Trump

President Donald Trump has signed an executive order that calls for spacing out childhood vaccines into separate medical visits and splitting the combined measles, mumps and rubella vaccine into three different single-disease shots. Trump has long suspected that the number or timing of vaccines could play a role in autism spectrum disorder, even as scientific consensus and decades of studies have firmly concluded there is no link. Childhood vaccines go through rigorous studies and safety tracking continues for years as the shots are used. The renewed focus on vaccines marks a departure from his administration’s recent efforts to emphasize less controversial health policies ahead of November's midterms. Public health experts slammed Trump's order and said the science hadn't changed.
