Flu rates are still high in Georgia this month but appear to be dropping slightly as people resume regular schedules after the winter holidays.

Vaccination remains the best way to protect against the flu, said M.G. Finn, a professor of biochemistry at Georgia Tech and an expert in viruses and immunology.

Finn said there is a gap between this year’s vaccine and the variant of flu that is circulating widely, in part because scientists design the vaccine well in advance of the flu season. Still, the vaccine reduces the risk of hospitalization by about 40%, he said, making it a valuable tool for protecting health.

“You want to bias the odds in your favor of not getting seriously ill if you happen to come across somebody who has the flu, and you want to minimize the chances of you passing it along to people around you,” Finn said. “It’s completely and utterly safe, so there is no risk whatsoever for taking it.”
