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.
