Should you get a booster shot? Experts say it's time

The question has been hotly debated for months but over the last week, a larger pro-booster consensus has formed.

Millions more vaccinated adults across the U.S. became eligible for a COVID-19 booster shot on Friday. And yet, the vast majority of vaccinated Americans were already eligible -- many just didn't know it.

According to an October survey from the Centers for Disease Control and Prevention, 4 in 10 vaccinated adults were unsure if they qualified for a booster. So far, just 32 million Americans have received a booster, or around 18% of the more than 182 million adults who are fully vaccinated.

In announcing the latest recommendations, public health experts at the Food and Drug Administration and the CDC expressed hope that they would cut through the confusion, simplifying the decision for Americans who are wondering: Do I need a booster shot?

Here's what the experts say.
