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

Where can I learn more?

Maladministration of pediatric dose on adult patient; Adult use of a child product; This non-serious case was reported by a other health professional via call center representative and described the occurrence of accidental underdose in a adult patient who received HAV (Havrix pediatric) for prophylaxis. On an unknown date, the patient received Havrix pediatric. On an unknown date, an unknown time after receiving Havrix pediatric, the patient experienced accidental underdose (Verbatim: Maladministration of pediatric dose on adult patient) and adult use of a child product (Verbatim: Adult use of a child product). The outcome of the accidental underdose and adult use of a child product 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: 25-APR-2025 The vaccine service center transferred a pharmacy technician who called to ask about the dosage/schedule for ten adult patients who were maladministered pediatric doses of the Havrix vaccine. The reporter stated that the adult patients had received pediatric doses, which led to the adult use of a child product and accidental underdose. The reporter asked if there was any guidance/advice on this situation, but no vaccination date, vaccine details, or patient demographic details were provided by the pharmacy technician.

At that time, my heart stopped, and I required defibrillation via an automated external defibrillator (AED). I regained consciousness en route to the hospital. Subsequent extensive testing has not identified a cause for this event, and I have since had an internal defibrillator implanted. I received the Moderna COVID-19 vaccine prior to this event and am concerned about a potential correlation between the vaccination and my cardiac arrest, particularly given discussions regarding potential cardiac issues in men my age following mRNA vaccines. I urge the FDA to investigate potential links between COVID-19 vaccines and unexplained cardiac events. I am available to provide further details about my experience if needed. Thank you for your time and attention to this important matter. More

After my second injection my shortness of breath really increased, had to be put on home oxygen, I also developed tachycardia. I had made 3 trips to the ER Because I was so short of breath. At approximately 6/25/21 I had developed a 100 degree fever with pain in my lower back rt side. I also felt bubbling and rubbing in my lower lungs. It was so painful that I could only sleep on my side. I felt that something was really wrong. I messaged my Dr twice. All she did was order a plain Xray of my chest in her office, it was normal. She didn't do any more, I was disappointed and worried. By 11 pm 7/1/21 I was so sick, coughing alot too, I drove myself to the ER. More

On an unknown date, the patient received Priorix. On an unknown date, an unknown time after receiving Priorix, the patient experienced wrong solution used in drug reconstitution (Verbatim: seems that they may use the Shingrix diluent for the Priorix lyoph powder) and inappropriate dose of vaccine administered (Verbatim: vaccines where given without the diluent). The outcome of the wrong solution used in drug reconstitution and inappropriate dose of vaccine administered 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: 24-APR-2025 Other HCP reported that they had 2 situation which the diluent was not use to diluent the injection. Reporter stated that they had in the inventory 2 Priorix diluents left alone, so that's why they assume the Priorix vaccines were given without the diluent. Also, indicated that they also had the Shingrix vaccine, so due to this, it seems that they may use the Shingrix diluent for the Priorix lyoph. powder, HCP did not confirmed this. Priorix reconstituted with diluent of Shingrix instead of the supplied liquid conjugate, which led to wrong solution used in drug reconstitution and inappropriate dose of vaccine administered. More

The occurrence of additional non-serious events is detailed below. LITERATURE REFERENCE: The patient's past medical history included Lung infection (recurrent sinopulmonary infections as a child), Sinus infection (recurrent sinopulmonary infections as a child), Community acquired pneumonia (several hospitalizations), Seizure (several hospitalizations), Asthma (several hospitalizations for moderate-persistent asthma), Obstructive sleep apnea (several hospitalizations for mild obstructive sleep apnea) and Attention deficit hyperactivity disorder (several hospitalizations). Family history included Myelitis transverse (mother died at age 64 from complications related to transverse myelitis). Concurrent medical conditions included Macrocytic anemia (long-standing history of a mild underproduction macrocytic anemia). On an unknown date, the patient received dose of SPIKEVAX NOS (SPIKEVAX NOS) (unknown route) 1 dosage form. On an unknown date, after starting SPIKEVAX NOS (SPIKEVAX NOS), the patient experienced HYPOGAMMAGLOBULINAEMIA (hypogammaglobulinemia) (seriousness criterion medically significant), SIDEROBLASTIC ANAEMIA (LIG1 deficiency that presented with macrocytic sideroblastic anemia), GENE MUTATION (LIG1 deficiency that presented with macrocytic sideroblastic anemia) and COVID-19 (Patient developed SARS-CoV-2 infection 1 year after completing the primary series). The patient was treated with Immunoglobulin human normal (Immunoglobulin) at an unspecified dose and frequency. At the time of the report, HYPOGAMMAGLOBULINAEMIA (hypogammaglobulinemia), SIDEROBLASTIC ANAEMIA (LIG1 deficiency that presented with macrocytic sideroblastic anemia) and GENE MUTATION (LIG1 deficiency that presented with macrocytic sideroblastic anemia) outcome was unknown and COVID-19 (Patient developed SARS-CoV-2 infection 1 year after completing the primary series) had resolved. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Aspiration bone marrow: normocellular marrow for age with a relative erythroid hyperplasia (myeloid to erythroid ratio of 0.6:1) associated with dyserythropoiesis in a subset of erythroids, including nuclear irregularities, binucleation, and budding, as well as megaloblastic maturation. Iron stain revealed >?15% ring sideroblasts.. On an unknown date, Biopsy bone marrow: normocellular marrow for age with a relative erythroid hyperplasia (myeloid to erythroid ratio of 0.6:1) associated with dyserythropoiesis in a subset of erythroids, including nuclear irregularities, binucleation, and budding, as well as megaloblastic maturation. Iron stain revealed >?15% ring sideroblasts.. On an unknown date, Blood folate: normal. On an unknown date, Electrophoresis: To confirm that the c.776+5G>T allele impacts splicing, reverse transcriptase polymerase chain reaction (RT-PCR) primers (LIG1_F: CAGGAGGAGGAAGAGCAGAC; LIG1_R: CAGGCATCTTCCACGGGAT) spanning the splice junction between exon 9 and 10 was performed. Agarose gel electrophoresis of RT-PCR amplicons showed a larger splicing product. Next-generation sequencing of this amplicon identified a 16-base pair insertion in transcripts derived from the c.776+5G>T allele (c.776ins16) predicted to result in a frameshift and termination present in 36% of the reads. It was unclear if this decreased transcript abundance was secondary to reduced efficiency of splicing at the normal splice donor site or nonsense-mediated decay of the aberrantly spliced mRNA. Whatever the mechanism, this finding supports\ed the notion that the c.776+5G>T allele was a genetic hypomorph.. On an unknown date, Flow cytometry: Flow cytometry on the marrow identified no abnormal myeloid, B, or T cell populations, and routine karyotype was 46, XX.. On an unknown date, Gene sequencing: (Negative) Clinical ALAS2 sequencing and In whole exome sequencing patient was found to have compound heterozygous LIG1 mutations (c.1922G>T, p.R641L and c.776+5G>T, NM_000234.3) that were confirmed to be in trans by PacBio long-range genomic sequencing.. On an unknown date, Haemoglobin: 11.6 gram per litre. On an unknown date, Immunophenotyping: Immunophenotyping showed mildly reduced CD19+ B cells, normal numbers of CD27+ memory B cells, and reduced immunoglobulin (Ig) class-switching with low IgM/IgD memory cells and virtual absence of IgA+ and IgG+ class switched memory B cells.. On an unknown date, Mean cell volume: 125 fL. On an unknown date, Natural killer cell count: Normal. On an unknown date, T-lymphocyte count: T cell was Normal. On an unknown date, Vitamin B12: Normal. For SPIKEVAX NOS (SPIKEVAX NOS) (Unknown), the reporter did not provide any causality assessments. Concomitant medications were not reported. The patient's full brother and 2 maternal half-sisters are healthy. Vaccination titers were protective for only 3 of 23 pneumococcal serotypes. T and NK cell numbers were normal, and response to mitogen stimulation with phytohemagglutinin and CD3 was normal. The patient was started on replacement immunoglobulin. She developed SARS-CoV-2 infection 1?year after completing the primary series of the mRNA-1273 vaccine and was successfully managed with antiviral therapy as an outpatient. This was first reported case of LIG1 deficiency diagnosed in an adult patient. Patient had mild clinical phenotypes. Patient harbored one missense variant that results in reduced LIG1 activity and a splice site variant, which may allow for some residual wild-type enzyme activity, accounting for the relatively mild clinical presentations. This report broadens the clinical spectrum of LIG1 deficiency and highlights the increasing awareness that inborn errors of immunity may manifest with a wide range of immunological features and varying degrees of disease severity. As the immune deficiency can be subtle, LIG1 deficiency should be considered in the differential diagnosis of patients presenting to hematologists with macrocytic sideroblastic anemia. Patient did not show evidence of excessive somatic heteroplasmic mitochondrial DNA variants, which argues against a major impact of LIG1 deficiency on mitochondrial DNA replication and repair.; Reporter's Comments: Long-standing history of macrocytic anemia remains as a confounder for sideroblastic anaemia. The benefit-risk relationship of product is not affected by this report. More
