Coronavirus survivor: 'In my blood, there may be answers'

Hospitals are starting to line up survivors of the new coronavirus to donate some blood, so doctors can use it to treat the sick. Blood plasma from recovered COVID-19 patients carries immune system antibodies that fight the virus, and early donors are happy to try to help. It's experimental, but the century-old treatment has helped fight other diseases in the past including the 1918 flu pandemic. The Food and Drug Administration Friday announced a national study to help more hospitals try the approach and sign up more people. Researchers will track whether the experimental therapy really works.
