What is VAERS EXPLORER, and what is it for?

For healthcare practitioners, VAERS EXPLORER will offer a detailed analysis of symptoms and clinical syndromes of cases reported in VAERS. Real-time insight into reported cases will facilitate the detection of potential side effects in their practice and their appropriate follow-up.

• VAERS EXPLORER can also serve as a comprehensive research tool that generates reports for regulatory professionals and researchers.

• VAERS EXPLORER currently consists of a backend database of VAERS data that has data elements correlated to facilitate meaningful analysis and usability.

What is VAERS?

The Vaccine Adverse Event Reporting System (VAERS) is a U.S. national early warning system designed to detect vaccine safety issues. VAERS contains reports of adverse events from patients, healthcare professionals, and vaccine manufacturers. Manufacturers must report any side effects that come to their attention. Healthcare providers must report adverse events listed in the VAERS Table of Reportable Events Following Vaccination that occur within a specified timeframe following vaccination. The number of reports alone does not imply a causal association between a vaccine and an adverse event. The interpretation of VAERS data requires careful evaluation in the context of other scientific knowledge.

How can you currently access data in VAERS?

VAERS Data is available to the public via the web application CDC Wonder. However, CDC Wonder is not intuitive, and getting a meaningful output is difficult even for a safety professional. Knowledge of the data structure and specialized terminology is essential to interact with the data successfully.

What makes VAERS EXPLORER different?

• VAERS EXPLORER is designed as a one-stop shop for vaccine safety.

• VAERS EXPLORER makes VAERS data widely accessible and understandable by refining the data through selectable filters and producing visualizations with accompanying information tables to facilitate meaningful analysis and early indication of possible adverse events.

• VAERS EXPLORER provides additional value by providing essential resources to better judge own risk based on individual circumstances. As a result, we empower people to make informed decisions to control their healthcare better.

• VAERS EXPLORER enables patients to better engage their healthcare providers. Reports generated by VAERS EXPLORER provide comprehensive information about vaccine safety, along with data on existing case reports of adverse events and the implications/ significance in the context of their specific health profile.

• VAERS EXPLORER facilitates analysis of symptoms by organizing the data using MedDRA system organ class hierarchy, allowing intuitive orientation in most likely areas of concern.

• VAERS EXPLORER enables analysis of clinical syndromes. A combination of side effects experienced can amount to a specific diagnosis that would not be otherwise detectable.
