The US Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices (ACIP) is facing upheaval. Secretary Robert F. Kennedy Jr. dismissed all 17 previous members and appointed eight new ones, sparking concerns about the committee's expertise and potential conflicts of interest. Public health experts warn of potential "vaccine chaos" due to inconsistent recommendations and access. The changes have prompted some states to remove ACIP references from vaccine access laws, while other groups seek to create alternative evidence-based recommendations. The new ACIP's first meeting is generating significant worry over the future of vaccine policy in the US.
