- President Donald Trump on Monday signed an executive order calling for fewer routine vaccines for kids, saying he wants to whittle down the number of recommended childhood shots to 11.
- The order overrides CDC vaccine schedule and breaks up the measles, mumps, and rubella (MMR) vaccine into three separate shots.
- Trump falsely tied vaccines to autism, suggesting that rising rates of childhood shots have led to an increase in autism diagnoses.
- The order directs the Department of Justice to investigate states in violation of exemptions for childhood vaccine mandates.
- Health experts warn that splitting the MMR shot raises the chance of missed appointments and skipped immunizations.
- The executive order is part of the Trump administration's efforts to reshape the childhood shot schedule under Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic.
- Decades of scientific evidence has shown no link between autism and childhood vaccines.
- Trump's executive order comes as the U.S. logs its lowest vaccination rates in decades, with rates having fallen since the Covid-19 pandemic.
- The order states that, to the maximum extent feasible, all childhood immunizations should be administered at separate medical visits.
- Trump has repeatedly linked vaccines to autism, despite dozens of studies showing no link.
President Donald Trump's recent executive order aims to significantly alter the childhood vaccination schedule, reducing the number of recommended vaccines to 11 and mandating that the MMR vaccine be administered as three separate shots.
“The MMR we want to have separate visits, separate times,” Trump stated, emphasizing the need for individual doses despite the lack of scientific backing for his claims.
The order also directs the Department of Justice to investigate state compliance with vaccine mandates, potentially challenging laws that allow exemptions.
Critics warn that this approach could lead to increased missed appointments and skipped immunizations, as it requires more doctor visits.
“This would put a financial and logistical strain on families and medical providers,” experts caution.

Trump has repeatedly linked vaccines to autism, despite overwhelming evidence refuting this connection.12
“Decades of scientific evidence has shown no link between autism and childhood vaccines,” health experts assert.9
The executive order, while significant, is not legally binding and serves primarily as guidance for federal agencies.
“This should have no direct operational effects,” noted Dorit Reiss, a vaccines expert at UC Law San Francisco.
The implications of this order could reshape vaccination practices across the nation, as many states have already decoupled their requirements from CDC recommendations.
“The order directs the Justice Department to investigate state vaccine mandate exemptions, and it pushes six shots—including flu and Covid-19—into shared clinical decision-making. Experts warn that splitting MMR into separate visits raises missed-appointment risks, and the order has no direct legal effect on the public.”
