TENNESSEE, USA — A Tennessee state senator is participating in a COVID-19 vaccine trial.
Sen. Richard Briggs, who represents Knoxville, said he is taking part in the phase three trial at Vanderbilt University Medical Center.
The senator, who is also a surgeon, said he is one of the first volunteers to receive an injection.
The study will evaluate the effectiveness of the experimental COVID-19 vaccine, compared to no vaccine.
