CDC panel recommends multiple shots for measles, mumps, rubella and chickenpox instead of single vaccine

Experts react with concern that increasing the number of vaccinations required will threaten children’s health

A powerful vaccines committee for the US Centers for Disease Control and Prevention (CDC) voted on Thursday to change US vaccine policy and start recommending that children receive multiple vaccines to protect against measles, mumps, rubella and chickenpox, instead of a single vaccine that can protect against all four diseases.

The new recommendations from the panel, the advisory committee on immunization practices (ACIP), arrived just one day after top former CDC officials said that Robert F Kennedy Jr was a threat to US children’s ability to receive vaccines on schedule. The committee’s work typically determines which vaccines are provided free of charge through the US government, shapes state and local laws around vaccine requirements, and influences which vaccines health insurers tend to cover.
