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

πŸ’‘ 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 "πŸ“₯ Export CSV" to download filtered data (max 10,000 records)

πŸ’‘ Frequently Asked Questions (FAQ)

What is this site?

πŸ₯ 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:

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

Limitations:

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

Where can I learn more?

He came in because he thought the rash was bedbugs but he had shingles in 2 contiguous dermatomes - T9ish on the right. He then came back to see me again today, 2/12/2025, because he now has postherpetic neuralgia. I understand that you can't get shingles from the vaccine because there's no live virus in the vaccine,,but he has a history of chickenpox. Could the vaccine or the resulting immune response have caused his VZV to reactivate and cause the disease? More

Prior to that vaccine series, my platelet counts were always in normal lab range. After the vaccine series, my platelet count rose continually and were outside the normal lab ranges. I went to a hematologist in March 2023 and after blood work, genetic testing and a bone marrow biopsy, I was diagnosed with essential thrombocytosis (ET) with a CALR mutation on exon 9 in September 2023. My correlation is the COVID vaccine series disrupted my genetics and caused the ET. I had no history of high platelets prior to the COVID vaccine series. More

He assisted her to the kitchen table and then to the living room chair in the rolling chair because she was unable to walk on her own. He contacted a nurse friend of theirs and she was concerned that she may have had a stroke and recommended she be taken to the ER. He contacted an ambulance to take her to ER Hospital. They did multiple test that were all normal. She was running fever and her right arm was red so she was admitted for observation for 48 hours. She was discharged after PT and OT approved her to go home and told to contact PCP for follow up. She is scheduled to be seen on 2/17/25. More

Patient had unusual pain in her right arm following the HPV vaccine along with decreased mobility. This lasted for approximately 4-6 weeks. I thought it was just vaccine soreness and as we were getting ready to follow up to check on this, the pain and mobility issues began to subside so we did not schedule. She did continue to complain of a muscle spasm in her neck with discomfort. We mentioned this at her 2023 well child visit, but the doctor said it was probably just from her looking down at her phone or something. Late fall (2023), we noticed drooping in her shoulder. Unaware of what it was from or what was wrong, we started off with a chiropractor (2 visits). This was of zero benefit so we started OMT in January 2024. After a few sessions, the doctor determined it was in fact her trap muscle vs an alignment issue. We were referred to a local orthopedic doctor (Dr) who then referred us for the first of 2 EMGs. This concluded her spinal accessory nerve was not functioning. We attempted physical therapy with nerve stimulation, but nothing was helping. At this point, we were starting into summer of 2024. An MRI was ordered to confirm no tumors or masses compressing the nerve, there was not. We were then referred to an orthopedic doctor specializing in brachial plexus (Dr). We had a second EMG completed. He sent us to hospital for a neurography to check for hour glass constrictions in her nerve. The radiologist concluded it had most likely been to long to see the constrictions. Dr felt confident her diagnosis was Parsonage Turner Syndrome due to her HPV vaccine (autoimmune response), but we needed to do our due diligence and rule everything out. She had a group of vessels noted on the neurography so we were referred to a neurosurgeon and had an angiogram completed to see if that was an issue. This was determined to be nothing and not contributory at all. At this point, it was November of 2024. Dr determined she would not recover at all due to the extensive and severe muscle deterioration in her trapezius and sternocleidomastoid muscles. It was causing pronounced muscle weakness and scapular winging which in turn caused forward shoulder rotation. She was experiencing a lot of stiffness, pain, and discomfort. Since her scapula had very little support due to trap muscle deterioration, she had to have a triple muscle transfer on 1/13/25. We were informed she would never recover and this was strictly a surgery to help deal with the damage. She will have lifelong damage and complications. More

The day after the second vaccination, I woke up with extreme sensitivity to light in my left eye and to sound in my left ear. It was extremely painful. The pain was about the size of a CD on the left side of my head. It felt as though my skull was swelling and might explode. I was also off balance and had a tremor in my left hand. This lasted for weeks and then gradually became less. The light and sound sensitivity flares up from time to time - maybe once a month or so. The balance problems and tremor remain. More

I have video of the οΏ½balcony visits' allowed during Covid before the vaccine rollout, and you can see, although elderly, she was cognizant and present in mind.
