On May 1, 2020, the U.S. Dept. of Veterans Affairs (VA) announced participation in a series of clinical trials and investigations across the nation aimed at finding ways to mitigate or potentially prevent symptoms of the coronavirus disease 2019 (COVID-19) in patients.

VAﾒs most far-reaching effort is its cooperation with the Mayo Clinic, which is studying whether blood transfusions from people who recovered from COVID-19 can help those who are still suffering with symptoms.
