President Donald Trump has signed an executive order aiming to reduce the number of recommended childhood vaccinations in the United States. Currently, the American Academy of Pediatrics advises eighteen vaccinations for children; Trump seeks to lower this to eleven. The order also calls for separating the combined MMR vaccine—protecting against measles, mumps, and rubella—into individual shots. This move raises concerns among medical professionals who emphasize the safety and effectiveness of the current vaccination schedule. The Trump administration argues the need to balance vaccine safety with potential side effects, and to grant parents more control over healthcare decisions. Critics fear this policy could lead to a resurgence of preventable diseases. The long-term effects of this executive order remain to be seen.
