When to get the flu shot and more to know about influenza in 2021

The COVID-19 pandemic continues on as we head into the colder months, but there's also another seasonal illness to remember: the flu. 

Flu vaccines and nasal sprays have been available for protection against strains of the virus since the summer, and the Centers for Disease Control and Prevention recommends that people should be vaccinated by the end of October for the best protection this season.

Last year, activity for the 2020-21 flu season was unusually low, with the CDC postulating vaccines and COVID-19 mitigation measures, including wearing face masks, staying home, hand washing, school closures, increased ventilation of indoor spaces, reduced travel and physical distancing may have contributed to the decline in illness, hospitalization and deaths from the flu virus.

Additionally, a record number of flu vaccine doses were given in the U.S. during 2020 and 2021 – 193.8 million doses.
