The WNBA is officially fully vaccinated.

To celebrate the milestone, the WNBPA has released a “FULLY VAXXED” T-shirt, with a portion of proceeds going to Black Girls Do STEM.

The WNBPA told Just Women’s Sports that the players credit Elizabeth Williams for the success of the league’s vaccination effort, which included educational zoom sessions with physicians, mental health professionals and epidemiologists.

Williams’ research and commitment to understanding vaccine science has earned her the unofficial moniker “Chief Health Officer” of the WNBPA.

Williams comes from a family of doctors and reportedly plans to go to medical school when she’s done playing hoops.
