President Donald Trump signed an executive order Monday to overhaul federal childhood vaccine recommendations, narrowing the list of vaccines recommended for all children to 11 and calling for greater alignment with vaccination practices in other developed countries.

Trump Says Only 11 Vaccines Meet ‘Gold Standard’ The order divides childhood vaccines into three groups based on whether they are recommended for all children, certain high-risk groups, or shared clinical decision-making.

It identifies measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV, and varicella as vaccines recommended for all children.

The order also calls for the combined measles, mumps, and rubella vaccine to be offered as three separate shots once single-disease products are available domestically, and directs the Department of Health and Human Services (HHS) to review the timing and sequencing of childhood vaccinations.
