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

The patient's past medical history included Sinus infection. Previously administered products included for COVID-19 prophylaxis: Spikevax NOS (over the past 4-5 years). Past adverse reactions to the above products included No adverse effect with Spikevax NOS. Concurrent medical conditions included Diabetes. Concomitant products included Methylprednisolone (Medrol) for Sinus infection. On an unknown date, the patient received dose of mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (Intramuscular use) 1 dosage form. In 2023, the patient experienced URTICARIA (hives/previously developing hives from a Moderna COVID booster). The patient was treated with Fexofenadine hydrochloride (Allegra) in 2023 for Hives, at a dose of 6 weeks. In 2023, URTICARIA (hives/previously developing hives from a Moderna COVID booster) had resolved. Relevant Medical History (vaccines within the past 4 weeks, medical conditions) were reported as none. The patient had no medical history, concomitant disease or risk factors. The patient had several shots before without any adverse reactions. Patient was on oral steroids called Medrol Pack while he had his last Moderna COVID-19 vaccine in 2023. A couple of years ago, a patient had the Moderna booster, stating he had several Moderna COVID shots over the past 4-5 years, starting with the original ones that came out in 2020 or 2021. And one of the boosters he received in July of 2023, a couple of weeks after he got that booster, he developed hives. He received multiple vaccines previously without developing hives. When he had the shot, he was on steroids. So, when the patient came off, when he came for a sinus infection, so when he came off the steroids, 2 weeks after that, the hives started. So, it's essentially the same as 2 weeks after the vaccine. The hives stopped. He had no other side effects but just the itching and the hives. Patient switched to Pfizer COVID-19 boosters for the past 2 years and had no reaction aside from the sore arm. He had no systemic reaction from the Pfizer COVID-19 vaccine. It did last like 6 weeks, and it was annoying. Patient had probably about 5 or 6 Moderna COVID-19 vaccines and probably about maybe 3 Pfizer COVID-19 boosters. There were no lab data/results available. It was unknown if the patient experienced any additional symptoms/events. Reporter causality was not reported. Patient took Allegra for 6 weeks, an antihistamine before the hives stopped.

In 2025, the patient experienced MOBILITY DECREASED (could not get off the floor or get into bed or anything). On 13-Aug-2025, the patient experienced PERICARDIAL EFFUSION (emergency pericardio window to drain the fluid around her heart) (seriousness criteria hospitalization and medically significant). On 17-Sep-2025, the patient experienced MALAISE (starting not to feel well/ feeling woozy) and DIZZINESS (starting not to feel well/ feeling woozy). On an unknown date, the patient experienced FOOT DEFORMITY (Flinstone feet). The patient was hospitalized from sometime in August 2025 to sometime in August 2025 due to PERICARDIAL EFFUSION. The patient was treated with Surgery (emergency pericardio window to drain the fluid around heart) for Pericardial effusion. At the time of the report, PERICARDIAL EFFUSION (emergency pericardio window to drain the fluid around her heart) had not resolved and PNEUMONIA (Pneumonia/musculoskeletal chest pain), MALAISE (starting not to feel well/ feeling woozy), FOOT DEFORMITY (Flinstone feet), BREATH SOUNDS ABNORMAL (The loud sound on her chest), MOBILITY DECREASED (could not get off the floor or get into bed or anything) and DIZZINESS (starting not to feel well/ feeling woozy) outcome was unknown. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In 2025, Computerised tomogram: did not saw any break or any problem. In 2025, Imaging procedure: undergone numerous imaging procedures to determine if had a broken rib but the imaging resulted to no broken rib to be found. In 2025, Magnetic resonance imaging: did not saw any break or any problem. On an unknown date, Biopsy: During the biopsy, the doctors found out that the patient had pneumonia. Concomitant medication included antibiotic treatment. The patient went through an emergency pericardio window to drain the fluid around her heart and was in the ICU for 4 days. The fluid around her heart was building up again despite the draining. The procedure emergency pericardio window did not end the problem. The patient never had a problem with heart in her whole life. The patient was a breast cancer survivor and undergone another surgery, biopsy, a month later looking for lung cancer. The patient was currently on antibiotic treatment and had 2 more days left of the regimen, but her coughing had not stopped. On 17-Mar-2025, the patient heard a loud sound on her chest which felt like a broken rib and since then she was not feeling well. She had not been normal since the 17-Mar-2025. The loud sound on her chest was like she was going through chiropractic procedures but was a bit louder. The patient could not get off the floor or get into bed or anything for it seemed like 4 months really bad like she had to beg the doctor for a muscle relaxer just to sleep. As per the patient it might be the pneumonia that was causing a tremendous amount of pain. The patient had flintstone feet which shared to be a very big sign. The patient had to look every single day to see if ankles and feet look swollen because it could happen again. The patient's cardiologist was currently doing all kinds of massive testing like nuclear things. The patient experienced musculoskeletal chest pain (rib cage pain that goes back and forth on the right and left side), chest discomfort due to coughing dyspnea (difficult/labored breathing), dyspnea at rest, dyspnea exertional and lethargy. There was no history of COVID-19 infection nor any history of myocarditis/pericarditis. It was unknown if the patient experienced any additional symptoms/events. No treatment medication was reported. Most recent FOLLOW-UP information incorporated above includes: On 17-Sep-2025: Live follow-up received contains non-significant information (reference number was added).; Reporter's Comments: Causality for Pneumonia was assessed as not related, due to lack of biological plausibility. Causality for Pericardial effusion and Breath sounds abnormal was assessed as not related, due to long latency. The benefit-risk relationship of product is not affected by this report. More

Covid; severe rash and hives/quickly developed into welts/The welts all over his body were recurring; This spontaneous case was reported by a consumer and describes the occurrence of COVID-19 (Covid) and URTICARIA (severe rash and hives/quickly developed into welts/The welts all over his body were recurring) in an adult male patient who received mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (batch no. 8080473) for COVID-19 prophylaxis. Co-suspect product included non-company product Influenza vaccine (Fluzone) for an unknown indication. Previously administered products included for COVID-19 prophylaxis: Spikevax NOS (he did not have any problems in 2023). Past adverse reactions to the above products included No adverse effect with Spikevax NOS. Concurrent medical conditions included Hypertrophic cardiomyopathy. On 12-Sep-2024, the patient received dose of mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (Intramuscular use) .5 milliliter and dose of Influenza vaccine (Fluzone) (unknown route) 1 dosage form. In 2024, the patient experienced COVID-19 (Covid) and URTICARIA (severe rash and hives/quickly developed into welts/The welts all over his body were recurring). The patient was treated with Diphenhydramine hydrochloride (Benadryl) in 2024 at an unspecified dose and frequency; Levocetirizine dihydrochloride (Xyzal) in 2024 at an unspecified dose and frequency and Famotidine (Pepcid) in 2024 at an unspecified dose and frequency. At the time of the report, COVID-19 (Covid) outcome was unknown and URTICARIA (severe rash and hives/quickly developed into welts/The welts all over his body were recurring) had resolved. He received the Spikevax and flu vaccine on the same day last year and had a 4 1/2-month-long reaction, severe rash and hives. He had taken it every year (the Spikevax vaccine) it had been available, and this was his first adverse reaction. He had a serious heart condition, hypertrophic cardiomyopathy, that puts him at risk (it was genetic). He was on some really powerful drugs that precluded him from taking Paxlovid, so his health professionals wanted him to take Spikevax. It was one of the worst reactions they had ever seen. His symptoms started with rashes at various locations on his body (eyes, lips) and quickly developed into welts. The welts all over his body were recurring. The welts were 2 inches in diameter all over his body, on his eyes and routinely on his lips. He phased off eventually after 4 or 5 months and kept trying alternate and, finally, the reaction subsided in his body, and he was free of the issues. He was symptom-free. The patient did not want to go through COVID again, he had been through it and could not take Paxlovid as he did not want to risk his chance of dying. It was unknown if the patient experienced any additional symptoms/events. The immediate treatment was Benadryl. It made him draggy, sleepy and feel yucky. He was living on Benadryl until he started on Xyzal. He actually started with a daily antihistamine, and it provided him with some relief, but he would still sporadically develop hives. Then he tried Pepcid in addition to that. The cocktail of Xyzal and Pepcid allowed him to stop Benadryl. The overnight antihistamine, Xyzal and Pepcid (an antacid which goes to one of the receptors on the histamine). Reporter causality was not provided.
