A recent study found that one shot of the RSV vaccine can protect adults for two RSV seasons.

VUMC News reports that RSV, or respiratory syncytial virus, causes 100,000 to 150,000 hospitalizations and 4,000 to 8,000 deaths yearly among adults ages 60 and older. The Centers for Disease Control and Prevention recommended the RSV vaccination for adults 60 and older beginning in June 2023. Vanderbilt University Medical Center partnered with the CDC to study the vaccine in 19 states between October 2023 and March 2024, and first confirmed its effectiveness in the fall of 2024.
