When world-renowned cellist Yo-Yo Ma received his second dose of the Covid-19 vaccine on March 13th, he transformed his 15-minute observation period following the jab into a powerful performance for others in the waiting area. Wanting to give back, he sat masked and socially-distanced with his cello, and playing music for 15 minutes to an applauding audience at the end of a full day of vaccinations. "What a way to end the clinic," wrote Richard Hall of the Berkshire Covid-19 Vaccine Collaborative in Massachusetts. Incidentally, the day also happened to be exactly one year after Yo-Yo Ma posted his first recording under the hashtag #SongsOfComfort with the intention to bring solace and connection to a world grappling with uncertainties of pandemic. In September 2020, the distinguished musician also surprised essential workers with a series of pop-up concerts.
