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

At the time of the report, MULTIPLE SCLEROSIS RELAPSE (Moderna Vaccine activated her MS/low energy) had not resolved. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Magnetic resonance imaging: Stable and did not show any active lesions or anything. Concomitant medication was not provided. It was reported that the patient was 68-69 years old at onset and reported her weight as too much and stated that she was completely mobile. It was reported that the patient had MS for 30 years and had received original covid vaccine in 2020. She had received 6 booster doses from Pfizer and reported that she had not experienced any problems and was doing well. She also reported that she had experienced a flu shot type response with the Pfizer covid vaccines. She had received her 7th booster dose from Moderna, and the Moderna vaccine had activated her MS leading to a robust response for which she had to go on corticosteroids due to MS complications. The complications included low energy and difficulty getting out of bed. Her neurologist had advised her against getting another covid vaccine which had been 2 years ago. She was ambulant but did not want to risk activating her MS and she was seeking advice on whether or not to get the new vaccine. She was worried about having a robust response to the COVID vaccine and did not want to aggravate her MS. It was also reported that she was on an immunosuppressant at the time she had the Moderna vaccine but was modulated. She clarified that she had a sore arm and down with energy a little bit for a day or so after receiving the Pfizer Covid-19 Vaccines which she was described as not a big deal and did not consider it as a negative outcome. She had stated that she did not want a recurrence of severe reaction she experienced with moderna vaccine, where she had struggled to get out of bed for a couple of weeks. The response to the Pfizer vaccine was described as level 1-2 compared to level 9-10 she had with Moderna. She noted that the difference was significant. It was way less than the shingles vaccines. It was not even on her radar. The patient also stated that the Moderna Covid-19 Vaccine had kicked her butt.

The occurrence of additional non-serious events is detailed below. Co-suspect product included non-company product COVID-19 vaccine mRNA for an unknown indication. The patient's past medical history included Atrial fibrillation (it was up to 41% of the time. Did not had a fibrillation now for about a year and a half), Nosebleed (ENT consultation for a nosebleed and was going to go on anticoagulants (Eliquis)), Cardiac pacemaker insertion, Cardiac ablation and Cardiac operation NOS (3 cardiac procedures). Previously administered products included for Product used for unknown indication: Shingrix on 02-Feb-2022 and Pfizer COVID-19 vaccine (late of 2023) in 2023. Past adverse reactions to the above products included No adverse effect with Pfizer COVID-19 vaccine and Shingrix. Family history included Rheumatic heart disease (Mother-in-law) since an unknown date, Atrial fibrillation (Mother-in-law) since an unknown date, Clot blood (formed a clot/ went to her brain and killed mother-in-law) since an unknown date and Malignant melanoma stage III (daughter; was on the buttock/ serious melanoma, a stage 3). Concurrent medical conditions included Hypertension, Supraventricular tachycardia, Sick sinus syndrome (was going to do a cardiac ablation, but then he developed a very slow heart rate, 28 per minute due to what was called sick sinus syndrome), Pre-diabetes and Telangiectasia (took care of that, so he was able to go on the anticoagulant). Concomitant products included Apixaban (Eliquis) for an unknown indication. On 24-Jun-2024, the patient received dose of mRNA-1273.815 (SPIKEVAX 2023-2024) (Intramuscular use) 1 dosage form. On 27-Sep-2024, the patient received dose of COVID-19 vaccine mRNA (unknown route) 1 dosage form. In 2025, the patient experienced MALIGNANT MELANOMA STAGE 0 (About 3 or 4 months ago had a melanoma surgery due to a discovery of a mole at the tip of nose/ melanoma in situ, that was called stage 0) (seriousness criterion medically significant). On an unknown date, the patient experienced SQUAMOUS CELL CARCINOMA (squamous cell cancer) (seriousness criterion medically significant), BASAL CELL CARCINOMA (basal cell cancers) (seriousness criterion medically significant) and EYE DISORDER (some abnormalities in eyes). The patient was treated with Surgery (Melanoma surgery) for Malignant melanoma stage 0; Surgery (Melanoma surgery for squamous cell cancer) for Squamous cell carcinoma and Surgery (Melanoma surgery for basal cell cancers) for Basal cell carcinoma. At the time of the report, MALIGNANT MELANOMA STAGE 0 (About 3 or 4 months ago had a melanoma surgery due to a discovery of a mole at the tip of nose/ melanoma in situ, that was called stage 0), SQUAMOUS CELL CARCINOMA (squamous cell cancer), BASAL CELL CARCINOMA (basal cell cancers) and EYE DISORDER (some abnormalities in eyes) outcome was unknown. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Heart rate: 255 heart beats per minute and 28 heart beats per minute. For mRNA-1273.815 (SPIKEVAX 2023-2024) (Intramuscular use), the reporter considered EYE DISORDER (some abnormalities in eyes) to be not related. No further causality assessments were provided for MALIGNANT MELANOMA STAGE 0 (About 3 or 4 months ago had a melanoma surgery due to a discovery of a mole at the tip of nose/ melanoma in situ, that was called stage 0), SQUAMOUS CELL CARCINOMA (squamous cell cancer) and BASAL CELL CARCINOMA (basal cell cancers). The patient had 3 vaccinations with Shingles vaccines- Shingrix on 02-Feb-2022 and 2 other shingles shots, which were also given 7 to 8 years ago but were not as effective as Shingrix vaccine. Patient had undergone melanoma surgery for basal cell cancers and a squamous cell cancer which was performed since the patient has had his last dose. The patient had some abnormalities in his eyes and would be seeing the ENT physician in about 2 weeks for an annual checkup. The reporter stated that when the patient was getting to be 85 years old, patient would just start falling apart. About 3 or 4 months ago, patient had undergone a melanoma surgery due to the discovery of a mole at the tip of nose which patient found an unusual place to have melanoma as well as an obvious site, so it was discovered early. The reporter mentioned it as melanoma in situ, stage 0. That meant it was almost pre-cancerous. The patient wanted to find mNEXSPIKE in the country. The patient had received a total of 6 COVID-19 shots. The patient had not received any COVID-19 shots in the past 6 months but probably a year since his last COVID-19 vaccine. He had the COVID-19 vaccines when they had first started to make it available which was 3-4 months since the first release making sure that people were not having horrendous reactions. The patient thought that it was back in 2021. He had the first series with Pfizer, and the third shot was Moderna and then every other one as one Moderna dose and one Pfizer dose afterwards. The patient did not experience any additional symptoms/events. No treatment drug was reported.; Reporter's Comments: Co-suspect non-company product COVID-19 vaccine is a confounder for the events. Due to lack of biological plausibility, the causality of the events malignant melanoma stage 0, squamous cell carcinoma and basal cell carcinoma were assessed as not related to the vaccine. The benefit -risk relationship of product is not affected by this report. More

The events "she has some kind of unknown bleeding disorder", "nose bleeds" and "nose bleeds/bleeding disorder" required physician office visit. Therapeutic measures were taken as a result of haemorrhagic disorder, epistaxis, condition aggravated. Clinical Course: She has some kind of unknown bleeding disorder. She passed all tests for bleeding disorder and is not on blood thinner but they are calling it unknown bleeding disorder. Does it have same action as taking Aspirin or Advil. Those are medications that seem to bring on bloody noses for her. She had no problem with previous vaccines. Patient has a question about the most recent Pfizer Covid shot. he read something about medical conditions such as bleeding disorder or blood thinners. Her last Pfizer Covid 19 vaccine was in Nov2024. Reported "I have a preexisting condition, before receiving the COVID vaccines, called Waldenstrom macroglobulinemia, a rare lymphoma, but not on treatment because I don't have any symptoms and on a watch and wait. I also have a bleeding disorder or reaction to aspirin and Advil or NSAIDs (also preexisting condition to COVID vaccines) since about 20-25 plus years ago, that if i take more than a couple of them, I would have nose bleeds. I am not on a blood thinner. The last bad one was in Jan or Feb2025, every couple of weeks but one day, it was like a terrible hemorrhaging nose bleed that lasted 24 hours. It started with blood just coming down to the floor and I had a towel and holding my nostril for hours and bought nose clips and finally got it under control. Eventually it stopped. I went to a throat doctor to cauterize it. It happened again after the cauterization but eventually it stopped. I don't have that high of a blood pressure but on high blood pressure medication and perhaps it is related to that. My platelets are fine and I clot well if I have an injury or if I get a scratch or cut. My doctor says I have a blood disorder of unknown cause. My immune system is not that good because of this Waldenstroms disease and since my IgMs go up with my disease, we have to watch that. When I get a vaccine, the IgM number really goes up and then it goes down within months. This is what happened after the last Pfizer Covid 19 vaccine in Nov2024, my IgM numbers went up after the vaccine and then the IgM numbers went down over time. " The information on the batch/lot number for BNT162b2 omicron (kp.2) will be requested and submitted if and when received. More
