President Trump’s directive to divide the MMR vaccine into separate injections could disrupt established childhood immunisation practices in the US, raising fears about increased vulnerability to preventable diseases amid political and scientific controversy.
President Donald Trump has ordered the measles, mumps and rubella vaccine to be broken into three separate injections, a move that would sharply alter long-standing childhood immunisation practice in the United States. According to Axios, the order was signed on August 10 and would require the shots to be given at separate doctor visits, a change public health experts say could make vaccination harder, slower and more expensive.
The Telegraaf reported that Trump cast the change as a return to a “golden standard” that would put the United States in line with comparable countries. The move also tracks with the views of Health Secretary Robert F. Kennedy Jr., who has pushed for fewer routine childhood vaccinations and has repeatedly promoted the false claim that vaccines are linked to autism.
That claim has been rejected for years by scientists and medical authorities. FactCheck.org has documented that the idea was thoroughly discredited after large studies found no evidence that the measles, mumps and rubella vaccine, or the preservative thimerosal, causes autism. Reuters and other outlets have also reported that federal health messaging has been reshaped under Kennedy, deepening concern among doctors and researchers about the administration’s approach to immunisation.
Public health specialists warn that splitting combination vaccines could create practical barriers for families and weaken uptake at a time when measles remains a concern. Axios reported that critics, including Senator Bill Cassidy, said there is no scientific basis for separating the shots and that existing schedules have not shown increased health risks from combination vaccines. They argued that requiring extra appointments could leave more children vulnerable to preventable disease.
The order comes amid a broader effort by Kennedy to remake federal vaccine policy. According to AFP Fact Check, he has already restricted access to some Covid-19 shots, cut federal support for mRNA research and advanced renewed scrutiny of vaccine safety on the basis of claims that have been widely debunked. For critics, the new directive is less a technical adjustment than another sign that long-settled science is being placed under political pressure.
