Pfizer Says People Who Got Coronavirus Vaccine May Need Booster Shot

It’s one of the biggest questions people have about the Coronavirus vaccine: will people who are vaccinated need a booster shot? Pharmaceutical company Pfizer has asked the Food and Drug Administration to approve a third shot of its Covid vaccine for use as a booster. But the FDA and the CDC issued a joint statement saying that at this time, no booster shot is needed. Many experts want to make sure that as many people as possible get a first vaccination.
