pneumococcal AOMs by 8%, pneumococcal nasopharyngeal colonization events at onset of AOM by 6%, and pneumococcal nasopharyngeal colonization events during health by 3%. As for the projected reductions brought about by PCV20 (PCV15 + 8, 10A, 11A, 12F, and 15B), presuming serotype 15B is efficacious against serotype 15C and 100% efficacy for the added serotypes, PCV20 will reduce pneumococcal AOMs by 22%, pneumococcal nasopharyngeal colonization events at onset of AOM by 20%, and pneumococcal nasopharyngeal colonization events during health by 3% (Figure).

The CDC estimated that, in 2004, pneumococcal disease in the United States caused 4 million illness episodes, 22,000 deaths, 445,000 hospitalizations, 774,000 emergency department visits, 5 million outpatient visits, and 4.1 million outpatient antibiotic prescriptions. Direct medical costs totaled $3.5 billion. Pneumonia (866,000 cases) accounted for 22% of all cases and 72% of pneumococcal costs. AOM and sinusitis (1.5 million cases each) composed 75% of cases and 16% of direct medical costs.⁵ However, if indirect costs are taken into account, such as work loss by parents of young children, the cost of pneumococcal disease caused by AOM alone may exceed $6 billion annually⁶ and become dominant in the cost-effectiveness analysis in high-income countries.

Despite widespread use of PCV13, Pneumococcus has shown its resilience under vaccine pressure such that the organism remains a very common AOM pathogen. All-cause AOM has declined modestly and pneumococcal AOM caused by the specific serotypes in PCVs has declined dramatically since the introduction of PCVs. However, the burden of pneumococcal AOM disease is still considerable.

The notion that strains expressing serotypes that were not included in PCV7 were less virulent was proven wrong within a few years after introduction of PCV7, with the emergence of strains expressing serotype 19A, and others. The same cycle occurred after introduction of PCV13. It appears to take about 4 years after introduction of a PCV before peak effectiveness is achieved – which then begins to erode with emergence of NVTs. First, the NVTs are observed to colonize the nasopharynx as commensals and then from among those strains new disease-causing strains emerge.

At the most recent meeting of the International Society of Pneumococci and Pneumococcal Diseases in Toronto in June, many presentations focused on the fact that PCVs elicit highly effective protective serotype-specific antibodies to the capsular polysaccharides of included types. However, 100 serotypes are known. The limitations of PCVs are becoming increasingly apparent. They are costly and consume a large portion of the Vaccines for Children budget. Children in the developing world remain largely unvaccinated because of the high cost. NVTs that have emerged to cause disease vary by country, vary by adult vs. pediatric populations, and are dynamically changing year to year. Forthcoming PCVs of 15 and 20 serotypes will be even more costly than PCV13, will not include many newly emerged serotypes, and will probably likewise encounter “serotype replacement” because of high immune evasion by pneumococci.

When Merck and Pfizer made their decisions on serotype composition for PCV15 and PCV20, respectively, they were based on available data at the time regarding predominant serotypes causing invasive pneumococcal disease in countries that had the best data and would be the market for their products. However, from the time of the decision to licensure of vaccine is many years, and during that time the pneumococcal serotypes have changed, more so for AOM, and I predict more change will occur in the future.

In the past 3 years, Dr. Pichichero has received honoraria from Merck to attend 1-day consulting meetings and his institution has received investigator-initiated research grants to study aspects of PCV15. In the past 3 years, he was reimbursed for expenses to attend the ISPPD meeting in Toronto to present a poster on potential efficacy of PCV20 to prevent complicated AOM.

PCV13 vaccine failures have been even more frequent in Europe (nearly 30% of pneumococcal AOM in Europe is caused by vaccine serotypes) than our data indicate, where about 10% of AOM is caused by PCV13 serotypes.

In our most recent publication covering 2015-2019, we described results from 589 children, aged 6-36 months, from whom we collected 2,042 nasopharyngeal samples.^2,4 During AOM, 495 MEF samples from 319 AOM-infected children were collected (during bilateral infections, tympanocentesis was performed in both ears). Whether bacteria were isolated was based per AOM case, not per tap. The average age of children with AOM was 15 months (range 6-31 months). The three most prevalent nasopharyngeal pneumococcal serotypes were 35B, 23B, and 15B/C. Serotype 35B was the most common at AOM visits in both the nasopharynx and MEF samples followed by serotype 15B/C. Nonsusceptibility among pneumococci to penicillin, azithromycin, and multiple other antibiotics was high. Increasing resistance to ceftriaxone was also observed.

Based on our results, if PCV15 (PCV13 + 22F and 33F) effectiveness is identical to PCV13 for the included serotypes and 100% efficacy for the added serotypes is presumed, PCV15 will reduce pneumococcal AOMs by 8%, pneumococcal nasopharyngeal colonization events at onset of AOM by 6%, and pneumococcal nasopharyngeal colonization events during health by 3%. As for the projected reductions brought about by PCV20 (PCV15 + 8, 10A, 11A, 12F, and 15B), presuming serotype 15B is efficacious against serotype 15C and 100% efficacy for the added serotypes, PCV20 will reduce pneumococcal AOMs by 22%, pneumococcal nasopharyngeal colonization events at onset of AOM by 20%, and pneumococcal nasopharyngeal colonization events during health by 3% (Figure).

The CDC estimated that, in 2004, pneumococcal disease in the United States caused 4 million illness episodes, 22,000 deaths, 445,000 hospitalizations, 774,000 emergency department visits, 5 million outpatient visits, and 4.1 million outpatient antibiotic prescriptions. Direct medical costs totaled $3.5 billion. Pneumonia (866,000 cases) accounted for 22% of all cases and 72% of pneumococcal costs. AOM and sinusitis (1.5 million cases each) composed 75% of cases and 16% of direct medical costs.⁵ However, if indirect costs are taken into account, such as work loss by parents of young children, the cost of pneumococcal disease caused by AOM alone may exceed $6 billion annually⁶ and become dominant in the cost-effectiveness analysis in high-income countries.

Despite widespread use of PCV13, Pneumococcus has shown its resilience under vaccine pressure such that the organism remains a very common AOM pathogen. All-cause AOM has declined modestly and pneumococcal AOM caused by the specific serotypes in PCVs has declined dramatically since the introduction of PCVs. However, the burden of pneumococcal AOM disease is still considerable.

The notion that strains expressing serotypes that were not included in PCV7 were less virulent was proven wrong within a few years after introduction of PCV7, with the emergence of strains expressing serotype 19A, and others. The same cycle occurred after introduction of PCV13. It appears to take about 4 years after introduction of a PCV before peak effectiveness is achieved – which then begins to erode with emergence of NVTs. First, the NVTs are observed to colonize the nasopharynx as commensals and then from among those strains new disease-causing strains emerge.

At the most recent meeting of the International Society of Pneumococci and Pneumococcal Diseases in Toronto in June, many presentations focused on the fact that PCVs elicit highly effective protective serotype-specific antibodies to the capsular polysaccharides of included types. However, 100 serotypes are known. The limitations of PCVs are becoming increasingly apparent. They are costly and consume a large portion of the Vaccines for Children budget. Children in the developing world remain largely unvaccinated because of the high cost. NVTs that have emerged to cause disease vary by country, vary by adult vs. pediatric populations, and are dynamically changing year to year. Forthcoming PCVs of 15 and 20 serotypes will be even more costly than PCV13, will not include many newly emerged serotypes, and will probably likewise encounter “serotype replacement” because of high immune evasion by pneumococci.

When Merck and Pfizer made their decisions on serotype composition for PCV15 and PCV20, respectively, they were based on available data at the time regarding predominant serotypes causing invasive pneumococcal disease in countries that had the best data and would be the market for their products. However, from the time of the decision to licensure of vaccine is many years, and during that time the pneumococcal serotypes have changed, more so for AOM, and I predict more change will occur in the future.

In the past 3 years, Dr. Pichichero has received honoraria from Merck to attend 1-day consulting meetings and his institution has received investigator-initiated research grants to study aspects of PCV15. In the past 3 years, he was reimbursed for expenses to attend the ISPPD meeting in Toronto to present a poster on potential efficacy of PCV20 to prevent complicated AOM.

Dr. Pichichero is a specialist in pediatric infectious diseases, Center for Infectious Diseases and Immunology, and director of the Research Institute, at Rochester (N.Y.) General Hospital.

New York City is closing 10 city-run sites where children younger than 5 could get the COVID-19 vaccine, with three of those sites transitioning to administer the monkeypox vaccine.

The city health department said demand for children’s COVID vaccines had been on the downswing at the clinics, which opened in late June. Meanwhile, monkeypox cases have increased, with the city declaring it a public health emergency July 30.

“We always planned to transition vaccination for very young children to providers,” the city’s health department said in a statement, according to Spectrum News NY1. “Due to the ongoing monkeypox emergency, we transitioned some of these sites to administer monkeypox vaccine.”

All the COVID vaccine sites for children will close by Aug. 14, Spectrum News NY1 said. It’s unclear if the other sites will transition to monkeypox vaccine.

No appointments for children’s COVID vaccinations had to be canceled, the city said. The plan is that children now needing the COVID vaccine can go to doctors, pharmacies, or the health department clinics.

Manhattan City Councilwoman Gale Brewer urged the health department to keep the kids’ COVID vaccine sites open through the fall.

“I strongly urge you to maintain these family-friendly sites, at least until mid-September so that children who are going to day care and school can get vaccinated,” Brewer wrote. City schools open Sept. 8

Ms. Brewer noted that the city-run sites administered the Moderna vaccines, while many doctors and neighborhood health clinics use the Pfizer vaccine. That could be a problem for a child that had not finished the Moderna regimen or for families that prefer Moderna.

According to the city health department, 2,130 people in New York City had tested positive for monkeypox as of Aug. 12.

On Friday, the city announced 9,000 additional monkeypox vaccines would be made available the morning of Aug. 13.

More than 60% of Americans older than age 50, and nearly 70% of those older than 65, say they intend to roll up their sleeves to prevent COVID-19 in the fall of 2022.

That finding comes from a new poll by researchers at the University of Michigan, Ann Arbor, who also report that when it comes to the shots, people appear to be putting more trust in their health care professionals than in public health authorities.

“When you are a doctor, you are a trusted source of medical information,” said Preeti Malani, MD, MSJ, an infectious disease specialist at the University of Michigan. “Use the ongoing conversation with your patient as an opportunity to answer their questions and counter any confusion.”

The vaccination campaign appears to be having a rub-off effect, too. More people say they’re likely to receive vaccines and boosters for other infections, such as flu, if they have already been vaccinated and boosted against COVID-19.
 

Inside the poll

Dr. Malani and her colleagues, who published their findings on the National Poll on Healthy Aging’s website, asked 1,024 adults older than 50 about their attitudes on COVID-19 vaccinations and their history of receiving the injections. The questions covered topics including whether the individual had contracted COVID, COVID vaccine doses, and the prevalence of a health care clinician’s opinion on vaccines and boosters. The poll was conducted July 21-26.

The researchers chose the age range of 50-65 years because this group is an important population for new booster shots that target specific variants of the SARS-CoV-2 virus that causes COVID-19.

Only 19% of people aged 50-64 and 44% of those older than 65 said they had received both their first and second COVID-19 booster shots. What’s more, 17% of people said they had not received any doses of a COVID-19 vaccine.

The vast majority (77%) of respondents said their clinician’s recommendations were “very important” or “somewhat important” in their decision to receive the vaccine. 

Dr. Malani said that in her practice, patients have expressed hesitation about COVID-19 vaccines because of concerns about the potential side effects of the shots.

Monica Gandhi, MD, MPH, professor of medicine at the University of California, San Francisco, noted that Americans now appear to trust their physicians more than public health authorities such as the U.S. Centers for Disease Control and Prevention when it comes to COVID-19.

“More people are trusting their providers’ opinions [more] than the CDC or other public health agencies. That speaks volumes to me,” Dr. Gandhi said.

Among the more surprising findings of the poll, according to the researchers, was the number of people who said they had yet to contract COVID-19: 50% of those aged 50-64, and 69% of those older than 65. (Another 12% of those aged 50-64 said they were unsure if they’d ever had the infection.)

Dr. Malani said she hoped future studies would explore in depth the people who remain uninfected with COVID-19.

“We focus a lot on the science of COVID,” she said. “But we need to turn our attention to the behavioral aspects and how to address them.”

New York City veterinarian Erin Kulick used to be a weekend warrior. Only 2½ years ago, the 38-year-old new mother played ultimate Frisbee and flag football with friends. She went for regular 30-minute runs to burn off stress.

Now, Dr. Kulick is usually so exhausted, she can’t walk nonstop for 15 minutes. She recently tried to take her 4-year-old son, Cooper, to the American Museum of Natural History for his first visit, but ended up on a bench outside the museum, sobbing in the rain, because she couldn’t even get through the first hurdle of standing in line. “I just wanted to be there with my kid,” she said.

Dr. Kulick got sick with COVID-19 at the start of the pandemic in March 2020, 9 months before the first vaccine would be approved. Now she is among the estimated one in five infected Americans, or 19%, whose symptoms developed into long COVID.

Dr. Kulick also is now vaccinated and boosted. Had a vaccine been available sooner, could it have protected her from long COVID?

Evidence is starting to show it’s likely.

“The best way not to have long COVID is not to have COVID at all,” said Leora Horwitz, MD, a professor of population health and medicine at New York University. “To the extent that vaccination can prevent you from getting COVID at all, then it helps to reduce long COVID.”

And just as vaccines reduce the risk of severe disease, hospitalization, and death, they also seem to reduce the risk of long COVID if people do get breakthrough infections. People with more serious initial illness appear more likely to have prolonged symptoms, but those with milder disease can certainly get it, too.

“You’re more likely to have long COVID with more severe disease, and we have ample evidence that vaccination reduces the severity of disease,” Dr. Horwitz said. “We also now have quite a lot of evidence that vaccination does reduce your risk of long COVID – probably because it reduces your risk of severe disease.”

There is little consensus about how much vaccines can lower the risk of long-term COVID symptoms, but several studies suggest that number lies anywhere from 15% to more than 80%.

That might seem like a big variation, but infectious disease experts argue that trying to interpret the gap isn’t as important as noticing what’s consistent across all these studies: “Vaccines do offer some protection, but it’s incomplete,” said Ziyad Al-Aly, MD, chief of research and development at the Veterans Affairs St. Louis Health Care System. Dr. Al-Aly, who has led several large studies on long COVID, said focusing on the fact that vaccines do offer some protection is a much better public health message than looking at the different levels of risk.

“Vaccines do a miraculous job for what they were designed to do,” said Dr. Al-Aly. “Vaccines were designed to reduce the risk of hospitalization ... and for that, vaccines are still holding up, even with all the changes in the virus.”

Still, Elena Azzolini, MD, PhD, head of the Humanitas Research Hospital’s vaccination center in Milan, thinks some studies may have underestimated the level of long COVID protection from vaccines because of limits in the study methods, such as not including enough women, who are more affected by long COVID. Her recent study, which looked at 2,560 health care professionals working in nine Italian centers from March 2020 to April 2022, focused on the risk for healthy women and men in their 20s to their 70s.

In the paper, Dr. Azzolini and associates reported that two or three doses of vaccine reduced the risk of hospitalization from COVID-19 from 42% among those who are unvaccinated to 16%-17%. In other words, they found unvaccinated people in the study were nearly three times as likely to have serious symptoms for longer than 4 weeks.

But Dr. Azzolini and Dr. Al-Aly still say that, even for the vaccinated, as long as COVID is around, masks are necessary. That’s because current vaccines don’t do enough to reduce transmission, said Dr. Al-Aly. “The only way that can really help [stop] transmission is covering our nose and mouth with a mask.”
 

How vaccinations affect people who already have long COVID

Some long COVID patients have said they got better after they get boosted, while some say they’re getting worse, said Dr. Horwitz, who is also a lead investigator at the National Institutes of Health’s flagship RECOVER program, a 4-year research project to study long COVID across the United States. (The NIH is still recruiting volunteers for these studies, which are also open to people who have never had COVID.)

One study published in the British Medical Journal analyzed survey data of more than 28,000 people infected with COVID in the United Kingdom and found a 13% reduction in long-term symptoms after a first dose of the vaccine, although it was unclear from the data if the improvement was sustained.

A second dose was associated with another 8% improvement over a 2-month period. “It’s reassuring that we see an average modest improvement in symptoms, not an average worsening in symptoms,” said Daniel Ayoubkhani, principal statistician at the U.K. Office for National Statistics and lead author of the study. Of course, the experience will differ among different people.

“It doesn’t appear that vaccination is the silver bullet that’s going to eradicate long COVID,” he said, but evidence from multiple studies suggests vaccines may help people with long-term symptoms.

Akiko Iwasaki, PhD, an immunobiologist at Yale University, New Haven, Conn., told a White House summit in July that one of the best ways to prevent long COVID is to develop the next generation of vaccines that also prevent milder cases by blocking transmission in the first place.

Back in New York, Dr. Kulick is now triple vaccinated. She’s due for a fourth dose soon but admits she’s “terrified every time” that she’s going to get sicker.

In her Facebook support group for long COVID, she reads that most people with prolonged symptoms handle it well. She has also noticed some of her symptoms eased after her first two doses of vaccine.

Since being diagnosed, Dr. Kulick learned she has a genetic condition, Ehlers-Danlos syndrome, which affects connective tissues that support skin, joints, organs, and blood vessels, and which her doctors say may have made her more prone to long COVID. She’s also being screened for autoimmune diseases, but for now, the only relief she has found has come from long COVID physical therapy, changes to her diet, and integrative medicine.

Dr. Kulick is still trying to figure out how she can get better while keeping her long hours at her veterinary job – and her health benefits. She is thankful her husband is a devoted caregiver to their son and a professional jazz musician with a schedule that allows for some flexibility.

“But it’s really hard when every week feels like I’ve run a marathon,” she said. “I can barely make it through.”

New York City veterinarian Erin Kulick used to be a weekend warrior. Only 2½ years ago, the 38-year-old new mother played ultimate Frisbee and flag football with friends. She went for regular 30-minute runs to burn off stress.

Now, Dr. Kulick is usually so exhausted, she can’t walk nonstop for 15 minutes. She recently tried to take her 4-year-old son, Cooper, to the American Museum of Natural History for his first visit, but ended up on a bench outside the museum, sobbing in the rain, because she couldn’t even get through the first hurdle of standing in line. “I just wanted to be there with my kid,” she said.

Dr. Kulick got sick with COVID-19 at the start of the pandemic in March 2020, 9 months before the first vaccine would be approved. Now she is among the estimated one in five infected Americans, or 19%, whose symptoms developed into long COVID.

Dr. Kulick also is now vaccinated and boosted. Had a vaccine been available sooner, could it have protected her from long COVID?

Evidence is starting to show it’s likely.

“The best way not to have long COVID is not to have COVID at all,” said Leora Horwitz, MD, a professor of population health and medicine at New York University. “To the extent that vaccination can prevent you from getting COVID at all, then it helps to reduce long COVID.”

And just as vaccines reduce the risk of severe disease, hospitalization, and death, they also seem to reduce the risk of long COVID if people do get breakthrough infections. People with more serious initial illness appear more likely to have prolonged symptoms, but those with milder disease can certainly get it, too.

“You’re more likely to have long COVID with more severe disease, and we have ample evidence that vaccination reduces the severity of disease,” Dr. Horwitz said. “We also now have quite a lot of evidence that vaccination does reduce your risk of long COVID – probably because it reduces your risk of severe disease.”

There is little consensus about how much vaccines can lower the risk of long-term COVID symptoms, but several studies suggest that number lies anywhere from 15% to more than 80%.

That might seem like a big variation, but infectious disease experts argue that trying to interpret the gap isn’t as important as noticing what’s consistent across all these studies: “Vaccines do offer some protection, but it’s incomplete,” said Ziyad Al-Aly, MD, chief of research and development at the Veterans Affairs St. Louis Health Care System. Dr. Al-Aly, who has led several large studies on long COVID, said focusing on the fact that vaccines do offer some protection is a much better public health message than looking at the different levels of risk.

“Vaccines do a miraculous job for what they were designed to do,” said Dr. Al-Aly. “Vaccines were designed to reduce the risk of hospitalization ... and for that, vaccines are still holding up, even with all the changes in the virus.”

Still, Elena Azzolini, MD, PhD, head of the Humanitas Research Hospital’s vaccination center in Milan, thinks some studies may have underestimated the level of long COVID protection from vaccines because of limits in the study methods, such as not including enough women, who are more affected by long COVID. Her recent study, which looked at 2,560 health care professionals working in nine Italian centers from March 2020 to April 2022, focused on the risk for healthy women and men in their 20s to their 70s.

In the paper, Dr. Azzolini and associates reported that two or three doses of vaccine reduced the risk of hospitalization from COVID-19 from 42% among those who are unvaccinated to 16%-17%. In other words, they found unvaccinated people in the study were nearly three times as likely to have serious symptoms for longer than 4 weeks.

But Dr. Azzolini and Dr. Al-Aly still say that, even for the vaccinated, as long as COVID is around, masks are necessary. That’s because current vaccines don’t do enough to reduce transmission, said Dr. Al-Aly. “The only way that can really help [stop] transmission is covering our nose and mouth with a mask.”
 

How vaccinations affect people who already have long COVID

Some long COVID patients have said they got better after they get boosted, while some say they’re getting worse, said Dr. Horwitz, who is also a lead investigator at the National Institutes of Health’s flagship RECOVER program, a 4-year research project to study long COVID across the United States. (The NIH is still recruiting volunteers for these studies, which are also open to people who have never had COVID.)

One study published in the British Medical Journal analyzed survey data of more than 28,000 people infected with COVID in the United Kingdom and found a 13% reduction in long-term symptoms after a first dose of the vaccine, although it was unclear from the data if the improvement was sustained.

A second dose was associated with another 8% improvement over a 2-month period. “It’s reassuring that we see an average modest improvement in symptoms, not an average worsening in symptoms,” said Daniel Ayoubkhani, principal statistician at the U.K. Office for National Statistics and lead author of the study. Of course, the experience will differ among different people.

“It doesn’t appear that vaccination is the silver bullet that’s going to eradicate long COVID,” he said, but evidence from multiple studies suggests vaccines may help people with long-term symptoms.

Akiko Iwasaki, PhD, an immunobiologist at Yale University, New Haven, Conn., told a White House summit in July that one of the best ways to prevent long COVID is to develop the next generation of vaccines that also prevent milder cases by blocking transmission in the first place.

Back in New York, Dr. Kulick is now triple vaccinated. She’s due for a fourth dose soon but admits she’s “terrified every time” that she’s going to get sicker.

In her Facebook support group for long COVID, she reads that most people with prolonged symptoms handle it well. She has also noticed some of her symptoms eased after her first two doses of vaccine.

Since being diagnosed, Dr. Kulick learned she has a genetic condition, Ehlers-Danlos syndrome, which affects connective tissues that support skin, joints, organs, and blood vessels, and which her doctors say may have made her more prone to long COVID. She’s also being screened for autoimmune diseases, but for now, the only relief she has found has come from long COVID physical therapy, changes to her diet, and integrative medicine.

Dr. Kulick is still trying to figure out how she can get better while keeping her long hours at her veterinary job – and her health benefits. She is thankful her husband is a devoted caregiver to their son and a professional jazz musician with a schedule that allows for some flexibility.

“But it’s really hard when every week feels like I’ve run a marathon,” she said. “I can barely make it through.”
