Trump orders MMR vaccine to be administered as three separate shots, citing autism concerns

President Donald Trump announced via an executive order that the combined measles, mumps and rubella (MMR) vaccine should be split into three individual injections for children.

He claimed the change is necessary because he believes the combined vaccine may be linked to autism, a position that is not supported by scientific research.

The move shifts control of the childhood vaccine schedule to the White House and has prompted public‑health officials to warn about possible effects on vaccination rates and disease prevention.
