Having trouble getting second COVID vaccine dose? Don't panic, officials say FacebookTwitterEmail Preston Kingswood is waiting. The Mansfield resident received his first shot of the Moderna COVID-19 vaccine during the first week of January. It went fairly smoothly, he said. “I didn’t have any issues with the shot other than a sore arm,” said Kingswood, 77, who declined to say where he received the shot. “I play trombone, and couldn’t play for three days, but other than that, there were no issues.” At the time of his vaccination, Kingswood said he also made an appointment for his second dose, which he was told was supposed to be administered within 28 days.
