A vaccine booster shot could help beef up protection against Covid-19 for some organ transplant recipients, a group fearful their suppressed immune systems may leave them defenseless as pandemic restrictions end.
A third of organ recipients who had no antibodies after their second dose developed them after a third dose, according to a small study reported Monday in the Annals of Internal Medicine. The researchers also found that participants with just a small rise in their antibodies after their two-dose regimens had higher levels after they got an added shot.
