Republican Senator Bill Cassidy, a physician who supported Robert F. Kennedy’s confirmation as health secretary, publicly condemned former President Donald Trump’s recent statements about MMR vaccine safety, calling them misleading and dangerous. Speaking on Sunday, Cassidy criticized Trump’s characterization of the combined measles, mumps, and rubella vaccine as potentially harmful, emphasizing that such rhetoric undermines crucial immunization efforts.
When Trump recently directed modifications to the recommended childhood vaccination schedule alongside Kennedy, the former president described MMR shots as “sort of like a nuclear weapon” that could be “quite lethal.” Cassidy, who previously chaired the Senate health committee, strongly disagreed with these claims during his CNN interview, stating that such commentary “will do nothing” to address the debunked connection between vaccines and autism.
The senator’s criticism comes amid his political challenges, including a primary loss to a Trump-backed opponent earlier this year. Cassidy has been on Trump’s list of critics since 2021, when he voted for conviction on incitement charges related to the January 6 Capitol attack. Despite these tensions, Cassidy continues to vote on key health matters, though his recent stance on Kennedy’s nomination has drawn scrutiny from medical professionals.
During his committee chairmanship, Cassidy initially supported Kennedy’s health secretary nomination after securing promises to maintain CDC vaccine information resources. However, following Kennedy’s appointment, the CDC’s “Autism and Vaccine” webpage was modified to include language that some interpret as validating vaccine-skeptic perspectives. New sections now suggest the absence of evidence linking vaccines to autism lacks a definitive research basis, and imply that supportive studies may have been overlooked by health authorities.
Cassidy expressed concern that Trump’s recent comments about requiring six separate vaccinations instead of two MMR doses would increase healthcare costs and inconvenience families. He explained that parents would face more clinic visits, children would receive additional injections, and insurance companies would cover more appointments—ultimately raising premiums. The former senator emphasized that these changes serve no public health benefit while creating practical burdens for families and medical systems.
