Data Source & Accuracy

  • Public Data: All data displayed comes from the publicly available VAERS database maintained by the CDC and FDA.
  • No Verification: VAERS accepts all reports without verifying medical accuracy. Reports do not prove causation between vaccines and adverse events.
  • Anyone Can Report: Healthcare providers, patients, family members, and anyone else can submit reports to VAERS.
  • Research Purpose: This data is for transparency, research, and monitoring vaccine safety signals only.

Your Privacy

  • No Personal Data Collection: This site does not collect, store, or track any personal information about visitors.
  • No Cookies: We do not use cookies except for remembering that you've seen this disclaimer (stored locally in your browser).
  • No Analytics: We do not use Google Analytics or any other tracking services.
  • Search Privacy: Your searches and filters are not logged or stored on our servers.
  • Public Data Only: The VAERS data shown here is already public and contains no personally identifiable information.

Medical Disclaimer

  • Not Medical Advice: This tool is for informational purposes only and does not provide medical advice.
  • Consult Healthcare Providers: Always consult qualified healthcare professionals for medical decisions.
  • No Liability: We are not responsible for decisions made based on this data.

Data Interpretation

  • The presence of a report does not mean the vaccine caused the adverse event.
  • Coincidental events are often reported (e.g., a heart attack that happened to occur after vaccination).
  • Serious adverse events must be reported by law, even if unrelated to the vaccine.
  • The database is useful for detecting safety signals that require further investigation.

How to Search

๐Ÿ’ก Search Tips:
  • Select Year: Choose a specific year OR "All Years" to search across all data
  • All Years requires filters: When searching all years, you must select at least one filter (lot number, vaccine type, outcome, etc.) for performance
  • Lot number tracking: Use "All Years" + Lot Number to track lots across multiple years
  • Combine filters: Use multiple filters together to narrow results (e.g., Age + Vaccine Type + Death)
  • VAERS ID: Search for specific report by ID number
  • Age: Enter exact age (e.g., 25) or decimal (e.g., 0.5 for 6 months)
  • State: Enter 2-letter state code (e.g., CA, NY, TX)
  • Vaccine Type: Search partial names (e.g., "COVID19", "FLU", "HPV")
  • Manufacturer: Search by company (e.g., "PFIZER", "MODERNA")
  • Lot Number: Search specific vaccine lot (works great with "All Years")
  • Symptoms: Search for any symptom keyword (e.g., "fever", "rash")
  • Death/Hospitalized: Filter to only show cases with these outcomes

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 "๐Ÿ“ฅ Export CSV" to download filtered data (max 10,000 records)

๐Ÿ’ก Frequently Asked Questions (FAQ)

What is this site?

๐Ÿฅ 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:

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

Limitations:

  • โš ๏ธ Reports are unverified - not investigated before publication
  • โš ๏ธ Cannot determine if vaccine caused the event
  • โš ๏ธ Underreporting - not all adverse events are reported
  • โš ๏ธ Overreporting - coincidental events may be reported
  • โš ๏ธ 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

After her second injection she immediately stated that the arm she received the injection in started... After her second injection she immediately stated that the arm she received the injection in started with unbearable pain, then terrible headache later that night. The next day was having breathing issues, had to call the rescue squad, told her to go to the hospital, became unresponsive, had to intubate her, stayed for several nights, then discharged her with adverse reaction to the vaccine, one doctor admitted it, after discharge fatigued, respiratory , vision started changed, got pneumonia in the hospital but they said was aspiration pneumonia, took a long time to see specialists like pulmonologist, 3 weeks Dec 4 visiting the mom, looked like having a stroke, went to the hospital, was stuttering really badly, started left face drooping, was fine that morning, out with her kids, went to put something in the garbage, lost her balance and realized she was not ok, felt dizzy, her grandma helped her then mouth started going numb, then couldn't talk or write, looked spacy, failed the test for a stroke, by the time she got to the hospital, couldn't recognize objects, they gave her TPA to flush out a blood clot, transferred to another hospital. Later that morning starting talking a little better, did an MRI and that was normal, says didn't have a stroke, they tried to discharge her before they even tried to get her to walk, realized she couldn't walk, Tuesday they brought her a walker and discharged her to home, dx'd with conversion disorder, Mom had to fight for her to get better care, due to lack of insurance coverage in spite of working for the federal government. once they realized things changed completely, they assumed she didn't have any coverage. Then got her PT, then stayed two more weeks, no PT though only when the requesting facility were asking for the PT notes but there were none, psychiatry came and talked to her. She says her speech was worse so hard to advocate for herself. After discharge saw two psychiatric doctors outside the hospital, they said she had depression and anxiety but only developed this due to the treatment, she says they never requested her previous records from when she was intubated, wasn't depressed then but now is depressed. Says then was still hopeful because she didn't understand the magnitude of what happened. The whole left side is in pain, the stuttering comes and goes but worse when anxious, angry, or tired, doing speech therapy, learning to slow down, Since then went to neurology who is calling it conversion disorder, has found now there are cases like hers with the same side effects. They are new to the area, found a new PCP but they never touched her after 3 visits. mom kept having to ask for help but no referrals made, the doctor only gave a few weeks off with no restrictions, doing PT, OT, ST, went to ortho who says she looks like a stroke but he felt like he couldn't go over the Neuro or PCP, needs to do EMG test prior to her next MRI.

The reporter stated that the patient was a Clinical Study participant enrolled in clinical trial for "GARDASIL 9" (however, no information regarding the study was reported). The patient's medical history was not reported. As concurrent conditions was reported "history" of heart failure. Concomitant therapies were not reported (discrepant information also reported that the patient "running out of medication" an unspecified medication). On 21-May-2025, the patient was vaccinated with the first dose of Human Papillomavirus 9-valent Vaccine, Recombinant (GARDASIL 9) (lot #Y019459, expiration date: 16-Feb-2027), dose number 1, (First Dose) (anatomical location and administration route were not reported) as prophylaxis. On 07-Jul-2025 (reported as "after a couple of weeks"), the patient experienced heart failure exacerbation. The reporting physician stated that patient was then admitted to the hospital on the same date 07-Jul-2025 for heart failure exacerbation due to "running out of medication". The reporter did not provide name of medication. During the hospitalization, some laboratory tests were performed (Aspiration of joint, blood work, X-Ray and computerized (CT) scan) but results were not provided. The patient recovered from the event on 11-Jul-2025 and was discharged from hospital on the same date. The physician stated that the event did not seem to be linked to vaccine with Human Papillomavirus 9-valent Vaccine, Recombinant (GARDASIL 9) and categorized the heart failure exacerbation as serious, however reiterated the hospitalization appears to be due to running out of medication and not linked to vaccine.; Sender's Comments: Based on the clinically relevant information currently available for this individual case, the reported event of cardiac failure is considered unlikely related to the GARDASIL 9 vaccine. The evidence is not sufficient to suggest a relationship between the vaccine and the reported serious adverse event. The causality assessment is impacted by the confounding factors of the patient's concurrent condition of heart failure and the mentioned etiology of exacerbation as being out of medication. No changes to the product safety information are warranted at this time. Merck Sharp & Dohme LLC continues to monitor the safety profile of the product More

About an hour after that, the pt called back to ask if the varicella vaccine contained any bovine or animal products. Upon research, the CDC only reported that it had aluminum salt or a form of aluminum in it. But according to the FDA, the vaccine does contain gelatin and a residual component that is made from fetal bovine. The patient has Alpha-gal syndrome that causes her to react to animal products.
