Some people who get it According to a report published in the New England Journal of Medicine, the vaccine experience of Moderna Inc. delayed eruptions that can be four inches wide or more and take about six days to resolve.
The researchers reported details of 12 cases of reactions that appeared eight or more days after people received the first dose. They were usually treated with gel and antihistamines, although some patients needed steroid treatments. About half also had skin reactions after the second dose, although they were less severe.
While there have been previous reports of reactions occurring primarily with the Modern shot, its appearance may come as a surprise. He the details should help educate physicians and reassure people who develop them, said Kimberly Blumenthal, lead author of the work and co-director of the clinical epidemiology program at Massachusetts General Hospital in Boston.

“Our goal was to show how dramatic they can be, while no one had it more serious with dose 2,” he said in an email response to the questions. “Many of the patients I cared for with this were worried about them. Is it an infection? (No!) Does that mean I can’t take dose 2? (No!) Will it happen with dose 2? (Not necessarily!) “
“This is a nuisance, but it is not dangerous,” he said in an interview.
Covid arm
Evidence of reactions appeared in previous studies. Final trial of the Moderna vaccine pointed out delayed reactions at the site of the first injection in approximately 0.8% of the 30,420 participants and between 0.2% in its second dose. They were usually resolved in about five days.
Reports of eruptions after vaccines, colloquially referred to as the “Covid arm,” began appearing on the Facebook group of pharmacists earlier this year. Pharmacists shared their experiences in the “Pharmacy Staff for Covid-19 Care” group, posting images of large red circles on their arms. People asked what community members of 44,000 people knew about the phenomenon and whether others saw similar effects.
Delayed reactions to the Modern vaccine are different from the immediate reactions at the injection site that commonly occur with both Pfizer Inc. vaccines. as with Modern messenger RNAs, Blumenthal said.
“This is a specific reaction from Moderna that appears after the first week and can last for several days,” he said. “They haven’t told me anything about Pfizer,” he said.
It is unknown exactly what is causing them, but it may be an immune reaction to the inactive components of the vaccine, he said.
Although most of the delayed reactions developed in the shoulder and upper arm near the injection site, others appeared in the elbow and fingers and palm, according to the study. . In some cases, the tissue below the surface of the skin hardened and lost its soft appearance in response to inflammation.
