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?

Parents observed an overnight change where he started self-stimming pretty heavily. Palms to ears while vocalizing and beating hands against ears, fidgeting with his ears, repetitive phrases, jaw clenching with lateral shifting, fingers flicking, escalating quickly within the first week. He was distracted by the stimming that they couldn't get his attention, he became very aware of sounds in general. He became preoccupied with lining up dominos, not anything he did before. He is reactive to fatigue, excitement and upset, started toe walking, he got more physical by ramming head into moms body and responding to deep pressure. More

I verified the counts for MenB and Men Conjug were correct (in fridge and MCIR). I notified doctor. Doctor asked me to call the health department for clarification on adverse reactions and to call. I spoke to someone at the Health Dept. She stated no harm will come from giving the MenB vaccine early. This will not count toward her future MenB dose when she is old enough to get it. She also stated patient could receive the Men Conjug anytime. No waiting period. I did report all information back to doctor and other.

Soreness in the arm; sore injection site; Soreness in the arm; Like he could not feel anything; bruised; This is a spontaneous report received from a Consumer or other non HCP from medical information team, Program ID. A 66-year-old male patient received BNT162b2 omi xbb.1.5 (COMIRNATY (2023-2024 FORMULA)), on 31Oct2023 as dose 1, single (Lot number: HG5967) at the age of 66 years intramuscular, in right arm for covid-19 immunisation; influenza vaccine inact split 4v (QUADRIVALENT INFLUENZA VACCINE), as dose number unknown, single (Lot number: 379AT), in left deltoid for immunisation. The patient's relevant medical history included: "Diabetes" (unspecified if ongoing); "Blood pressure high" (unspecified if ongoing). Concomitant medication(s) included: MOUNJARO taken for diabetes mellitus; TELMISARTAN taken for hypertension. Vaccination history included: Covid-19 vaccine (primary immunization series complete; unknown manufacturer), for covid-19 immunization. The following information was reported: PAIN IN EXTREMITY (medically significant), outcome "not recovered", described as "Soreness in the arm"; VACCINATION SITE PAIN (medically significant), outcome "unknown", described as "sore injection site"; HYPOAESTHESIA (non-serious), outcome "unknown", described as "Soreness in the arm; Like he could not feel anything"; CONTUSION (non-serious), outcome "unknown", described as "bruised". The events "soreness in the arm", "sore injection site" and "soreness in the arm; like he could not feel anything" required physician office visit. Therapeutic measures were taken as a result of pain in extremity, vaccination site pain, hypoaesthesia, contusion. Clinical course: The patient received all the doses of the COVID vaccine, like he received all different COVID vaccine and the last vaccine that he received (clarified as Pfizer COVID-19 Vaccine) had the side effect on him. He consulted his family doctor, and they cannot figure out why. The side effect that he is experiencing is soreness in the arm for over a year and half. The side effect is soreness in the arm, like he could not feel anything, and this was from the last vaccine that he received. LOT#: HG5967.

A 56-year-old male patient received BNT162b2 (COVID-19 VACCINE NOS MANUFACTURER UNKNOWN), as dose number unknown (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "vitiligo" (ongoing); "Graves' disease" (ongoing); "diabetes mellitus" (ongoing); "hospital" (ongoing). The patient's concomitant medications were not reported. Vaccination history included: COVID-19 VACCINE (DOSE NUMBER UNKNOWN; MANUFACTURER UNKNOWN), for COVID-19 immunisation. The following information was reported: COLD TYPE HAEMOLYTIC ANAEMIA (medically significant), outcome "unknown", described as "cold agglutinin hemolytic anemia (CAHA)". Clinical course: A 56-year-old male with a past medical history of vitiligo, Graves' disease, and diabetes mellitus presented to the hospital with symptoms of lethargy, loss of appetite, night sweats, and 10-lb weight loss for 1 month. The patient reported that the onset of the above-mentioned symptoms started within a week of the mRNA booster vaccine for COVID-19. The physical exam was remarkable for pallor and jaundice. Laboratory workup revealed leukocytosis (White blood cell count 24 K/uL), anemia (Hemoglobin 8.0 g/dL), thrombocytosis (platelets 554 K/uL), mild transaminitis (alanine aminotransferase 88, aspartate aminotransferase 164, alkaline phosphatase 273), and hyperbilirubinemia (total bilirubin 11.2 mg/dL, direct bilirubin 8.3 mg/dL). Haptoglobin was <7.75 mg/dL, reticulocyte count was elevated (30.59%), and lactate dehydrogenase was 1423 U/L, all suggestive of hemolysis (Table 1). Acute phase reactants were elevated (C- reactive protein 14 mg/dL, ferritin 944 ng/mL). The direct antiglobulin test was positive for complement component 3 (C3) but negative for immunoglobulin G (IgG), a serologic pattern consistent with CAHA. Flow cytometry showed a high CD4/ CD8 positive T-Cell ratio of 17.23. Computed tomography (CT) of the abdomen and pelvis revealed hepatosplenomegaly with isolated lymphadenopathy in the porta hepatis (Figure 1). Further evaluation, including lymph node biopsy, demonstrated a mixed lymphoid population with occasional large atypical lymphoid cells. Bone marrow biopsy revealed hypercellular marrow (70-80%) with trilineage hematopoiesis and approximately 10% involvement by atypical large CD20+, BCL2+, BCL6+ atypical B-cells, negative for CD10, MUM1, CD30, P53, and Cyclin D1. CMYC expression was equivocal (~30%). FISH analysis demonstrated complex chromosomal abnormalities with polysomy in a small subset (2%) of cells, below the diagnostic threshold but supportive of cytogenetic instability. Flow cytometry showed no blast proliferation or aberrant myeloid markers. B-cells comprised 2.01% of marrow cells. Liver biopsy showed infiltration by large atypical lymphoid cells, consistent with involvement by the patient's DLBCL. These histopathologic and immunophenotypic findings, along with the liver biopsy showing infiltration by large atypical lymphoid cells, collectively confirm the diagnosis of DLBCL. Broad-spectrum antibiotics were initiated for possible infection but later discontinued following negative infectious workup, including blood culture, urinalysis, and respiratory and urine cultures. The patient was started on prednisone (1 mg/kg) for hemolytic anemia. Lack of laboratory improvement with steroid therapy further supported the diagnosis of CAHA. Patient's hemoglobin dropped to 6.9 g/dl during hospitalization and required 1 unit of packed red blood cells transfusion. He was later discharged in stable condition with plans for oncology follow-up to initiate treatment for DLBCL; however, specific details regarding the appointment or the intended oncology provider were unavailable, suggesting he may have sought care elsewhere. Therapeutic measures were taken as a result of cold type haemolytic anaemia.; Sender's Comments: There is not a reasonable possibility that the reported event cold agglutinin hemolytic anemia was related to the suspect product event most likely due to patient underlying contributory factors. The impact of this report on the benefit-risk profile of the Pfizer product and on the conduct of the study is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to regulatory authorities, Ethics Committees, and Investigators, as appropriate.

My son was a healthy, normally developing child with no prior medical issues, seizures, or neurological concerns. He was born full-term without complications, and reached all developmental milestones early ? standing at 7 months, walking at 10 months, and talking before his first birthday. He had never experienced any high fever, infection, or unusual symptoms. On 02/11/2025, he received routine childhood vaccinations, including DTaP, Polio, Hep B, HIB, administered by intramuscular injection into his left/right thigh. Within a few hours of receiving the vaccine, while sleeping, he let out a loud, sudden scream and was found by his mother in an active seizure ? involving body shaking and jerking. He had no fever at the time. This was his first-ever seizure. Following this event, he began experiencing recurrent myoclonic seizures, primarily during sleep but occasionally while awake. These included sudden jerks, dropping objects, and body twitches. His pediatrician referred him to a pediatric neurologist. An EEG confirmed abnormal electrical activity consistent with myoclonic epilepsy. An MRI of the brain revealed multifocal white matter abnormalities with gliosis, indicating brain scarring from a prior injury. He was prescribed Levetiracetam (Keppra) for seizure control, which he continues to take daily. Despite treatment, seizures have persisted. There is growing concern from the family that this was a vaccine-induced neurological injury, as the onset of symptoms was immediate and no other cause (genetic, metabolic, infectious, or traumatic) has been identified. His development, although initially advanced, has shown some slowing since the incident. More
