Senator Rebukes Trump’s MMR Claims as Harmful to Immunization Confidence

Sen. Bill Cassidy denounced President Trump’s suggestion to scrap the combined MMR vaccine in favor of six separate shots, saying it would confuse parents, increase doctor visits and push up costs, ultimately harming immunization efforts. Cassidy, who voted to confirm Kennedy as health secretary, also highlighted ongoing vaccine misinformation and changes to CDC messaging about autism, noting that Trump’s comments won’t address the underlying safety concerns—even as Cassidy faces a Trump-backed primary defeat.
