Trump signs order to overhaul childhood vaccine schedule

President Donald Trump signed an executive order on Monday seeking to overhaul the US childhood vaccination schedule, recommending that the measles, mumps and rubella (MMR) vaccine be split into three separate shots given at different visits. The order also reduces the number of vaccines recommended for all children from 17 to 11, while five others would be limited to high-risk groups. The move attempts to override CDC authority and has been halted by a federal judge.
