Skin allergies after COVID-19 vaccination rare, recurs seldomly after second doses: JAMA
Skin reactions were reported by 776 (1.9%) of survey respondents after the first dose. Boston: Skin reactions after mRNA COVID-19 vaccination are rare and even when they do occur after the first dose, they seldom recur after a second vaccine dose, finds a recent study.
Skin problems such as itchiness, rashes, hives and swelling can occur in some individuals after receiving a COVID-19 vaccine, but it's not clear how common these reactions are or how frequently they recur with a subsequent vaccination. Research led by allergists at Massachusetts General Hospital (MGH) now provides encouraging indications that the reactions are rare, and that even when they do occur with an initial COVID-19 vaccination, they seldom recur after receiving a second vaccine dose.
For the study, a team led by Kimberly G. Blumenthal, MD, MSc, co-director of the Clinical Epidemiology Program within MGH's Division of Rheumatology, Allergy and Immunology, prospectively studied 49,197 Mass General Brigham employees who received mRNA COVID-19 vaccines. At least one symptom survey was completed by 40,640 employees after the first dose of vaccine.
Skin reactions were reported by 776 (1.9%) of survey respondents after the first dose. Rash and itching (other than at the injection site) were the most common skin reactions, and the average age of those reporting skin reactions was 41 years. Skin reactions were more common in females (85%) than males (15%) and differed by race (62% white, 7% Black, and 12% Asian).
