Sixty-eight-year-old Melvin King was visibly elated. As the sticker on his chest declared, he had just received his COVID-19 vaccine.
“My second one, as a matter of fact,” he said. “I’ve been looking forward to it, you know, and I think, you know, that this is very important to everyone, not just to myself.”
King’s primary care doctor here, at Healthcare for the Homeless in Baltimore, called him to make the appointment.
