Trump signs executive order to reduce childhood vaccines

President Donald Trump signed an executive order on August 10, 2026, that aims to reduce the number of recommended childhood vaccines from 17 to 11 and to separate the combined measles, mumps, and rubella (MMR) vaccine into three individual shots administered at separate visits Source: AP News, CNN. The order also directs the Department of Justice to investigate state vaccine mandates for potential violations of parental and religious rights Source: CNBC.

What the order does

The order creates three vaccine categories: those recommended for all children, those for high-risk groups, and those subject to shared clinical decision-making. It removes hepatitis B, rotavirus, influenza, and RSV from the universal recommendation Source: DW. It also calls for splitting the MMR vaccine, a move that public health experts warn could increase the risk of missed doses and disease outbreaks Source: Euronews.

The reaction

Medical groups and public health officials have strongly criticized the order. The American Academy of Pediatrics called it "wrong" and said it spreads "uncertainty, fear, and confusion" Source: Euronews. WHO Director-General Tedros Adhanom Ghebreyesus stated that the science is "unequivocal: vaccines – including the MMR vaccine – are safe and do not cause autism" Source: SCMP. However, some "Make America Healthy Again" voters see the order as a win, and Trump's spokesperson said it would give parents more options Source: AP News.

What's next

The order does not immediately change vaccine availability or school requirements, as states control mandates Source: NPR. Legal challenges are likely, as a federal judge previously blocked similar HHS changes Source: Gizmodo. The order may also become a political issue in the upcoming midterm elections, with Democrats planning to use it to attack Republican candidates Source: AP News.
