True allergic reactions to vaccinations are extremely rare, but two local women did experience this after receiving their first dose of a COVID-19 vaccine. Allergists at Rochester Regional Health were able to safely administer their second vaccine doses by following a special procedure. Meaghan de Chateauvieux received her first dose of the Moderna COVID-19 vaccine at a Monroe County clinic in mid-January. Fifteen minutes following the injection, she was told she could go home. "And I said, 'I don't really think so,' " she recalled. Her whole body was itching and hives broke out on her arms, chest and face.
