Editorial: What Can be Learned from National and International Vaccine Adverse Event Reporting Systems During the COVID-19 Pandemic?

Healthcare professionals have an ethical, medico-legal, and professional responsibility to report all suspected adverse events following immunization to relevant national reporting agencies as part of the process of post-marketing drug safety monitoring. In the US, the Vaccine Adverse Event Reporting System (VAERS) is co-sponsored by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA). Data from VAERS and other national and global reporting systems show very low rates of adverse events related to currently approved SARS-CoV-2 vaccines. Populations studies have supported the findings from adverse event reporting systems. The presentation, monitoring, and reporting of adverse events related to SARS-CoV-2 vaccines may have future applications in vaccine monitoring for several other potential pandemic zoonotic infections. This editorial aims to summarize the current understanding of adverse events from current COVID-19 vaccines from global adverse event reporting systems, rather than individual case reports or anecdotal reporting in the media.
