I got it, a week ago now. This time, my arm isn’t even sore. After the first one, I woke up two days later, with a piercing headache, nausea, and a fatigue so overwhelming that I spent the afternoon napping and went to bed at 7:30, my body so leaden it was hard even to move. The next day, I was totally fine.

On our daily walks, we meet neighbors with whom all conversation centers around “the shot.”

“When are you getting yours?”
