Trump and Vaccine Myths: What Experts Say
On Monday, President Donald Trump issued an executive order recommending states revise childhood vaccine guidelines. This order claims to separate the measles, mumps, and rubella (MMR) vaccine into three single-disease shots. Additionally, it advises spreading childhood vaccines over multiple appointments.
Public health experts worry that delaying vaccines might raise the risk of children contracting diseases before the next medical visit. Vaccine schedules developed worldwide have consistently demonstrated safety and effectiveness in protecting children.
Claims and Facts
TRUMP: “In many cases, we were requiring 72 jabs for our beautiful, healthy, lovely, delicate little children.”
The Facts: This is misleading. In 2025, the federal schedule recommended protection against 18 diseases. The number of injections varied due to factors like brand choice and available combination vaccines. Excluding annual flu vaccines and COVID-19 shots, the figure was closer to three dozen. States mandate certain vaccines for school entrance, but opt-outs are available.
In January, the Trump administration reduced the schedule to 11 diseases. Additional vaccines are categorized for at-risk children or through doctor consultations, lowering injections to about 23 for recommended-for-all vaccines.
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 current combination MMR vaccine proves safe and effective. Side effects are generally mild, involving a sore arm, fever, mild rash, and temporary joint pain. Separate measles, mumps, and rubella vaccines are unavailable in the U.S.
Dr. Aaron Milstone from Johns Hopkins expressed concern that splitting vaccines may lead to under-vaccination due to fears without evidence. Vaccines have a strong safety record supported by extensive data.
TRUMP: “Large amounts of vaccine, large amounts of like vats of vaccine are currently pumped into your child’s body.”
The Facts: This is incorrect. Dr. Molly O’Shea, a Michigan pediatrician, noted vaccine quantities are small, ranging from 0.1 to 0.3 milliliters per dose. A typical soda bottle is about 2,500 times larger than a 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: Experts caution that postponing vaccines as suggested could risk children contracting preventable diseases. Dr. Willie Underwood of the American Medical Association stated vaccines are vital tools. Modifying a tested schedule risks public trust and child health.
Dr. Andrew Racine from the American Academy of Pediatrics pointed out that delaying shots is risky, especially with increasing measles cases as vaccination rates fall. Measles was declared eliminated in 2000, yet recent years show resurgence.
Claims Linking Vaccines and Autism
HEALTH SECRETARY ROBERT F. KENNEDY JR.: “In 1970, the biggest epidemiological study … looked at 900,000 children … and they came back with an incidental rate of .8 per 10,000. … The rate according to CDC today … is one in every 31 children.”
The Facts: Autism diagnoses were rare in the past, given only for severe cases. The term now includes a spectrum of conditions, broadening the diagnosis range. In April 2025, the CDC noted a diagnostic rate of 1 in 31 children.
Trump and Kennedy suggested vaccines might cause autism, but extensive studies show no link. A fraudulent study once claimed a connection with MMR but was retracted.
Dr. Alycia Halladay from the Autism Science Foundation emphasized no environmental factor, including vaccines, has been better studied for links to autism. All research confirms no connection globally.
Kennedy has vowed to pursue research into environmental causes for autism. He promised findings will be shared when ready.
