Some people who get Moderna Inc.’s vaccine experience delayed rashes that can be four inches wide or more and take around six days to resolve, according to a report in the New England Journal of Medicine.
Researchers reported details on 12 cases of reactions that appeared eight or more days after people received their first dose. They were typically treated with ice and antihistamines, although some patients needed steroid treatments. About half also got skin reactions after the second dose, though they were less severe.
