Vaccines

A fourth shot of the COVID-19 vaccine boosts antibodies but doesn’t provide enough protection to prevent infections from the Omicron variant, according to new research at an Israeli hospital.

The preliminary results, released on Jan. 17, challenge the idea of giving a second booster dose to slow the spread of the coronavirus, according to USA Today.

“Despite increased antibody levels, the fourth vaccine only offers a partial defense against the virus,” Gili Regev-Yochay, MD, director of the hospital’s infection prevention and control units, told reporters.

“The vaccines, which were more effective against previous variants, offer less protection versus Omicron,” she said.

In a clinical trial, 274 medical workers at Sheba Medical Center near Tel Aviv received a fourth vaccine dose in December – 154 got the Pfizer vaccine and 120 got the Moderna vaccine – after previously getting three Pfizer shots.

Both groups received a boost in antibodies that was “slightly higher” than after the third shot, Dr. Regev-Yochay said. But when compared with a control group that didn’t receive the fourth dose, the extra boost didn’t prevent the spread of Omicron.

“We see many infected with Omicron who received the fourth dose,” Dr. Regev-Yochay said. “Granted, a bit less than in the control group, but still a lot of infections.”

Some public health officials in Israel say the campaign for fourth doses is still worthwhile, according to The Times of Israel. The vaccine still works well against the Alpha and Delta variants, Dr. Regev-Yochay said, and a fourth shot should go to older adults and those who face higher risks for severe COVID-19.

Hours after releasing the preliminary results, Sheba Medical Center published a statement calling for “continuing the vaccination drive for risk groups at this time, even though the vaccine doesn’t provide optimal protection against getting infected with the variant.” News outlets reported that the hospital was pressured into issuing the statement after Israel’s Health Ministry didn’t like the release of the early study results, The Times of Israel reported.

The second booster “returns the level of antibodies to what it was at the beginning of the third booster,” Nachman Ash, MD, director of Israel’s Health Ministry, told Channel 13 TV in Israel, according to The Associated Press.

“That has great importance, especially among the older population,” he said.

As of Sunday, more than 500,000 people in Israel had received fourth doses since the country began offering them last month to medical workers, immunocompromised patients, and people ages 60 years and older, the AP reported. At the same time, the country has faced a recent coronavirus surge that has led to record-breaking numbers of cases and rising hospitalizations.

On Tuesday, the Israeli government said it would shorten the mandatory quarantine period from 7 days to 5 days, the AP reported.

“This decision will enable us to continue safeguarding public health on the one hand and to keep the economy going at this time on the other, even though it is difficult, so that we can get through this wave safely,” Prime Minister Naftali Bennett said.

The Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices has now recommended using Sanofi’s dengue vaccine, Dengvaxia, in the United States, with specific restrictions. The vaccine is only to be used for children aged 9-16 who live in endemic areas and who have evidence with a specific diagnostic test of prior dengue infection.

Dengue is a mosquito-borne virus found throughout the world, primarily in tropical or subtropical climates. Cases had steadily been increasing to 5.2 million in 2019, and the geographic distribution of cases is broadening with climate change and urbanization. About half of the world’s population is now at risk.

The dengue virus has four serotypes. The first infection may be mild or asymptomatic, but the second one can be life-threatening because of a phenomenon called antibody-dependent enhancement.

The lead author of the new recommendations is Gabriela Paz-Bailey, MD, PhD, division of vector-borne diseases, dengue branch, CDC. She told this news organization that, during the second infection, when there are “low levels of antibodies from that first infection, the antibodies help the virus get inside the cells. There the virus is not killed, and that results in increased viral load, and then that can result in more severe disease and the plasma leakage” syndrome, which can lead to shock, severe bleeding, and organ failure. The death rate for severe dengue is up to 13%.

Previous infection with Zika virus, common in the same areas where dengue is endemic, can also increase the risk for symptomatic and severe dengue for subsequent infections.

In the United States, Puerto Rico is the main focus of control efforts because 95% of domestic dengue cases originate there – almost 30,000 cases between 2010 and 2020, with 11,000 cases and 4,000 hospitalizations occurring in children between the ages of 10 and 19.

Because Aedes aegypti, the primary mosquito vector transmitting dengue, is resistant to all commonly used insecticides in Puerto Rico, preventive efforts have shifted from insecticides to vaccination.
 

Antibody tests prevaccination

The main concern with the Sanofi’s dengue vaccine is that it could act as an asymptomatic primary dengue infection, in effect priming the body for a severe reaction from antibody-dependent enhancement with a subsequent infection. That is why it’s critical that the vaccine only be given to children with evidence of prior disease.

Dr. Paz-Bailey said: “The CDC came up with recommendations of what the performance of the test used for prevaccination screening should be. And it was 98% specificity and 75% sensitivity. ... But no test by itself was found to have a specificity of 98%, and this is why we’re recommending the two-test algorithm,” in which two different assays are run off the same blood sample, drawn at a prevaccination visit.

If the child has evidence of prior dengue, they can proceed with vaccination to protect against recurrent infection. Dengvaxia is given as a series of three shots over 6 months. Vaccine efficacy is 82% – so not everyone is protected, and additionally, that protection declines over time.

There is concern that it will be difficult to achieve compliance with such a complex regimen. Dr. Paz-Bailey said, “But I think that the trust in vaccines that is highly prevalent for [Puerto] Rico and trusting the health care system, and sort of the importance that is assigned to dengue by providers and by parents because of previous outbreaks and previous experiences is going to help us.” She added, “I think that the COVID experience has been very revealing. And what we have learned is that Puerto Rico has a very strong health care system, a very strong network of vaccine providers. ... Coverage for COVID vaccine is higher than in other parts of the U.S.”

One of the interesting things about dengue is that the first infection can range from asymptomatic to life-threatening. The second infection is generally worse because of this antibody-dependent enhancement phenomenon. Eng Eong Ooi, MD, PhD, professor of microbiology and immunology, National University of Singapore, told this news organization, “After you have two infections, you seem to be protected quite well against the remaining two [serotypes]. The vaccine serves as another episode of infection in those who had prior dengue, so then any natural infections after the vaccination in the seropositive become like the outcome of a third or fourth infection.”

Vaccination alone will not solve dengue. Dr. Ooi said, “There’s not one method that would fully control dengue. You need both vaccines as well as control measures, whether it’s Wolbachia or something else. At the same time, I think we need antiviral drugs, because hitting this virus in just one part of its life cycle wouldn’t make a huge, lasting impact.” Dr. Ooi added that as “the spread of the virus and the population immunity drops, you’re actually now more vulnerable to dengue outbreaks when they do get introduced. So, suppressing transmission alone isn’t the answer. You also have to keep herd immunity levels high. So if we can reduce the virus transmission by controlling either mosquito population or transmission and at the same time vaccinate to keep the immunity levels high, then I think we have a chance of controlling dengue.”

Dr. Paz-Bailey concluded: “I do want to emphasize that we are excited about having these tools, because for years and years, we have had really limited options to prevent and control dengue. It’s an important addition to have the vaccine be approved to be used within the U.S., and it’s going to pave the road for future vaccines.”

Dr. Paz-Bailey and Dr. Ooi reported no relevant financial relationships.

Quebec, Canada’s second most populous province, announced on Jan. 11 that adult residents who refuse to get vaccinated against COVID-19 will face a financial penalty.

The amount hasn’t been decided yet, but it will be “significant” and more than $100. More details will be released at a later date, The Associated Press reported.

“Those who refuse to get their first doses in the coming weeks will have to pay a new health contribution,” Premier Francois Legault said during a news conference.

Not getting vaccinated burdens the health care system, and not all residents should pay for it, he said. About 10% of adults in Quebec are unvaccinated, but they represent about 50% of intensive care patients.

“I think it’s reasonable a majority of the population is asking that there be consequences,” he said. “It’s a question of fairness for the 90% of the population that have made some sacrifices. We owe them.”

The fine will apply to those who don’t qualify for a medical exemption, Mr. Legault said.

Provinces across Canada have reported a surge in COVID-19 cases due to the Omicron variant, with Quebec being one of the hardest-hit, according to Reuters. The province is regularly recording the highest daily case count across the country.

Quebec also has announced a 10 p.m. to 5 a.m. curfew, the AP reported. Starting Jan. 18, liquor and cannabis stores in the province will require proof of vaccination, and shopping malls and hair salons could soon require them as well.

About a quarter of all Canadians live in Quebec, according to CNN. The province was one of the first in Canada to require proof of vaccination for residents to eat in restaurants, go to the gym, or attend sporting events.

Some European countries have announced fees for unvaccinated residents, the AP reported, but Quebec is the first in Canada to announce a financial penalty for those who don’t get a shot.

In Greece, people older than 60 have until Jan. 16 to receive the first dose, or they will be fined 100 euros for every month they remain unvaccinated, the AP reported.

Austria will impose fines up to 3,600 euros for those who don’t follow the vaccine mandate for ages 14 and older, which is slated to start in February.

In Italy, residents who are 50 and older are required to be vaccinated. In mid-February, those who are unvaccinated could be fined up to 1,600 euros if they enter their workplaces, the AP reported.

For more than a decade, studies on the dubious value of education in the face of vaccine refusal and hesitancy have been accumulating. But, too often, the research has been ignored by folks who believe that they can teach the “misinformed” into dropping their resistance. Among some circles education ranks right up there with apple pie and motherhood as one of the pillars of Americana. Those wedded to the education mantra may acknowledge that teaching and preaching hasn’t worked well in the past. But, they may claim it’s because we haven’t done enough of it or hit the right buttons. The notion that if we can just share the facts with the uninformed everything will be fine is a myth that obviously is going to die slowly.

In a recent op-ed piece in the New York Times two physicians at Harvard Medical School reported on their study of about three-quarters of a million children who were eligible to receive HPV vaccines (2021 Dec 21. “Facts alone aren’t going to win over the unvaccinated. This might,” Anupam B. Jena and Christopher M. Worsham). The researchers found that children whose mothers had been diagnosed with cervical cancer were no more likely to be immunized than those children whose mothers had not had the disease. Who could be better informed about risks and hazards of contracting HPV than women with cervical cancer? If the facts won’t motivate, where does that leave us?

Those of you born before 1960 may remember or at least have heard about a television show called “Truth or Consequences.” It was a silly farce of a game show which has no bearing on our nation’s crisis of widespread vaccine refusal. However, buried in its title is the answer. If the truth isn’t convincing the resistors, then the obvious choice is consequences.

I hope that you have discovered that same strategy when counseling parents of misbehaving children. Talk is cheap and often ineffective. Explaining the error of his ways to a child who probably already knows what he is doing wrong is a waste of everyone’s time and unpleasant for those within earshot. At some point, sooner better than later, it’s time to say there is going to be a consequence for this misbehavior – going home from the playground, spending a few minutes in time-out, removing a privilege, etc. If consequences are chosen well and instituted with a minimum of idle threats, they work.

And, we are beginning to see it work in the face of pandemic shot refusal. Here in Maine the governor mandated that all health care workers be vaccinated. There was plenty of gnashing of teeth and threats of mass job walk offs. And, there were a few hospital workers who quit, but in the end it worked.

The trick is choosing consequences that have some teeth and make sense. Clearly, some folks who have read about the consequences of not getting vaccinated and may have even lost family members to the disease don’t see those losses as significant consequences for whatever reason. The threat of losing a job is likely to get their attention.

Threats must be carried out even though they may be disruptive in the short term. The good thing about well-crafted mandates is that they can be a win-win for everyone. The vaccine resisters don’t need to admit they were wrong. “Those shots are B.S., but the governor made me do it.” The problem is finding leaders who understand that education has its limits and who have the courage to create and administer the consequences.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

For more than a decade, studies on the dubious value of education in the face of vaccine refusal and hesitancy have been accumulating. But, too often, the research has been ignored by folks who believe that they can teach the “misinformed” into dropping their resistance. Among some circles education ranks right up there with apple pie and motherhood as one of the pillars of Americana. Those wedded to the education mantra may acknowledge that teaching and preaching hasn’t worked well in the past. But, they may claim it’s because we haven’t done enough of it or hit the right buttons. The notion that if we can just share the facts with the uninformed everything will be fine is a myth that obviously is going to die slowly.

In a recent op-ed piece in the New York Times two physicians at Harvard Medical School reported on their study of about three-quarters of a million children who were eligible to receive HPV vaccines (2021 Dec 21. “Facts alone aren’t going to win over the unvaccinated. This might,” Anupam B. Jena and Christopher M. Worsham). The researchers found that children whose mothers had been diagnosed with cervical cancer were no more likely to be immunized than those children whose mothers had not had the disease. Who could be better informed about risks and hazards of contracting HPV than women with cervical cancer? If the facts won’t motivate, where does that leave us?

Those of you born before 1960 may remember or at least have heard about a television show called “Truth or Consequences.” It was a silly farce of a game show which has no bearing on our nation’s crisis of widespread vaccine refusal. However, buried in its title is the answer. If the truth isn’t convincing the resistors, then the obvious choice is consequences.

Hospital admissions of U.S. children younger than 5 – the only group ineligible for vaccination – have reached their peak since the start of the pandemic, according to new data from the Centers for Disease Control and Prevention.

CDC Director Rochelle Walensky, MD, said the higher numbers show the importance of vaccination for all eligible groups.

“This is the highest number of pediatric hospitalizations we’ve seen throughout the pandemic, which we said about Delta until now,” she said at a CDC briefing Friday. “This very well may be that there are just more cases out there, and our children are more vulnerable when they have more cases surrounding them.”

Despite the skyrocketing admissions, hospitalizations are still relatively low for children, she said. The hospitalization rate for children under 5 is 4 in 100,000, and it’s about 1 in 100,000 in children 5-17.

Dr. Walensky said not all children are being hospitalized for COVID-19 – some are admitted for unrelated issues and test positive but don’t have symptoms.

“We are still learning more about the severity of Omicron in children,” she said, noting that just over 50% of children 12-18 are fully vaccinated, while only 16% of those ages 5-11 are fully vaccinated.

Friday’s teleconference was the first CDC briefing in several months and comes on the heels of recent guideline updates for testing and isolation that have left the American public dumbfounded. When asked why the briefing was held, Dr. Walensky said there had been interest in hearing more from the CDC, saying, “I anticipate this will be the first of many briefings.”

She also defended the confusing guideline changes, saying, “We’re in an unprecedented time with the speed of Omicron cases rising. … This is hard, and I am committed to continuing to improve as we learn more about the science and communicate that to you.”

Lack of a high school education is a predictor of whether a person will be resistant to getting the COVID-19 vaccine, a new study shows.

Researchers from the University of North Carolina looked at vaccination rates in 3,142 counties in the U.S. They compared them to population characteristics based on the CDC Social Vulnerability Index.

They found that more than half of the unvaccinated adults in the U.S. with strong vaccine hesitancy had a high school education or less. Vaccine hesitancy was defined as refusal to be vaccinated even if the COVID-19 vaccine was available.

The other main predictor for vaccine hesitancy was concern about vaccine availability and distribution, the researchers said.

“Our study suggests that low education levels are a major contributor to vaccine hesitancy and ultimately vaccination levels,” the authors wrote. The study was published in the American Journal of Infection Control. “Specifically, low vaccination levels were found in communities with a less educated population and with more concern about vaccine uptake capacity, suggesting that education is an ongoing challenge.”

“Our findings suggest that policy makers and community leaders should tailor vaccine information and efforts to those with limited education and specifically address knowledge concerns that are prevalent and likely more modifiable.”

The study was based on data gathered months ago. It says that as of May 9, 2021, 34.7% of the U.S. population was fully vaccinated and that 8% reported a strong unwillingness to get vaccinated.

At press time, the Centers for Disease Control and Prevention’s COVID Data Tracker showed that 62.5% of the U.S. population was fully vaccinated.

According to the study, other consistent characteristics of people who are vaccine hesitant are that they belong to a racial minority, are 65 or older, live in a household with children 18 or younger, or are unemployed.

When asked why they were vaccine hesitant, people gave these reasons: Lack of trust in COVID-19 vaccines (55%), concerns about side effects (48%), and lack of trust in government (46%).

Lack of access to vaccines, often cited in previous studies about resistance to other vaccines, was not cited as a reason for not getting the COVID-19 vaccine.

“COVID-19 vaccine hesitancy is a public health threat,” the researchers concluded. “Since education levels are not easily modifiable, our results suggest that policymakers would be best served by closing knowledge gaps to overcome negative perceptions of the vaccine through tailored interventions.”

The Mayo Clinic fired 700 employees this week who didn’t comply with its COVID-19 vaccine mandate.

The medical center, which is Minnesota’s largest employer, has major campuses in Arizona, Florida, and Minnesota and operates hospitals in Iowa and Wisconsin.

Employees had until Jan. 3 to get vaccinated or receive approval for an exemption. On Jan. 4, the hospital fired those who didn’t meet the requirement, according to Action News Jax, a CBS affiliate in Florida.

The 700 employees make up about 1% of Mayo Clinic’s 73,000-person workforce. So far, none of the employees at the campus in Jacksonville, Fla., have been affected, the news outlet reported.

“Florida staff who are not in compliance with our vaccination program remain employed pending the outcome of litigation related to the Centers for Medicare & Medicaid Services requirements,” a Mayo Clinic spokesperson told Action News Jax.

The federal government and Florida remain at odds over vaccine mandates, and several lawsuits are winding through the court system. Florida Gov. Ron DeSantis signed legislation in November that bans private Florida employers from requiring all employees to get vaccinated and calls for various exemption options, according to The Florida Times-Union. The state law clashes with a federal rule that requires vaccinations for all health care workers at hospitals that receive Medicare and Medicaid funding.

The Mayo Clinic mandate required employees to receive at least one COVID-19 vaccine dose and not be “overdue” for a second dose, according to the statement. Only medical and religious exemptions were allowed, and most medical and religious exemptions were approved.

“While Mayo Clinic is saddened to lose valuable employees, we need to take all steps necessary to keep our patients, workforce, visitors, and communities safe,” Mayo Clinic wrote in its statement. “If individuals released from employment choose to get vaccinated at a later date, the opportunity exists for them to apply and return to Mayo Clinic for future job openings.”

With the latest surge in COVID-19 cases from the Omicron variant, the Mayo Clinic also encouraged unvaccinated people to get a shot and those who are eligible for a booster to get one “as soon as possible.”

“Based on science and data, it’s clear that vaccination keeps people out of the hospital and saves lives,” according to the statement. “That’s true for everyone in our communities – and it’s especially true for the many patients with serious or complex diseases who seek care at Mayo Clinic each day.”

Women may rest a bit easier thanks to results from a study showing that vaccination against the SARS-CoV-2 virus has almost no impact on a woman’s menstrual cycle. The issue is significant, as regular menstruation is a sign of health and fertility, and fears of disturbances might increase vaccination hesitancy as COVID-19 cases continue to surge.

Alison Edelman, MD, MPH, a professor of obstetrics and gynecology at Oregon Health & Science University, Portland, led a group studying prospective data on almost 24,000 menstrual cycles reported by almost 4,000 U.S. women.

The investigators found that COVID-19 vaccination was associated with a less than 1-day change in cycle length for the menstrual cycles after the first and second inoculations, compared with prevaccine cycles. Vaccination had no effect on the actual number of days menstrual bleeding lasted.

The study looked at the menstrual patterns of women aged 18-45 years with normal cycle lengths of 24-38 days for the three consecutive cycles before the first vaccine dose and for three consecutive postvaccine cycles. The final sample included 2,403 vaccinated and 1,556 unvaccinated individuals.

In vaccinated women, the study initially found a slight average increase in cycle length after dose one of 71% of a day and 91% of a day after dose two. Following adjustments, those increases dropped to 64% of a day after the first dose and 79% of a day after the second dose.

In unvaccinated women, the study looked at six cycles over a similar time period and found no significant changes from baseline.

“Coronavirus disease 2019 vaccination is associated with a small change in cycle length but not menses length,” Dr. Edelman’s group concluded in Obstetrics and Gynecology.

In the rare instance that a woman received two vaccine doses within the same menstrual cycle, the change in length could increase to 2 days. These variations appear to resolve quickly, possibly as soon as the next cycle after vaccination and do not indicate any cause for long-term physical or reproductive health concern, according to the authors.

Reports by women on social media, however, have suggested that postvaccine menstrual disruptions are more common with, for example, heavier and breakthrough bleeding. But it appears such changes are temporary and resolve quickly.

“These findings are reassuring and validating,” Dr. Edelman said in an interview. On a population level, the changes indicate no cause for concern for long-term physical or reproductive health and no reason to avoid vaccination. “On a personal level, people want this information so they know what to expect when they get vaccinated, and not worry about a pregnancy scare or be disappointed if they were trying for pregnancy.”

Feinstein Institutes for Medical Research

According to the International Federation of Gynecologists and Obstetricians, variations in cycle length of fewer than 8 days are considered normal, said Christine Metz, PhD, a research biologist and a professor of molecular medicine at the Feinstein Institutes for Medical Research in Manhasset, N.Y. “Thus, the extra 17 hours added to the menstrual cycle length in the vaccination group in this study is well within the ‘normal’ range.”

In a group of about 1,600 menstruating women being studied at Dr. Metz’s center, some have anecdotally reported transient cycle changes post vaccination for COVID-19, including delays in menstruation onset and changes in bleeding patterns.

Exactly how vaccination might alter menstrual cycle length is not known and has not been studied with vaccination against other infections such as influenza and meningococcal disease.

“Many factors are known to affect menstrual cycle length including changes in diet, sleep, and exercise, as well as sickness, travel, and stress,” Dr. Metz said. The COVID-19 vaccines have affected people in different ways, with side effects ranging from injection-site pain to nausea, aches, fever, and fatigue. “Vaccination side effects, particularly if severe, could lead to changes in diet, exercise, and sleep, and feelings of sickness and/or stress.”

These stressors can alter hormone production and stability, as well as the body’s response to hormones such as estrogen, progesterone, follicle-stimulating hormone, luteinizing hormone, and other hormones associated with female reproduction. “Because these hormones regulate the menstrual cycle, variations in these hormones can either shorten or lengthen the cycle,” Dr. Metz explained.

More research needs to be done at the global level, according to the authors. “Questions remain about other possible changes in menstrual cycles, such as menstrual symptoms, unscheduled bleeding, and changes in the quality and quantity of menstrual bleeding.”

This research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development and the National Institutes of Health’s Office of Research on Women’s Health. Dr. Edelman reported support from the American College of Obstetrics and Gynecology, the World Health Organization, Gynuity, and the Karolinska Institute as well as royalties from UpToDate. Other study authors reported similar relationships with not-for-profit and private-sector companies. Three coauthors are employees of Natural Cycles, a fertility tracking device that was used in the study. Dr. Metz disclosed no conflicts of interest with regard to her comments.

In unvaccinated women, the study looked at six cycles over a similar time period and found no significant changes from baseline.

“Coronavirus disease 2019 vaccination is associated with a small change in cycle length but not menses length,” Dr. Edelman’s group concluded in Obstetrics and Gynecology.

In the rare instance that a woman received two vaccine doses within the same menstrual cycle, the change in length could increase to 2 days. These variations appear to resolve quickly, possibly as soon as the next cycle after vaccination and do not indicate any cause for long-term physical or reproductive health concern, according to the authors.

Reports by women on social media, however, have suggested that postvaccine menstrual disruptions are more common with, for example, heavier and breakthrough bleeding. But it appears such changes are temporary and resolve quickly.

“These findings are reassuring and validating,” Dr. Edelman said in an interview. On a population level, the changes indicate no cause for concern for long-term physical or reproductive health and no reason to avoid vaccination. “On a personal level, people want this information so they know what to expect when they get vaccinated, and not worry about a pregnancy scare or be disappointed if they were trying for pregnancy.”

Feinstein Institutes for Medical Research

According to the International Federation of Gynecologists and Obstetricians, variations in cycle length of fewer than 8 days are considered normal, said Christine Metz, PhD, a research biologist and a professor of molecular medicine at the Feinstein Institutes for Medical Research in Manhasset, N.Y. “Thus, the extra 17 hours added to the menstrual cycle length in the vaccination group in this study is well within the ‘normal’ range.”

In a group of about 1,600 menstruating women being studied at Dr. Metz’s center, some have anecdotally reported transient cycle changes post vaccination for COVID-19, including delays in menstruation onset and changes in bleeding patterns.

Exactly how vaccination might alter menstrual cycle length is not known and has not been studied with vaccination against other infections such as influenza and meningococcal disease.

“Many factors are known to affect menstrual cycle length including changes in diet, sleep, and exercise, as well as sickness, travel, and stress,” Dr. Metz said. The COVID-19 vaccines have affected people in different ways, with side effects ranging from injection-site pain to nausea, aches, fever, and fatigue. “Vaccination side effects, particularly if severe, could lead to changes in diet, exercise, and sleep, and feelings of sickness and/or stress.”

These stressors can alter hormone production and stability, as well as the body’s response to hormones such as estrogen, progesterone, follicle-stimulating hormone, luteinizing hormone, and other hormones associated with female reproduction. “Because these hormones regulate the menstrual cycle, variations in these hormones can either shorten or lengthen the cycle,” Dr. Metz explained.

More research needs to be done at the global level, according to the authors. “Questions remain about other possible changes in menstrual cycles, such as menstrual symptoms, unscheduled bleeding, and changes in the quality and quantity of menstrual bleeding.”

This research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development and the National Institutes of Health’s Office of Research on Women’s Health. Dr. Edelman reported support from the American College of Obstetrics and Gynecology, the World Health Organization, Gynuity, and the Karolinska Institute as well as royalties from UpToDate. Other study authors reported similar relationships with not-for-profit and private-sector companies. Three coauthors are employees of Natural Cycles, a fertility tracking device that was used in the study. Dr. Metz disclosed no conflicts of interest with regard to her comments.
 

Women may rest a bit easier thanks to results from a study showing that vaccination against the SARS-CoV-2 virus has almost no impact on a woman’s menstrual cycle. The issue is significant, as regular menstruation is a sign of health and fertility, and fears of disturbances might increase vaccination hesitancy as COVID-19 cases continue to surge.

Alison Edelman, MD, MPH, a professor of obstetrics and gynecology at Oregon Health & Science University, Portland, led a group studying prospective data on almost 24,000 menstrual cycles reported by almost 4,000 U.S. women.

The investigators found that COVID-19 vaccination was associated with a less than 1-day change in cycle length for the menstrual cycles after the first and second inoculations, compared with prevaccine cycles. Vaccination had no effect on the actual number of days menstrual bleeding lasted.

The study looked at the menstrual patterns of women aged 18-45 years with normal cycle lengths of 24-38 days for the three consecutive cycles before the first vaccine dose and for three consecutive postvaccine cycles. The final sample included 2,403 vaccinated and 1,556 unvaccinated individuals.

In vaccinated women, the study initially found a slight average increase in cycle length after dose one of 71% of a day and 91% of a day after dose two. Following adjustments, those increases dropped to 64% of a day after the first dose and 79% of a day after the second dose.

A CDC advisory panel recommended on Jan. 5 that 12- to 17-year-olds in the U.S. should get the Pfizer COVID-19 booster shot 5 months after a primary series of vaccinations.

The CDC had already said 16- and 17-year-olds “may” receive a Pfizer booster but the new recommendation adds the 12- to 15-year-old group and strengthens the “may” to “should” for 16- and 17-year-olds.

The committee voted 13-1 to recommend the booster for ages 12-17. CDC Director Rochelle Walensky, MD, must still approve the recommendation for it to take effect.

The vote comes after the FDA on Jan. 3 authorized the Pfizer vaccine booster dose for 12- to 15-year-olds.

The FDA action updated the authorization for the Pfizer vaccine, and the agency also shortened the recommended time between a second dose and the booster to 5 months or more (from 6 months). A third primary series dose is also now authorized for certain immunocompromised children between 5 and 11 years old. Full details are available in an FDA news release.

The CDC on Jan. 4 also backed the shortened time frame and a third primary series dose for some immunocompromised children 5-11 years old. But the CDC delayed a decision on a booster for 12- to 15-year-olds until it heard from its Advisory Committee on Immunization Practices on Jan. 5.

The decision came as school districts nationwide are wrestling with decisions of whether to keep schools open or revert to a virtual format as cases surge, and as pediatric COVID-19 cases and hospitalizations reach new highs.

The only dissenting vote came from Helen Keipp Talbot, MD, associate professor of medicine at Vanderbilt University in Nashville, Tenn.

She said after the vote, “I am just fine with kids getting a booster. This is not me against all boosters. I just really want the U.S. to move forward with all kids.”

Dr. Talbot said earlier in the comment period, “If we divert our public health from the unvaccinated to the vaccinated, we are not going to make a big impact. Boosters are incredibly important but they won’t solve this problem of the crowded hospitals.”

She said vaccinating the unvaccinated must be the priority.

“If you are a parent out there who has not yet vaccinated your child because you have questions, please, please talk to a health care provider,” she said.

Among the 13 supporters of the recommendation was Oliver Brooks, MD, chief medical officer of Watts HealthCare Corporation in Los Angeles.

Dr. Brooks said extending the population for boosters is another tool in the toolbox.

“If it’s a hammer, we should hit that nail hard,” he said.

Sara Oliver, MD, ACIP’s lead for the COVID-19 work group, presented the case behind the recommendation.

She noted the soaring Omicron cases.

“As of Jan. 3, the 7-day average had reached an all-time high of nearly 500,000 cases,” Dr. Oliver noted.

Since this summer, she said, adolescents have had a higher rate of incidence than that of adults.

“The majority of COVID cases continue to occur among the unvaccinated,” she said, “with unvaccinated 12- to 17-year-olds having a 7-times-higher risk of testing positive for SARS-CoV-2 compared to vaccinated 12- to 17-year-olds. Unvaccinated 12- to 17-year-olds have around 11 times higher risk of hospitalization than vaccinated 12- to 17-year-olds.

“Vaccine effectiveness in adolescents 12-15 years old remains high,” Dr. Oliver said, but evidence shows there may be “some waning over time.”

Discussion of risk centered on myocarditis.

Dr. Oliver said myocarditis rates reported after the Pfizer vaccine in Israel across all populations as of Dec. 15 show that “the rates of myocarditis after a third dose are lower than what is seen after the second dose.”

The CDC has released two studies that showed vaccine safety for ages 5-11 and emphasized the importance of vaccinating children against the coronavirus to prevent serious illness and hospitalization.

In one study published in the Morbidity and Mortality Weekly Report, researchers found that serious problems were rare among children who had received the Pfizer vaccine.

In another study, researchers looked at hundreds of pediatric hospitalizations from the summer and found that nearly all of children who developed severe COVID-19 weren’t fully vaccinated.

“This study demonstrates that unvaccinated children hospitalized for COVID-19 could experience severe disease and reinforces the importance of vaccination of all eligible children to provide individual protection and to protect those who are not yet eligible to be vaccinated,” the authors of the second study wrote.

Nearly 9 million doses of the Pfizer vaccine have been given to children aged 5-11 in the United States so far, according to The New York Times. By mid-December, or about 6 weeks after the age group became eligible for vaccination in October, the CDC said it had received very few reports of serious problems.

CDC researchers evaluated reports received from doctors and the public, including survey responses from parents and guardians of about 43,000 children between ages 5 and 11. Many children reported nonserious events such as pain at the injection site, fatigue, or a headache, especially after the second dose.

Among more than 4,100 adverse event reports received in November and December, 100 were for serious events, with the most common being fever or vomiting.

The CDC had received 11 verified reports of myocarditis, or inflammation of the heart muscle, which has been noted as a rare side effect of the vaccine among boys and men between ages 12 and 29. Among those, seven children had already recovered and four were still recovering at the time of the report.

The CDC received reports of two deaths – girls who were aged 5 and 6 – who had chronic medical conditions and were in “fragile health” before their shots. The agency said that no data suggested a “causal association between death and vaccination.”

The CDC also received some reports that children between ages 5 and 11 received the larger vaccine dose meant for older children and adults. Most reports said that the children didn’t experience any problems after an incorrect dose.

In a separate study about pediatric hospitalizations, CDC researchers looked at more than 700 children under age 18 who were hospitalized for COVID-19 in July and August at six children’s hospitals in Arkansas, Florida, Illinois, Louisiana, Texas, and Washington, D.C.

Researchers found that only one of the 272 vaccine-eligible patients between ages 12 and 17 had been fully vaccinated, and 12 were partially vaccinated.

In addition, about two-thirds of the hospitalized children between ages 12 and 17 had an underlying condition, with obesity being the most common. About one-third of children under age 5 had more than one viral infection.

Overall, about 30% of the children had to be treated in intensive care units, and 15% needed invasive medical ventilation, CDC researchers found. Nearly 3% had multisystem inflammatory syndrome in children, or MIS-C, which is a rare but serious inflammatory condition associated with COVID-19.

Among all the children hospitalized with COVID-19, about 1.5% died.

“Few vaccine-eligible patients hospitalized for COVID-19 were vaccinated, highlighting the importance of vaccination for those aged ≥5 years and other prevention strategies to protect children and adolescents from COVID-19, particularly those with underlying medical conditions,” study authors wrote.
