US Minister of Health Robert F. Kennedy Jr. fired all 17 members of the CDC's Advisory Committee on Immunization Practices (ACIP). Eight of those members were appointed in January 2025 by President Joe Biden. The committee issues official vaccination recommendations that are rarely overruled by the CDC director. Kennedy justified the change by trying to restore public confidence in vaccine science and prioritize evidence-based medicine. The new members include scientists who previously questioned the effectiveness of vaccines. The committee unanimously changed the recommendation for vaccination against covid-19: instead of the annual vaccine for everyone from 6 months of age, it recommends a consultation with a doctor. By a vote of 8 to 3, he decided to limit the hepatitis B vaccine in newborns to high-risk cases only. Kennedy withdrew $500 million earmarked for vaccine development.
