(The Hill) — The decision by Secretary of Health and Human Services Robert F. Kennedy Jr. to dismiss the entire vaccine board at the Centers for Disease Control and Prevention (CDC) is causing significant concern, especially as childhood vaccination rates continue to decline. This move is particularly troubling as the next school year approaches. 

Health officials are apprehensive about the implications of Kennedy’s recent actions and his general stance on vaccines, as schools gear up for their first year with him leading the nation’s health efforts.  

Diseases that had been previously eradicated in the U.S. are making a comeback, and experts emphasize the importance of schools remaining vigilant and preparing for potential outbreaks among their students. 

So far this year, there have been nearly 1,200 cases of measles reported in 34 states, quadruple the total from all of last year. And the CDC says vaccine coverage among kindergarteners for measles, mumps and rubella (MMR) is below the target 95 percent threshold. 

“I think schools are going to have to rely on state-level and national experts to help guide their policies. This means that the current CDC recommendations for school-based vaccinations are still the most reliable and evidence-based,” said Lawrence Gostin, distinguished professor of global health law at Georgetown University. 

“If the secretary changes the childhood vaccination schedule, and I think he is all but certain to do that soon, states should hold fast on the current recommendations and consult their own health departments for future guidance,” Gostin added. 

Kennedy replaced the 17-member Advisory Committee on Immunization Practices (ACIP) with eight new voting members, some of whom are known for spreading vaccine misinformation. Robert W. Malone, one of the new members, also promoted the use of hydroxychloroquine and ivermectin during the COVID-19 pandemic.

“A clean sweep is needed to re-establish public confidence in vaccine science,” Kennedy wrote.  

“The public must know that unbiased science—evaluated through a transparent process and insulated from conflicts of interest—guides the recommendations of our health agencies,” he added in a subsequent statement. 

After the initial measles outbreak in Texas, Kennedy made multiple appearances on Fox News where he downplayed the severity of the disease and gave questionable advice on treatments, including emphasizing the use of vitamin A.

The Health Secretary at first suggested natural immunity gained from having measles is more useful than the vaccine, though he later conceded the MMR shot is the “most effective way” to prevent the disease.

“The changes at ACIP … were not unexpected, but they are jarring,” said Josh Michaud, senior expert in U.S. and global vaccine policy for KFF, a health policy research and news organization. 

Michaud fears that the firings and RFK Jr.’s vaccine skepticism will have a negative “effect on parents who might have been on the fence about vaccinations or allow more space for policy-makers at the state and local level to change the rules about vaccinations.” 

Schools only have a few months to prepare, as a reversal in vaccination trends is unlikely to occur in the near future.

Research published this month by Johns Hopkins University in JAMA showed 1,600 counties around the country have vaccination rates below 91 percent, missing the 95 percent mark for herd immunity.  

The only states that have seen an increase in county-level immunizations are California, Massachusetts, Connecticut and New York.  

“I believe that most, if not all, blue states will continue to have rigorous science-based rules for vaccinating children as a condition of school entry. But many red states will follow RFK. Jr.’s advice,” Gostin said. 

“In those states, parents should make sure that their children and family members are all up to date on currently recommended vaccinations. I don’t think they should be reluctant to send their children to school or to have them wear masks. That is overkill,” he added. “If they are fully vaccinated, children will be protected. If the child is immunocompromised, then extra precautions may be needed.” 

Schools will also need to review their policies on how to deal with outbreaks and potentially look at past advice — and not future federal guidance — for how to handle vaccine recommendations. 

“I think it’s really for schools as they are thinking about their policies, and the policies that many of these school districts have had for many, many years, in terms of the vaccination schedules, in terms of requirements around vaccinations — to really think about the importance of vaccinations for children and to follow the policies that have worked for many years,” said Neil Maniar, professor of public health practice at Northeastern University.  

Along with the rise in measles and growing “risk for other infectious diseases,” schools may also have to contend with “higher rates of the flu and RSV and other communicable diseases” than in years past, Maniar said.

“So we really want to make sure that schools are putting forth policies that are designed to really promote the health and well-being of children and their families and others in the community,” he added.
