Scientists are beginning a new study to tell if the blood plasma of COVID-19 survivors might help prevent infection in the first place.
Doctors already are using survivor plasma as a treatment for many hospitalized patients, even as research still is underway to tell if it really works.
The plasma harbors virus-fighting antibodies. Researchers at Johns Hopkins University are testing if giving that immune system boost to people newly exposed but not yet sick - like health workers or nursing home residents - could help stave off illness.
