The wide-ranging order proposes reducing the total number of immunizations recommended for children in their earliest years and dividing the nation’s childhood vaccine schedule into three categories. Under the order, the administration’s new policy states that all children are recommended to receive vaccines for measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV and varicella, or chicken pox. That marks a change from the current schedule, which recommends that all children receive most of those shots. Trump’s announcement hews closely to an HHS effort in January to whittle down the number of recommended vaccines in the childhood schedule. The Monday order on vaccines followed months of escalating pressure that Trump had put on Kennedy for more action on the childhood vaccine schedule, as the two men both publicly speculate about links between vaccines and autism.
