Story Summary

Researchers from the University of Missouri School of Medicine have discovered that children who receive a seasonal flu shot are less likely to suffer symptoms from a COVID-19 infection. The finding comes from a review of more than 900 children diagnosed with COVID-19 in 2020.

“It is known that the growth of one virus can be inhibited by a previous viral infection,” said Anjali Patwardhan, MD, professor of pediatric rheumatology and child health. “This phenomenon is called virus interference, and it can occur even when the first virus invader is an inactivated virus, such as the case with the flu vaccine.”
