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

Co-suspect products included Hepatitis B vaccine for prophylaxis. Concomitant products included Hepatitis b vaccine. On 06-MAR-2015, the patient received the 3rd dose of Engerix B. On 16-JAN-2015, the patient received the 2nd dose of Hepatitis B vaccine. On 16-JAN-2015, not applicable after receiving Engerix B and an unknown time after receiving Hepatitis B vaccine, the patient experienced drug dose administration interval too long (Verbatim: 2nd dose administered on 16 Jan 2015). On 06-MAR-2015, the patient experienced drug dose administration interval too short (Verbatim: third dose was given as an early dose). The outcome of the drug dose administration interval too short and drug dose administration interval too long were not applicable. This report is made by GSK without prejudice and does not imply any admission or liability for the incident or its consequences. Additional Information: GSK Receipt Date: 09-JUN-2025 Physician explained that a 10 year old patient received by accident an expired forth dose of a Hepatitis B vaccine (lot number W025817, expiration date 21st May 2025, brand name not provided by the caller, but they mentioned that it was non-GSK product) on 2nd June 2025 since they noticed that their third dose was given as an early dose. First dose of Hepatitis B was given on 5th November 2014, second dose on 16th January 2015 and third dose on 6th March 2015 which led to Drug dose administration interval too short. Physician did not know what the brand name or lot number for any of the 3 prior doses was. Adverse Event report sent as a preventive measure as a potential early third dose of Engerix-B, and potential interchangeability, since the fourth dose was not a GlaxoSmithKline vaccine. Caller decided to end the call when they noticed that the fourth dose was not from GlaxoSmithKline so Medical Information did not have time to ask for consent to follow up with Safety Team. The patient received 2nd dose of Hepatitis B later than the recommended schedule, which led to lengthening of vaccination schedule. More

The patient's medical history, concurrent conditions and concomitant therapies were not reported. He reported that he thought that he received his MMR vaccines from work in 1998 but did not have work vaccination records so he got vaccinated in order to obtain a job. He reported that he has had multiple shots and never had a reaction to a shot before. On 13-Mar-2025, the patient was vaccinated with Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) (lot #Y004116 and expiration date reported as 12-Feb-2026) (dose, route of administration and vaccination site were not reported) administered for prophylaxis. The vaccine was reconstituted with sterile diluent, solution for injection. The patient reported that he wanted to know the chain of custody for this vaccine "to make sure there was no foul play here." Due to this statement, this was being reported as a CDT case. Answers to CDT questions were unknown as all consumer had was a sticker which showed the lot, expiry date and serial number for the product. The patient also reported that he wanted to make sure the integrity of the vaccine was solid and reported "that is your companies name". He reported that he was not here to "ruin anybody" and that he just wanted to live his life and be healthy. On an unspecified date in March 2025 (1-2 weeks after vaccination), the patient reported a rash on the back of his head as well as both hands (rash). He reported his scalp was itchy and red (pruritus; erythema). He got what he reported to be pimples that hurt and when they pop blood and sometimes clear fluid oozes out (acne). He reported burning in his rectal and penile area and an occasional burning sensation in the pelvic area (anorectal discomfort; penile burning sensation; pelvic discomfort). He went to the clinic 3 separate times for these symptoms. He reported that they originally treated him with hydrocortisone cream and then an antifungal. He reported that he drove to the hospital for treatment, and was not admitted and they sent him home with ketoconazole and an antifungal shampoo which has not improved his symptoms. He reported being hesitant to touch animals unless his hands were washed because he did not want to make them sick if he was contagious (fear of disease). The patient was also experiencing longer than normal recovery periods (exercise tolerance decreased). The outcome of the reported adverse events was reported as not recovered. The causal relationship between the reported adverse events and Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) was not reported. More

Started as slight shaky and weak feeling throughout the body, progressed to full body aches and fever with chills as well, as if body could not decide if it was hot or cold. By 11:00am symptoms were in full effect and I experienced labored breathing with fever reaching 100 degrees Fahrenheit. Before noon, joint pain in knees, arms, legs, back, and feet started, putting me in more pain and discomfort. I was struggling to focus on work and had trouble writing and typing on computer due to extreme weakness. Headaches made it difficult to concentrate on work and leg pain made it difficult to sit in chair for too long. Symptoms lessened by evening, was still experiencing leg pain and whole body aches with headaches. Took Aleve to help lessen aches, leg pain worsened during the night when I would lay down to sleep. Pain became unbearable during this time, making sleep impossible. It has now been over 48 hours since symptoms started on 6/16 and only slight leg and knee pains persist today, 6/18. Fever and chills are gone as well as whole body weakness and aches. More
