About This Site

This is a public data browser for the Vaccine Adverse Event Reporting System (VAERS). By using this site, you acknowledge and agree to the following:

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

It bounced from 120s to 50s and back within a couple minutes, and did so for 5 hours (7 pm - midnight). When I realized why it was happening, likely vaccine reaction, I decided to wait and see what happened. I had just received thorough heart tests in March with good results. But if it had gone on for much longer I would have gone to ER. Told my family doctor, Dr, at appointment this week. Plan to talk with cardiologist at next appointment. Concerned about future vaccinations, especially another Moderna COVID. It took the next day and a half to recover from extreme fatigue caused by erratic heart beat. More

After 24 hours she reports it improved somewhat and only now involves her forearm and hand on the left. She has waited 4 days to see if it got better and it is not improving now. She is concerned it is related to the dtap injection as it started shortly after receiving it. She had pain to touch in the left arm and forearm, pain with movement of the extremity. She was able to move through a rom but painful. Temperature difference is present with the left upper extremity cooler than the right upper extremity. Strength is hindered by pain. Prescribed Prednisone 20mg qd x 5 days, Tylenol. More

As we spoke to him further, pt slumped over and started slurring his words. Then he stopped responding altogether and passed out. I heard hard breathing from him and pt became very pale. I administered an Epipen 0.3mg to patient and within 30 seconds or so, pt became responsive and woke up again. Pt immediately questioned what was going on and said he remembered nothing after feeling like he was going to pass out. Paramedics were called and by the time paramedics came, pt was fully responsive. Pt had started shivering from Epipen use. Pt was taken to hospital and I spoke to pt's father today and he states pt is back to normal and no further adverse effects were noted. More

Within 2-3 months of receiving the vaccine, the daughter had "full blown Graves"; thyroid disease; This spontaneous report was received from a Pharmacist (the patient's mother or grandmother, discrepancy) and refers to an Adult female patient (exact age unknown). The patient's medical history was not reported. The patient's concurrent conditions included Grave's disease. Concomitant therapies were not reported. On an unknown date, the patient started therapy with Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) (strength, dose, formulation, route and site of administration, lot # and expiration date were not reported) administered with a sterile diluent (MERCK STERILE DILUENT) (strength, dose, formulation, route and site of administration, lot # and expiration date were not reported) for prophylaxis. It was stated that the patient, who was the reporter's daughter, who had been diagnosed with Grave's disease (concurrent condition), had to get the with Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) vaccine when she went to college. Then, on an unknown date, reported as within 2-3 months of receiving the suspect vaccine, the daughter had "full blown Grave's". The reporter did not provide any further details on when this happened. She also asked if single measles and mumps vaccines were available, because her granddaughter (conflicting information) had thyroid disease (since unknown date), and showed signs of Graves. For this reason, she was unable to get the shot. The reporting pharmacist also mentioned that the Rubella portion is contraindicated in pregnancy and mentioned being allergic to components in Rubella. For this reason, the reporter was not able to get the shot. She said it would be beneficial if the single measles and mumps vaccines were still available, and that there were benefits to having access to the single components so that people with issues to Rubella could get vaccinated. The reporter mentioned being a registered pharmacist and would like to be contacted regarding her feedback. She was hoping the Company would reconsider the decision to discontinue the monovalent components as she could not get the vaccine because she was allergic. She asked why should MMR be given if people only need to get vaccinated against measles, the Rubella was causing the issues. At the reporting time, the outcome of the events was not reported. The causal relationship between the events and Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) was not provided. Upon internal review, the event of Grave's disease was determined to be medically significant. Lot # is being requested and will be submitted if received.; Sender's Comments: Based on the clinical information currently available for this individual case, there is no sufficient evidence to suggest a reasonable possibility for a causal relationship between M-M-R II vaccine and the adverse event of Grave๏ฟฝs disease. More information regarding if the vaccine was administered and the exact date of administration (if administered), the clinical course and relevant diagnostic evaluation is needed for further assessment. 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

Injection was done at 9:50a on Tuesday morning. within 15 minutes of her injection a very thick puffy rash along her leg beginning from injection site up towards her mid belly began. Leg stiffness, leg pain, and inability to walk due to her leg not being able to have weight on it happened immediately following her rash appearing. We placed warm compresses and gentle circular motions to the leg, gave Benadryl and a topical antihistamine to her leg. At 9:15pm that night, she spike a high fever of 104.1 that was not responsive for several hours to tylenol or ibuprofen to drop the fever. It took several hours of cold baths and rags to get the fever down. She had a blank stare in her face and didn't seem as though she was hearing us. At 2:30a her fever finally dropped to 102.6 and stayed there the remaining of the day (even with around the clock ibuprofen and tylenol in her system). She began vomiting off and on until 5pm that Wednesday night. Her rash spread and her leg remained stiff and painful to touch. By day 3 (Thursday) her fever is completely gone and despite the rash and her leg having a hard time walking from the vaccine site, she is otherwise okay. More
