Most were being vaccinated at Massachusetts Normal Healthcare facility, the place the two the Moderna and Pfizer-BioNTech vaccines had been administered. But the delayed reactions happened only in men and women who experienced obtained the Moderna shot, Dr. Blumenthal claimed, including, “I do not recognize why.”
