SAN DIEGO — U.S. Health Secretary Robert F. Kennedy Jr. has overseen the cancellation of major mRNA vaccine contracts, the dismantling of universal vaccine recommendations, and cuts to government funding for vaccine research. These actions occurred during his tenure leading the department. Kennedy, who serves as the current Health Secretary, has been identified as a longtime critic of vaccines. The policy shifts mark a significant change in the department's approach to immunization programs and research funding under his leadership. Reports indicate that the cancellation of contracts and reduction in funding were implemented as part of the broader policy changes initiated since he took office. The dismantling of previous universal recommendations aligns with Kennedy's historical stance on vaccine issues. Observers note that these moves represent a departure from prior administration policies regarding public health immunization strategies. The combination of contract cancellations, funding cuts, and policy dismantling constitutes the primary administrative actions taken by Kennedy in his role as Health Secretary regarding vaccine programs.
