Download Older VAERS Data

Those who want to do serious analysis of the VAERS data and are willing to work with older releases can download a Microsoft Access file with all of the data up to the end of 2020. Unfortunately, VAERS grew so much in 2021 that it exceeded the maximum size allowed for an Access file (two gigabytes). As a result, it is no longer possible to build a VAERS Access file anymore.
