This year’s flu vaccine is only 29% effective. Here’s why you still need to get that shot

Georgia Public Broadcasting reported that the 2019-2020 shot is only 29% effective. However, the CDC says some coverage is better than none, and last year’s vaccine prevented an estimated 40,000 to 90,000 hospitalizations despite being no more than 32% effective.
