President Donald Trump signed an executive order directing the revision of childhood vaccine recommendations to favor spacing immunizations across separate appointments and exploring separate measles, mumps and rubella shots. Medical organizations and public-health experts warn that delaying vaccines could leave children vulnerable to preventable infections, while research indicates that combination vaccines improve completion rates. The order also revisits unsupported claims linking vaccines to autism, despite decades of research finding no causal connection. The directive asks the Department of Health and Human Services to review vaccine guidance, although states generally control school vaccination requirements.
