The authors of this editorial discuss the observations of adverse advents reported in recipients of the various vaccines against SARS-CoV-2, particularly those involving thrombosis and thrombocytopenia.
They pose questions involving clinical implications that warrant further research and emphasize the very low prevalence of some of these adverse events relative to the benefits of preventing COVID-19.
This abstract is available on the publisher's site.
The coronavirus disease 2019 (Covid-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stimulated the development of highly effective vaccines that were produced with unprecedented speed with the use of diverse technologies. No major safety warnings, other than rare cases of anaphylaxis, were reported in the initial trials, which involved tens of thousands of adults, and the risk of serious adverse effects has remained remarkably low after vaccination of more than 400 million people worldwide to date. It is not surprising, however, that new reports of adverse events have emerged as many additional people are vaccinated and follow-up is extended. For example, cases of immune thrombocytopenia and bleeding without thrombosis that were induced or revealed after exposure to the messenger RNA (mRNA)–based vaccines produced by Moderna (mRNA-1273) and Pfizer–BioNTech (BNT162b2) have been reported.
