Flu shots provide moderate protection against COVID-19 infection and could reduce the risk of hospitalization and mortality from the illness, according to a recent study.
The Oct. 31 preprint study, published on MedRxiv, looked at data from 210,136 individuals to estimate the effectiveness of influenza vaccine (flu shot) against COVID-19 infection during the Delta and Omicron waves. The study found that taking an influenza vaccine provided “moderate protection” against COVID-19 infection.
