A survey of allergists at Massachusetts General Hospital indicates that skin reactions are rare after the first dose of COVID-19 vaccine and rarely reappear after the second dose. Skin problems like itchiness, rashes, hives and swelling can occur, but in a few cases.
In the study, 49,197 people received mRNA vaccines. Skin reactions were reported by only 776 (1.9%) of respondents after the first dose. Rash and itching were the most common skin reactions and the mean age of people reporting skin reactions was 41 years. Skin reactions were more common in women (85%) than men (15%) and differed by race (62% white, 7% black, and 12% Asian).
Of those who reported skin reactions to the first dose, received a second dose, and completed a symptom survey after the second dose, 83% reported no recurrent skin reactions.

Among individuals without a skin reaction to the first dose, 2.3% reported skin reactions after the second dose, with rash and pruritus being the most common.
For scientist Lacey B. Robinson, skin reactions should not be a reason not to take the second dose because most do not reappear with the next dose. Robinson explains that anyone who has reactions hours after vaccination or severe reactions at any time should consult an allergist or immunologist to evaluate and advise on the 2nd dose vaccination.
