Trump signs order to limit childhood vaccines and split MMR shots

August 11, 2026

President Donald Trump has signed an executive order recommending a reduction in childhood vaccines from 18 to 11 shots and suggesting that the combined MMR vaccine be split into separate doses for measles, mumps, and rubella. Trump cited discredited claims linking vaccines to autism and suggested the MMR vaccine could be "lethal" when given as a single dose, despite scientific evidence showing no such dangers. The order functions as guidance rather than a mandate, as vaccination requirements for school attendance are determined by individual states.

Who is affected

Children in the United States who receive childhood vaccinations
Parents who make vaccination decisions for their children
Healthcare providers and doctors who administer vaccines
State-level education systems that set school attendance vaccine requirements
The American Academy of Pediatrics (AAP)
Secretary of Health and Human Services Robert F. Kennedy Jr.
The Centers for Disease Control and Prevention (CDC)
Republican Senator Bill Cassidy

What action is being taken

President Trump has signed an executive order calling for fewer childhood vaccines
The order recommends reducing childhood vaccines from 18 to 11
The order recommends splitting the MMR vaccine into separate shots
Secretary of Health and Human Services Robert F. Kennedy Jr. is seeking to change and loosen vaccine regulations

Why it matters

This executive order matters because it could significantly reduce childhood vaccination rates based on scientifically discredited claims linking vaccines to autism, potentially exposing children to preventable and dangerous diseases like measles. Medical experts warn that delaying or skipping vaccinations poses serious health risks, particularly as measles continues to spread. While the order serves as guidance rather than a federal mandate, it could influence parental decisions and undermine public health efforts that have successfully controlled previously common childhood diseases through widespread vaccination programs.
