Cutaneous reactions associated with vaccination against SARS-CoV-2.

ABSTRACT

BACKGROUND: Since the first reports in November 2019, coronavirus 2 has represented a priority health problem causing severe acute respiratory syndrome and other extrapulmonary manifestations, originating a pandemic with millions of deaths. Therefore, vaccines represent the most effective means of controlling the COVID-19 pandemic. Skin reactions to COVID-19 mRNA vaccines have been observed. The objective of this paper is to evaluate the morphology of the cutaneous manifestations and to carry out a review on the current recommendations for their management. CLINICAL CASE Case 1 A 25-year-old male patient who presented a morbilliform rash after the first dose of the Pfizer vaccine against SARS-CoV-2, which remitted without sequelae at 24 hours. Case 2 A 65-year-old female patient with erythema at the puncture site 10 days after the first dose of the Modern vaccine against SARS-CoV-2 with complete remission on the 4th day after its onset. CONCLUSION(S) Some of the dermatological manifestations to the mRNA COVID-19 vaccines were identified as mimicking the SARS-CoV-2 infection itself. As the administration of vaccines increases, it is essential to recognize and understand their adverse effects.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V.. All rights reserved.
