President Donald Trump’s plan to overhaul childhood vaccinations in the United States could face major financial and logistical hurdles, even as public health experts question the scientific basis for the changes.
An executive order signed by Trump on Monday calls for combination vaccines to be separated into individual shots, including the measles, mumps and rubella (MMR) vaccine. It also directs officials to encourage greater spacing between vaccinations wherever possible, as per an Associated Press report.
