Cutaneous adverse reactions of COVID-19 vaccines: a systematic review

Abstract

Background: Numerous vaccines are implementation for the prevention of severe course and lethal outcome of coronavirus disease 2019 (COVID-19).Objective: This systematic review aims to summarize and integrated the findings of studies regarding cutaneous side effects of COVID-19 vaccines. Methods: This systematic review conducted by searching the scientific databases of PubMed, Scopus, Science direct, and Web of knowledge from the beginning of the COVID-19 to10/5/2021. Articles were reviewed and analyzed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.Results: Seventeen studies were included after the screening of search results based on to the eligibility criteria. The results showed that injection site reactions and delayed large local reactions were the most common side effects arising from all vaccine types. Most cutaneous reactions occurred in middle-aged women, after the first dose of vaccine, and 1-21 days after vaccination. Most cutaneous reactions were self-limiting, need little or no therapeutic intervention, and were not regarded as a barrier to injecting a second dose.Limitations:Conclusion: In certain groups such as patients with allergies and a history of local injection reactions, pre-vaccination counseling and the use of appropriate medications may be helpful. However, more studies are needed to investigate the side effect profile of all COVID-19 vaccines.
