June 15, 2021 Share A small study offers the first hint that an extra dose of COVID-19 vaccines just might give some organ transplant recipients a needed boost in protection. Even as most vaccinated people celebrate a return to near normalcy, millions who take immune-suppressing medicines because of transplants, cancer or other disorders remain in limbo uncertain how protected they really are. It’s simply harder for vaccines to rev up a weak immune system. Monday’s study tracked just 30 transplant patients but it’s an important step toward learning if booster doses could help. It didn’t help everybody. But of the 24 patients who appeared to have no protection after the routine two vaccinations, eight of them a third developed some virus-fighting antibodies after an extra shot, researchers from Johns Hopkins University reported in Annals of Internal Medicine. And six others who’d had only minimal antibodies all got a big boost from the third dose.
