Examining Claims on Vaccine Policies and Autism

President Donald Trump issued an executive order on Monday targeting state childhood vaccine recommendations. He and others in his administration repeated inaccurate claims about vaccines and their link to autism. The order suggests splitting the measles, mumps, and rubella (MMR) vaccine into separate shots and spacing childhood vaccines apart. Public health experts worry this could raise the risk of children contracting vaccine-preventable illnesses before their next visit. Scientific research over decades shows that childhood vaccines are safe and effective.

Claims and Facts

TRUMP: “In many cases, we were requiring 72 jabs for our beautiful, healthy, lovely, delicate little children.”

The Facts: This statement is misleading. By 2025, routine protection against 18 diseases was recommended. The total number of injections varied based on factors like vaccine brand and child’s age. Without yearly flu shots or COVID-19 vaccines, the number is closer to three dozen. Vaccines protect against severe, preventable diseases, but they were not mandated; families could opt out. School vaccine requirements differ state by state, with exemptions available. The Trump administration later reduced vaccine recommendations to 11 diseases, decreasing the number of required injections.

TRUMP: “You have the MMR, we want it in three separate vaccinations given at separate times. Together there could be a possibility they are quite lethal and separately, it looks like they are not at all lethal but just very effective.”

The Facts: This claim is false. The MMR vaccine is proven safe and effective. It prevents illness with minor side effects such as a sore arm or mild fever. Separate vaccines for measles, mumps, and rubella aren’t available in the U.S. Dr. Aaron Milstone highlights the extensive scientific data affirming vaccine safety, warning against reducing vaccination out of unfounded fears.

TRUMP: “Large amounts of vaccine, large amounts of like vats of vaccine are currently pumped into your child’s body.”

The Facts: Dr. Molly O’Shea clarifies the small vaccine amounts administered, typically 0.1 to 0.3 milliliters per vaccine, compared to a 5-milliliter teaspoon. Claims of large quantities are incorrect. Trump compared vaccine size to a soda bottle, which is about 500 milliliters, vastly more than a typical vaccine dose.

TRUMP: “There’s nothing that we lose with this. The worst thing that would happen would be nothing happens. We’re not going to lose anything.”

The Facts: Health experts argue that spacing out vaccines, as Trump suggests, heightens the risk of contracting diseases. Dr. Willie Underwood and Dr. Andrew Racine highlight the proven benefits of vaccines and the dangers of postponing them, notably as measles spreads with declining vaccination rates.

Vaccine and Autism Claims

HEALTH SECRETARY ROBERT F. KENNEDY JR.: “In 1970, the biggest epidemiological study at that time in history was performed… [autism incidence rate] less than one in 10,000… rate according to CDC today is one in every 31 children.”

The Facts: Autism diagnoses have increased due to more comprehensive screenings and better recognition, not vaccines. In April 2025, CDC data showed a diagnosis rate of 1 in 31 children. Both Trump and Kennedy suggest a possible link between vaccines and autism, yet studies from the CDC and others have dismissed such claims. The Autism Science Foundation’s Dr. Alycia Halladay reiterates the lack of connection between vaccines and autism, supported by numerous international studies.

Kennedy committed to thorough studies on environmental factors contributing to autism, with results forthcoming.
