The Vaccine Adverse Events Reporting System (VAERS) is a national early warning system to detect possible safety problems in U.S. licensed vaccines. Reporting is voluntary. A study for U.S. Department of Health and Human Services concluded less than 1% of vaccine adverse events are reported. VAERS is a passive reporting system, meaning it relies on individuals to send in reports of their experiences to CDC and FDA. VAERS can provide CDC and FDA with valuable information that additional work and evaluation is necessary to further assess a possible safety concern. VAERS data is primarily from the United States. Approximately 10% of the reports are from nondomestic sources. These are denoted as FR in the VAERS State field.
The OpenVAERS Project was created because the HHS VAERS site is difficult to navigate and for the public to obtain useful information from. This project allows the public to browse reports. The data is not changed, modified or vetted. The data is downloaded/formatted for easier browsing allowing others to obtain quick accurate information. There are mistakes in the data but these are presented as obtained directly rom VAERS (impossible dates are usually the most obvious).
The “Red Page Summary” pages are presented here as they are especially useful for quick monitoring of all Covid Vaccine data and are updated frequently. The individual reports follow the summary.
