The millions of Americans who’ve been vaccinated are still a pretty exclusive club. That means a lot of couples, roommates and families divided into haves and have-nots, with some shifting roles, feelings and expectations. Dr. Jay Schuur, an emergency room physician, remembered a flood of relief, gratitude and hope that the needle going into his arm would be a turning point in the pandemic. He cried. Schuur’s wife, Lauraine Boccone, described the weight lifting from her shoulders. “Jay getting vaccinated for me was the relief that my partner would live,” said Boccone “because we weren’t sure in the beginning.”
