President Trump signs executive order to reduce childhood vaccines and split MMR doses, sparking debate over public health and federal authority.

President Trump signed an order to cut the number of childhood vaccines to 11 core shots and split the MMR vaccines into separate visits. He cited past vaccination schedules as safer and linked high autism rates to modern vaccines. The order does not carry legal force, as school vaccine mandates are set by state governments. While the public health community disputes the link between MMR and autism, the move is expected to stir controversy and potentially prompt legal challenges.

President Donald Trump has signed an executive order that calls for reducing the number of childhood vaccines and recommends splitting the mumps, measles and rubella (MMR) shots into separate visits.

During a televised briefing on Monday, Trump justified the move by claiming that past vaccination schedules were far less intensive, and that the current high rates of autism were therefore an opportunistic outcome of modern vaccination practices.

While the United States currently has no federal mandate for a specific vaccine schedule—school attendance requirements are set at the state level—state health departments will not be able to implement these new recommendations without local legislation.

The order lists 11 core vaccines that the administration claims are essential for preventing serious diseases. They include measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type B, pneumococcal disease, human papillomavirus, and varicella.

Laboratory studies and systematic reviews, however, have found no evidence linking the MMR vaccine to autism. Health experts warn that the order may erode public confidence in immunization programs and could lead to increased outbreaks of preventable illnesses.

Experts note that the administration has a long history of promoting vaccine skepticism, yet federal agencies such as the U.S. Centers for Disease Control and Prevention remain neutral on the new proposal, citing insufficient scientific backing.

The policy will trigger a wave of public debate and possibly legal challenges as states weigh the potential health risks of changing established immunization practices.
