Vaccine Adverse Event Reporting System (VAERS)

De-identified post-licensure vaccine adverse event reports from the CDC and FDA as downloadable raw data tables.

About

The Vaccine Adverse Event Reporting System (VAERS) is the national early warning system co-managed by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) to monitor the safety of vaccines after authorization. VAERS accepts spontaneous reports of suspected adverse health events following vaccination from healthcare providers, manufacturers, and vaccine recipients, publishing anonymized tabular data packages.

Through Fibric, an operator references vaccine adverse event signals and administration safety profiles, proposing occupational health review flags, worker safety committee agendas, and clinical health documentation audits across corporate healthcare environments.

This is a reference listing. It documents what Fibric would read from Vaccine Adverse Event Reporting System (VAERS) and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • De-identified patient reports of post-vaccination adverse events from healthcare providers and recipients
  • Vaccine product details including vaccine type, manufacturer, brand name, lot number, and administration route
  • Reported clinical symptom terms encoded using the Medical Dictionary for Regulatory Activities (MedDRA)
  • Patient demographic categories including age groups, biological sex, and reported medical history
  • Downloadable annual and monthly cumulative CSV datasets hosted on vaers.hhs.gov

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Monitor vaccine safety signals for occupational health compliance

    Analyze VAERS adverse event reports for workplace-recommended vaccines, proposing updated employee consent forms and clinical advisory summaries for corporate health clinics.

    With Compliance Evidence, Shift Coverage

  • Review lot-specific adverse event reports against administered supplies

    Cross-reference employee health clinic vaccine lot records against VAERS product tables, proposing quality holds if specific manufacturing lots show statistical clustering of reports.

    With Lot Quarantine, Quality Hold

Requirements

  • Data parsing pipeline capable of processing large multi-gigabyte relational CSV tables (VAERSDATA, VAERSVAX, VAERSSYMPTOMS)
  • MedDRA clinical terminology crosswalk to map symptom codes to standardized medical categories
  • Adherence to HHS data use disclaimer prohibiting attempts to re-identify individual reporters or patients
Authentication
None. Raw VAERS data packages are openly downloadable from the VAERS public portal without authentication or API credentials.

Limits

  • VAERS is a passive reporting system subject to underreporting, duplicate submissions, and unverified clinical narratives
  • Reported events indicate temporal association following vaccination and do not establish medical causality
  • Raw data packages update periodically with a four-to-six week processing delay after report receipt

Questions and answers

What agencies operate the VAERS database?
VAERS is co-managed by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA).
Does a VAERS report mean a vaccine caused the adverse event?
No. VAERS is a spontaneous reporting surveillance system. A report indicates an event occurred after vaccination, not that the vaccine caused it.
How is VAERS data distributed?
Data is published as downloadable ZIP archives containing three relational CSV files: event data, vaccine data, and MedDRA symptom tables.
