When should you get your flu shot? 

Flu season typically starts in December and peaks in February, so the "optimal time" to get vaccinated is heading into the season, Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, said on "CBS Mornings" Monday.

"Before Thanksgiving, say mid-November, you want to get your flu shot, your COVID shot. But that said, whenever you can get it done, you should get it done, even if it's a bit earlier than that," Gounder said.
