Trump and Bobby Jr. continue relentless attack on life-saving vaccines.

Trump signs executive order to break up measles, mumps, rubella vaccine

Donald Trump is calling to "break up" the measles, mumps, and rubella (MMR) vaccine, which would require more visits and shots, instead of using a two-dose regimen to deliver the three immunizations. 

Separating out the MMR vaccine is among the recommendations in an executive order signed by the president today that urges all childhood vaccines be administered at separate visits.

“For example, at one year, you should have five separate visits for vaccines rather than getting them all in the same day," President Trump said at the signing.

There are no data to show that spacing out the MMR immunizations—or other childhood immunizations—is beneficial, but doing so could increase the risk of infection or lead to kids missing doses. And it adds to vaccination costs.

Also, breaking up the MMR vaccine could be difficult, at least in the short term, as this would require buy-in from pharmaceutical manufacturers to make three separate vaccines. And the proposed three separate vaccines are not currently licensed in the United States nor approved by the Food and Drug Administration, which would take some time.

‘None of this is reality-based’

The executive order makes no mention of autism. Yet, at today's signing, Trump and Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. repeated a long-debunked falsehood that vaccinations are possibly associated with the neurodevelopmental condition. There is no link.

The executive order will do nothing to support families of children with autism or advance understanding of it, said a statement from Andrew D. Racine, MD, PhD, president of the American Academy of Pediatrics (AAP).*

Racine added that pediatricians recommend that children receive certain vaccines at specific ages based on when children's immune systems will respond best and when they are most vulnerable to certain diseases. 

"Nobody has studied?" That's a bald-faced lie
"Delaying or skipping shots is risky, especially as measles continues to spread and children go back to school," he said.

The president also said that the United States recommends more immunizations than peer nations. This is confusing at best. As Stat News explained earlier this year, many other wealthy countries, including the United Kingdom, Israel, and Australia, recommend kids receive more immunizations than the United States would if an HHS immunization recommendation in January were to go into effect. 

“None of this is reality-based,” said Amesh Adlaja, MD, a senior scholar at the Johns Hopkins Center for Health Security, on Bluesky. “It is all just nihilistic pandering to the anti-vaccine movement and will do nothing but lower standards of living for everyone.”

Medical experts warn of harm to kids

To date, at least 23 states have said they plan to follow vaccine recommendations from AAP, which continues to recommend immunization policies that predate the Trump administration. The order advises states and territories to consider updating their vaccine laws and regulations, and it directs the attorney general to take legal action against states with laws that violate religious freedom, disability accommodations, or parental authority. 

The president's directive is designed to restore parental autonomy and repair the relationship between parents and public health, said Jay Bhattacharya, MD, PhD, director of the National Institutes of Health.

But public health experts worry that the order will create more confusion for parents.

"Parents deserve clear, evidence-based guidance about how to protect their children, not competing recommendations issued through political processes," said Michael Osterholm, PhD, MPH, head of the Vaccine Integrity Project and director of the University of Minnesota's Center for Infectious Disease Research and Policy, which publishes CIDRAP News. 

Osterholm said the executive order does not change the underlying decades of scientific evidence on the safety and real-world effectiveness of childhood immunization, and that confidence in vaccination suffers when families receive conflicting messages, and children ultimately bear the consequences.

Parents deserve clear, evidence-based guidance about how to protect their children, not competing recommendations issued through political processes.

Jan K. Carney, MD, MPH, the president of the American College of Physicians, agrees that the administration's dismissal of proven science is troubling, and warned that the executive order could increase medical costs for patients and families, including additional copays, due to needing to schedule multiple appointments.

“Children and caregivers deserve better consideration for the downstream impact of these proposed changes,” he said in a statement.

Order does not trump states' legal authority 

The executive order comes as the president grapples with a historically low approval rating ahead of the midterm elections.

At the same time, public trust in vaccines has dropped, and an important part of the coalition that led to Trump's second term is Kennedy's Make America Healthy Again movement, which includes voters who are skeptical of vaccines and resistant to government influence.

Still, it is the Centers for Disease Control and Prevention, not the president, that sets federal vaccine recommendations, said Dorit Reiss, PhD, who specializes in vaccine law at the University of California College of the Law, San Francisco. 

But, Reiss noted, the executive order could create political pressure on states to make changes to vaccine policy.

Under the order, vaccines for 11 diseases—including measles, polio, and whooping cough— would be recommended for all children. Other vaccines, like those for meningococcal disease and hepatitis B, are recommended only for high-risk children, while flu and COVID vaccination should be based on discussions between doctors and parents. 

That part of the order is similar to the new childhood vaccine schedule announced by HHS on January 5. Those changes, which were based on an HHS scientific assessment, were blocked by a federal judge on March 16.
