A resurfaced clip from a 2020 podcast shows now Health Secretary Robert F. Kennedy, Jr. repeating several myths about flu vaccines. Kennedy claimed, without evidence, that flu vaccines “injure” the immune system and make people more susceptible to other infections, including COVID-19. The video has been viewed millions of times across multiple social media platforms and generated discussion from people who appear to believe the clip is recent. Many commenters echoed the claims, arguing that they don’t need the flu vaccine because they have never had the flu.
Recommendation
Misleading claims from high-profile figures about the safety and importance of annual flu shots may discourage vaccination. Debunking messaging may explain that statements suggesting flu vaccines increase infection risk rely on a small number of limited studies that have been refuted by more rigorous large-scale research. Health communicators may highlight that major medical organizations, including the American Lung Association and the American Heart Association, recommend flu vaccination to reduce the risk of flu infection, severe illness, and death.
Messaging may note that flu infections can cause severe illness, serious complications, and may increase the risk of heart attack and stroke, especially in older adults and young children. During the 2024-2025 flu season, low vaccination rates in the U.S. contributed to record-high child flu deaths.
