Is my immunity waning? Doctors advise Pfizer vaccine recipients not to worry
CNN
Yes, your immunity is probably waning. No, it's not time to storm the pharmacies for boosters.
While getting two doses of vaccine creates a strong immune response that reduces the risk of severe disease by more than 90%, the protection against milder and asymptomatic infections drops off gradually.
That's why Pfizer has asked for and received US Food and Drug Administration authorization to add boosters for many people who are six months out from vaccination.
