As the flu season approaches and coincides with millions of Americans newly eligible for the Pfizer-BioNTech COVID-19 vaccine booster, with expert backing for boosters developed by Moderna and J&J, many may wonder whether it’s safe to receive both a booster and a flu vaccine in one visit.

Tim Mack, 56-year-old of New York City, told Fox News that he recently received his COVID-19 vaccine booster and flu shot on the same day.

Mack, who has an underlying health condition, said he had the typical soreness from the injections, but didn’t feel as though the flu shot worsened any of the usual side effects from the COVID-19 vaccine.

"I felt a little tired, but not anything more than I had with the second COVID vaccine shot," Mack told Fox News, adding that he wanted to receive both shots at the same time due to upcoming family events and holidays.

Health officials urge vaccination against both diseases; the COVID-19 vaccine does not protect against the flu, and the flu vaccine will not protect against COVID-19, Denise Walsh, dean of the school of health professions and nursing and chief global health officer at Long Island University, reiterated. 

"Getting a flu vaccine is the best protection against flu and its potentially serious complications, and getting a COVID-19 vaccine is the best protection against COVID-19," per the CDC webpage, which advises patients with any questions to consult their healthcare provider
