Yes, It Is Possible To Get Your Flu Shot Too Soon

“It’s a way to get people into the store to buy other things,” Charland says.

But some doctors warn the marketing may be overtaking medical wisdom, since it’s unclear how long the immunity imparted by the vaccine lasts, particularly in older people.

Federal health officials say it’s better to get the shot whenever you can. An early flu shot is better than no flu shot at all. But the science is mixed when it comes to how long you’ll get optimal protection from a flu shot promoted and given during the waning days of summer; the typical flu season peaks in mid-winter or beyond.

“If you’re over 65, don’t get the flu vaccine in September. Or August. It’s a marketing scheme,” says Laura Haynes, an immunologist at the …
