A Massachusetts congressman who has received both doses of the Pfizer coronavirus vaccine has tested positive for the virus. The office of U.S. Rep. Stephen Lynch said Friday that the lawmaker had had a negative test result before attending President Joe Biden’s inauguration. The office says Lynch’s positive test result came after a staff member in his Boston office tested positive earlier this week. A statement says Lynch isn’t displaying any symptoms of COVID-19. Lynch will self-quarantine and vote by proxy in Congress in the coming week.
