Adverse Events and Safety of SARS-CoV-2 Vaccines: What's New and What's Next

Kristen B Corey et al. J Allergy Clin Immunol Pract. 2022 Sep.

Abstract

Just over 1 year following rollout of the first vaccines for coronavirus disease 2019, 572 million doses have been administered in the United States. Compared with the number of vaccines administered, adverse effects such as anaphylaxis have been rare, and seemingly, the more serious the effect, the rarer the occurrence. Despite these adverse effects, there are few, if any, true contraindications to coronavirus disease 2019 vaccination and most individuals recover without further sequelae. This review provides guidance for the allergist/immunologist regarding appropriate next steps based on patient's known allergy history or adverse reaction after receipt of coronavirus disease 2019 vaccine to assist in safe global immunization.

Keywords: COVID-19; adverse effects; allergic reaction; anaphylaxis; vaccines.

Timeline of adverse reactions. The chart displays the time frame in which an individual is at highest risk of experiencing symptoms, with each of the adverse reactions discussed. It is important to note that TTS/VITT typically occurs within 1 to 2 weeks of vaccination, but the diagnostic criteria state that this may be considered for diagnosis up to 42 days after receipt of immunization. In addition, myocarditis and pericarditis may occur after first dose. SJS/TEN, Stevens-Johnson syndrome or toxic epidermal necrolysis; TTS, thrombosis with thrombocytopenia syndrome.
