Boston Marathon organizer says 93 percent of participants are vaccinated against COVID-19

October 11, 2021

The Boston Athletic Association required all participants in the 2021 Boston Marathon to be either fully vaccinated against COVID-19 or test negative ahead of the race Monday — and it appears the vast majority chose the first option.

BAA CEO Tom Grilk said Monday on WBZ that 93 percent of the runners Monday have been vaccinated, and almost all the others tested negative for COVID-19. According to Grilk, 0.3 percent of those tested had positive results, barring them from the race. Boston.com
