Advisory Committee on Immunization Practices (ACIP)

The Advisory Committee on Immunization Practices (ACIP) had its members replaced by the secretary of Health and Human Services, disrupting its processes and influencing immunization practices. The Centers for Disease Control and Prevention's scientific experts' participation was limited, and the Food and Drug Administration's liaison representative was replaced. This has impacted the credibility of the CDC's vaccine advisory committee.

Maryland Governor Wes Moore signed the Vax Act, shifting vaccine guidance authority from the CDC's Advisory Committee on Immunization Practices (ACIP) to the state's health secretary. The law mandates state-level recommendations for immunizations, screening, and preventive services, marking a departure from federal guidelines.
