Almost all severely allergic people could complete 2 dose COVID vaccine protocol: JAMA
BOSTON - Nearly all healthcare workers at a Boston healthcare system who reported severe allergic reactions after receiving a COVID-19 mRNA vaccine were able to safely complete the series.
The study of employee vaccinations within the Mass General Brigham health care system revealed that although people with such a history reported more allergic symptoms after vaccination, nearly all of them were able to become fully vaccinated.
New research addressing ongoing concerns regarding risks of allergic reactions after receiving mRNA COVID-19 vaccines, particularly for individuals with a history of severe allergic reactions has been published in the JAMA Network Open.
In the study of 52,998 health care employees, 474 (0.9%) reported a history of severe allergic reactions to medications, vaccines or allergens. Survey results showed that 11.6% of employees with this history reported allergic reactions after receiving dose 1 or 2 of a COVID-19 mRNA vaccine, compared with 4.7% of employees without this history. High-risk allergy history was associated with a 2.5-times increased relative risk of allergic reactions, with the highest risks for hives and angioedema. However, despite these symptoms, 5,1706 employees (97.6%) received 2 doses of an mRNA COVID-19 vaccine.
