Yo-Yo Ma used the waiting time after getting his second coronavirus shot to put on a 15-minute concert

• Cellist Yo-Yo Ma put on a 15-minute concert after getting his second COVID-19 vaccine shot.
• He performed for healthcare workers in a Massachusetts vaccine site during his observation period.
• Exactly a year ago, Ma began uploading performances to help people get through the pandemic.

Renowned cellist Yo-Yo Ma performed for 15 minutes after he got his second dose of the coronavirus vaccine on Saturday.

Ma performed for workers at the Berkshire Community College in Massachusetts during his post-shot observation period, local outlet The Berkshire Eagle reported.

Richard Hall of the Berkshire COVID-19 Vaccine Collaborative told the outlet that Ma wanted "to give something back."

Exactly a year ago, Ma uploaded his first recording under the #SongsOfComfort hashtag as a means to bring people joy during the pandemic.

"In these days of anxiety, I wanted to find a way to continue to share some of the music that gives me comfort. The first of my #SongsOfComfort: Dvořák - "Going Home." he wrote in a tweet on March 13, 2020. "Stay safe."

The Eagle also reported this isn't the first time Ma has surprised essential workers by performing. In September, he and pianist Emanuel Ax played a series of surprise pop-up concerts in Pittsfield and Lee, Massachusetts.
