Senator Bill Cassidy has voiced strong opposition to President Donald Trump’s recent decision to split the measles, mumps, and rubella vaccine into three separate shots. Cassidy said the move would increase both time and cost for families, as parents would need to take their children to the doctor six times instead of just twice. He added that insurance companies would now pay for six visits rather than two, which could raise premiums and hurt affordability.
The Louisiana Republican also pointed out that children would receive more injections, which could be harder on them and their families, according to The Hill. Cassidy argued that this approach runs counter to the goal of making vaccines accessible and affordable for all Americans. He said the president’s approval ratings are likely suffering because of such policies.
Cassidy described the plan as a step backward in public health efforts. The move follows broader actions by Trump and Health and Human Services Secretary Robert F. Kennedy to reshape childhood vaccination guidelines. It also includes a directive for HHS to improve vaccine safety research, with an emphasis on autism and the discredited link between vaccines and the condition.
Medical professionals have strongly criticized splitting up the MMR vaccine, warning it leaves children more vulnerable to diseases. Doctors recommend that children receive the combined MMR shot twice — once between 12 and 15 months, and again at 4 to 6 years, according to a report from Yahoo News. This combined vaccine has been available since 1971, developed by Dr. Maurice Hilleman.
The varicella vaccine was added in 2005 to create the current MMRV combination. Cassidy also noted that the idea of splitting vaccines goes against the convenience and efficiency that families expect. He emphasized that parents are already stretched thin, and this change makes their lives harder.
The senator’s comments come after changes made to the CDC website under Kennedy’s leadership, The Guardian reported. That page was updated to question the scientific consensus on vaccines and autism, which many experts have said is not supported by evidence. Cassidy stated that Trump’s remarks about vaccines will not help resolve the confusion around autism and immunization.
He pointed out that the original claims linking vaccines to autism were based on a single paper that was later retracted. The senator’s criticism highlights growing concerns about how political decisions affect public health guidance.
