Disclaimer: Before using this website, please ensure that you have read, understand, and agree on the VAERS disclaimer shown at: https://vaers.hhs.gov/data.html. As described in the indicated CDC/FDA VAERS Disclaimer, the VAERS data largely came from voluntary reporting. It has the advantage of nation-wide reporting and can provide some early warning of potential safety issue(s) with a vaccine. However, the VAERS "Reports may include incomplete, inaccurate, coincidental and unverified information". In addition, the VAERS data alone cannot be used to determine the causality of the identified vaccine adverse event. Instead of being causal, it only shows statistical association based on our statistical data analysis pipeline.

Provenance: The data in Cov19VaxKB were originally extracted from the VAERS database on July 23, 2022 (Note: The data contains VAERS reports processed as of July 15, 2022).
