Winter Vaccines for Older Adults: CDC Recommends One RSV Dose for Everyone 75 and Older, Flu Shots From 6 Months Up
The U.S. Centers for Disease Control and Prevention (CDC) restates this season's guidance on its respiratory virus vaccination page: a single dose of RSV vaccine is recommended for all adults ages 75 and older, and for adults ages 50 to 74 who are at increased risk of severe RSV; a seasonal flu vaccine is recommended for everyone aged 6 months and older; and COVID-19 vaccination is recommended for all adults ages 18 and older.
The CDC says RSV usually causes mild, cold-like symptoms but can be especially serious for infants and older adults, leading to lung infections such as bronchitis or pneumonia. The Food and Drug Administration approved the COVID-19 vaccines for the 2026-27 fall and winter virus season in August 2026.
As winter approaches, older adults can sort out all three shots in one conversation with their clinician: the RSV vaccine is currently a one-time dose rather than a yearly shot, while the flu vaccine is renewed each season. Protection for infants follows a separate path, through maternal vaccination or an infant antibody shot, as the CDC describes. (Source: U.S. Centers for Disease Control and Prevention)
