Understanding the Data

• Reports are unverified: VAERS accepts all reports without medical verification
• Not proof of causation: A report does not mean the vaccine caused the event
• Anyone can report: Healthcare providers, patients, and family members can submit reports
• Multiple vaccines: One report may list multiple vaccines given at the same time
• Blank fields: Not all fields are required, so some data may be missing

Using the Table

• Sort columns: Click column headers (ID, Age, Sex, Date, Died) to sort
• Expand text: Click "More" to see full narrative or symptom text
• Navigate pages: Use pagination controls at top and bottom of table
• Export results: Click "📥 Export CSV" to download filtered data (max 10,000 records)

What is this site?

🏥 VAERS Vaccine Data Browser is an independent, third-party data browser for publicly available VAERS (Vaccine Adverse Event Reporting System) data.

Important: This site is NOT affiliated with, endorsed by, or operated by the CDC, FDA, or any government agency. We are an independent service that makes public VAERS data easier to search and analyze.

What is VAERS?

VAERS (Vaccine Adverse Event Reporting System) is a national early warning system established in 1990 to detect possible safety problems with vaccines. It's co-managed by the CDC (Centers for Disease Control and Prevention) and FDA (Food and Drug Administration).

VAERS accepts and analyzes reports of adverse events (possible side effects) after a person has received a vaccination.

Official VAERS website: vaers.hhs.gov

Is this data HIPAA compliant?

Yes, absolutely. All VAERS data displayed here is:

• Publicly available - Published by the CDC/FDA on their official website
• De-identified - Contains no personally identifiable information (names, addresses, contact info removed)
• Legally accessible - Available to researchers, media, and the general public under FOIA (Freedom of Information Act)
• Not protected health information - Once de-identified and published by the government, it's no longer covered by HIPAA restrictions

This site displays the same public data available at vaers.hhs.gov/data.

Why does this site exist?

We believe in transparency and public access to health data. While the CDC/FDA provide VAERS data, their official site:

• Is difficult to search and filter
• Requires downloading large CSV files and technical knowledge
• Is not user-friendly for the average person

This independent site makes the same publicly available data easier to search, filter, and understand for researchers, journalists, healthcare workers, and concerned citizens.

Where does the data come from?

All data is downloaded directly from the official CDC/FDA VAERS website at vaers.hhs.gov/data.

The data is:

• Publicly released by the CDC/FDA every week
• Available as downloadable CSV files
• Imported into this site's database for easier searching
• Displayed exactly as provided (no modifications or filtering)

This site does not collect, modify, or add to the official VAERS data.

My vaccine lot number matches one with deaths/serious events - should I be worried?

Important context:

• VAERS reports do NOT prove causation - A report means an event occurred after vaccination, but doesn't mean the vaccine caused it
• Anyone can report - Reports are not verified for medical accuracy before being published
• Coincidences happen - When millions of people get vaccinated, some will experience unrelated medical events afterward
• Large lot numbers - Popular vaccines may have hundreds of thousands of doses from one lot number
• More vaccinations = more reports - Lots used widely will naturally have more reports

What to do:

• Don't panic - VAERS data requires expert analysis to interpret
• Talk to your doctor if you have concerns
• Check official CDC/FDA safety communications for genuine safety signals
• Remember: billions of vaccine doses have been safely administered

Can I trust VAERS data?

VAERS is valuable but has limitations:

Strengths:

• ✅ Early warning system for potential safety signals
• ✅ Open and transparent - publicly accessible
• ✅ Accepts all reports regardless of likelihood of causation
• ✅ Monitored by CDC/FDA experts who investigate concerning patterns

Limitations:

• ⚠️ Reports are unverified - not investigated before publication
• ⚠️ Cannot determine if vaccine caused the event
• ⚠️ Underreporting - not all adverse events are reported
• ⚠️ Overreporting - coincidental events may be reported
• ⚠️ Incomplete data - not all fields are required

Bottom line: VAERS is an important tool for safety monitoring, but individual reports should not be used as proof that a vaccine caused harm.

What are "adverse events"?

An adverse event is any undesirable health occurrence that happens after vaccination, including:

• Common reactions: Sore arm, mild fever, fatigue (usually expected)
• Serious events: Hospitalization, disability, life-threatening illness, death
• Coincidental events: Medical conditions that would have occurred anyway

Important: An adverse event doesn't mean the vaccine caused it - only that it occurred after vaccination. Many reported events are coincidental or unrelated.

Why are some lot numbers listed multiple times?

This is normal and expected! A person may receive multiple doses of the same vaccine from the same lot number:

• COVID vaccines require 2-3 doses
• HPV, Hepatitis B, and other vaccines have multi-dose schedules
• Each dose is recorded as a separate entry

Example: Person receives Pfizer COVID dose 1 (lot ABC123) and dose 2 (lot ABC123) - lot ABC123 appears twice in their report.

How often is this data updated?

The CDC/FDA releases new VAERS data every Friday. This site is typically updated:

• Weekly or bi-weekly for recent data
• Check the available years to see what data is currently loaded
• During updates, the site may be in maintenance mode temporarily
