The Food and Drug Administration released its recommendations Thursday for the composition of next season’s influenza vaccines, marking a departure from its usual process by bypassing input from external advisers.
The agency’s guidance came after internal discussions with officials from the Centers for Disease Control and Prevention and Department of Defense, following the unexpected cancellation of a planned March advisory committee meeting. The FDA advised manufacturers to produce trivalent vaccines targeting the H1N1, H3N1, and B/Victoria influenza lineages, maintaining consistency with the previous year’s
recommendations.
The cancellation of the advisory meeting has sparked concern among public health experts, particularly in light of newly appointed Health Secretary Robert F. Kennedy Jr.’s history of questioning established vaccine protocols. The development follows a similar postponement of a CDC vaccine advisory panel meeting.
During recent Senate health committee hearings, lawmakers pressed FDA commissioner nominee Marty Makary about the canceled meeting, expressing worries about diminished transparency in the vaccine selection process. While Makary denied involvement in the cancellation decision, he indicated he would reassess which topics require advisory committee consultation if confirmed. The committee subsequently voted 14-9 to advance his nomination to the full Senate.
If confirmed, Makary would report to Kennedy, whose appointment has generated controversy due to his long-standing skepticism toward vaccines. Kennedy has notably promoted theories linking vaccines to autism, despite numerous studies finding no such connection. Reports indicate the CDC is planning to investigate this claimed association, which has become a priority for the White House’s Make America Healthy Again Commission.
The FDA expressed confidence that there will be sufficient and varied supply of approved trivalent seasonal influenza vaccines available for the 2025-2026 U.S. flu season. This assurance comes amid broader concerns about vaccine policy under the current administration.
The situation has taken on added significance against the backdrop of a measles outbreak in Texas, where the first death from the disease since 2015 was recently documented. While Kennedy has publicly encouraged people to discuss vaccination with their healthcare providers, he continues to characterize vaccination as a matter of personal choice and has promoted alternative viewpoints about vaccine safety.
The agency’s decision to proceed with vaccine strain recommendations without external advisory input represents a significant shift in established protocol. Traditionally, these recommendations have been made following consultation with outside experts and in alignment with international guidelines.
Health officials maintain that the selected strains were chosen based on comprehensive analysis of currently circulating influenza variants and the effectiveness of existing vaccines. However, the deviation from standard procedures has intensified debate about the
administration’s approach to vaccine policy and public health decision-making.
The development occurs during a period of heightened scrutiny of vaccine policies and amid evolving public health challenges. The intersection of scientific consensus, public health policy, and political leadership has become increasingly complex, particularly regarding immunization strategies and their implementation.
Kennedy’s leadership of the Department of Health and Human Services has introduced new dynamics to vaccine policy discussions, with his stated positions on vaccine safety and efficacy potentially
influencing the broader public health landscape. As these changes unfold, medical professionals and public health experts continue to monitor their potential impact on vaccination programs and public health outcomes.
