Does the Flu Shot Work Against This Year's Strain?

Joe Gastaldo, MD, OhioHealth Infectious Disease specialist, shares if this year’s flu shot works against this year’s strain.

This year’s flu shot is a bullseye. When we put the flu shot together in the spring before the following flu season, professionals make the best guess of what is going to be the predominant circulating strain. Currently the predominant circulating strain is influenza AH3N2 and that’s part of this season’s flu shots.

Remember: if you get the flu shot, you have a great layer of protection against severe disease resulting in hospitalization or death.
