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.

  • 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

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

Concurrent medical conditions included low back pain, coronary artery disease (status post bypass grafting), coronary artery bypass graft, aortic valve replacement, sick sinus syndrome (status post pacemaker placement), cardiac pacemaker insertion, hypertension, paroxysmal atrial fibrillation, cardiac failure (with preserved ejection fraction), thoracic aortic aneurysm, chronic anemia, prostate cancer stage iv (status post retro pelvic prostatectomy), prostatectomy, radiation therapy, bone metastases (extensive), crackles lung, jugular vein distension, pedal edema, asterixis, ecchymosis (in the left upper extremity), pulmonary edema and urinary retention. Additional patient notes included Patient had not recently started any other new medications or herbal supplements. Concomitant products included abiraterone acetate, prednisone, leuprorelin acetate (Leuprolide Acetate), ELASOMERAN (MODERNA COVID-19 VACCINE), INFLUENZA VACCINE and rituximab. On an unknown date, the patient received Arexvy. On an unknown date, less than a day after receiving Arexvy, the patient experienced thrombotic microangiopathy (Verbatim: respiratory syncytial virus vaccine induced thrombotic microangiopathy/vaccine-induced thrombotic microangiopathy/microangiopathic hemolytic anemia) (serious criteria hospitalization, GSK medically significant and clinically significant/intervention required), metabolic encephalopathy (Verbatim: metabolic encephalopathy) (serious criteria hospitalization, GSK medically significant and clinically significant/intervention required), anuric renal failure (Verbatim: anuric renal failure) (serious criteria hospitalization, GSK medically significant and clinically significant/intervention required), multi-organ failure (Verbatim: multi-organ failure) (serious criteria hospitalization, GSK medically significant and clinically significant/intervention required) and acute hypoxic respiratory failure (Verbatim: acute hypoxic respiratory failure) (serious criteria hospitalization, GSK medically significant and clinically significant/intervention required). The patient was treated with prednisone. The outcome of the thrombotic microangiopathy and anuric renal failure were resolved and the outcome of the metabolic encephalopathy, multi-organ failure and acute hypoxic respiratory failure were resolving. The reporter considered the thrombotic microangiopathy, metabolic encephalopathy, anuric renal failure, multi-organ failure and acute hypoxic respiratory failure to be related to Arexvy. The company considered the thrombotic microangiopathy, metabolic encephalopathy, anuric renal failure, multi-organ failure and acute hypoxic respiratory failure to be related to Arexvy. Additional Information: GSK Receipt Date 21-AUG-2025. Author reported a patient presented to hospital with severe low back pain and urinary retention. Patient received the new adjuvant RSV vaccine, known as Arexvy, the day prior at a local pharmacy. His past medical history included coronary artery disease status post bypass grafting, bovine aortic valve replacement, sick sinus syndrome status post pacemaker placement, hypertension, paroxysmal atrial fibrillation, heart failure with preserved ejection fraction, chronic thoracic aortic aneurysm, chronic anemia, and stage IV prostate cancer status post retro pelvic prostatectomy followed by radiation therapy with subsequent recurrence with extensive bony metastases. Pertinent outpatient medications included abiraterone acetate, prednisone (5 mg daily), and leuprolide acetate. Patient had not recently started any other new medications or herbal supplements. Patient had received the coronavirus-19 (COVID-19) Moderna vaccine booster 1 month prior to admission and patient had received the Influenza vaccine 3 weeks prior to admission. Patient had baseline Karnofsky and Eastern Cooperative Oncology Group performance scores of 90 percent and 0, respectively. Patient was found to have metabolic encephalopathy and renal failure. His initial labs showed white blood cell count of 7.7 x 10e9 /L, hemoglobin 12.4 g/dL, and platelet count of 112 x 10e9 /L. His complete metabolic profile was normal, except for a creatinine 1.3 mg/dL, and total bilirubin of 2.2 mg/dL. Baseline labs from seven weeks prior were normal including a hemoglobin of 13 g/dL and a platelet count 201x10e9 /L. His last available total bilirubin three months prior was normal. During his hospitalization, his renal failure (Cr 4.1 mg/dL) and encephalopathy worsened, his hemoglobin and platelets continued to decrease, and his AST increased to 95 U/L with normal ALT at 36 U/L. Due to clinical deterioration with no clear diagnosis. Patient was afebrile with pulse rate 60 bpm, respiratory rate 19/min, blood pressure 191/ 108 mmHg, and acute hypoxic respiratory failure requiring 5 L Oxymask to maintain SpO2 more than 90percent. The physical exam was significant for bibasilar crackles in the lungs, jugular venous distention, trace pedal edema, asterixis, ecchymosis in the left upper extremity, and acute metabolic encephalopathy (Glascow Coma Score 9). Laboratory findings include the following (reference ranges listed parenthetically): hemoglobin, 9 g/dL (13.2-16.6 g/ dL); platelet count, 10 x 10e9 /L (135-317x10e9 /L); white blood cell count, 7.1x10e9 /L (3.4-9.6 x 10e9 /L); creatinine, 5.15 mg/ dL (0.75-1.34 mg/dL); total bilirubin, 2.5 mg/dL (less than 1.2 mg/dL); direct bilirubin, 1.0 mg/dL (0-0.3 mg/dL); lactate dehydrogenase, 3080 U/L (122-222 U/L); D-dimer, 33,652 ng/mL (less than 500 ng/mL); haptoglobin, less than 14 mg/dL (30-200 mg/ dL); immature platelet fraction, 15.7percent (1-7percent). Prothrombin time, activated partial thromboplastin time, and fibrinogen were within normal limits. Soluble fibrin monomer was positive. Complement levels on admission included a normal C3 and C4. Chest x-ray revealed bilateral pulmonary edema. Transthoracic echocardiography (TTE) was obtained to assess for the Waring Blender effect, which revealed no prosthetic or periprosthetic regurgitation. The differential diagnosis on admission for this patient with new-onset microangiopathic hemolytic anemia with anuric renal failure and metabolic encephalopathy included TTP, aHUS, disseminated intravascular coagulation (DIC), Waring-Blender syndrome secondary to paravalvular regurgitation, vaccine-induced thrombotic microangiopathy (TMA), or other causes of TMA. Non-TMA etiologies to explain the thrombocytopenia included vaccine-induced immune thrombotic thrombocytopenia (VITT) and heparin-induced thrombocytopenia (HIT). Heparin platelet factor 4 (PF4) antibody and Coombs test were negative. Peripheral smear revealed schistocytes (more than 10/hpf) and burr cells. ADAMTS13 and aHUS/TMA panels were obtained. Due to concern for TTP with multiorgan failure, plasma exchange (PLEX) and hemodialysis were promptly initiated. Given his stable respiratory status and no severe electrolyte abnormalities, PLEX initiation was prioritized over hemodialysis. After the initial PLEX session, the patient demonstrated significant improvement in mental status. Intermittent hemodialysis and prednisone (60 mg daily) were started subsequently. Rituximab therapy was held pending the ADAMTS13 result. The patient received eight sessions of PLEX in total with complete recovery of mental status to baseline within 48 hours. Prednisone (60 mg daily) was administered daily with PLEX until platelets reached 150x10e9 /L for 3 days, after which steroids were tapered over the next few weeks. ADAMTS13 activity results sent before PLEX returned at 67percent (normal more than 70percent) essentially ruling out a diagnosis of TTP, so rituximab was not administered. AHUS/TMA/complement panel returned with the following lab values: total complement 60 (normal 30-75 U/mL), C3 84 (normal 75-175 mg/dL) C4 28 (normal 14-40 mg/dL), factor B complement antigen 36 (normal 30-75 mg/dL), factor H complement antigen 24.7 (normal 18.5-40.8 mg/dL), alternate complement pathway function more than 110percent (normal more than 46percent), SC5b-9 complement 597 (normal less than 251 ng/dL). CBb complement more than 6 (normal less than 1.7 mcg/dL), and C4d complement 2.7 (normal less than 9.9 mcg/dL). Since this panel was not consistent with active alternative complement pathway activation and given the clinical improvement with PLEX, the patient was not started on eculizumab. On the day of discharge (day 11), platelet count was normal at 267x10e9 /L. By discharge, his renal function had not improved, and patient still required hemodialysis. After discharge, his atypical HUS gene panel results showed a double heterozygote status for CFHR1 exon 2-6 deletion, and CFHR3 exon 1-6 deletion. These specific mutations were not well-characterized and were of unclear clinical significance. After discharge, his clinical status continued to improve. Patient completed his course of prednisone, and his renal function improved to the point that patient came off hemodialysis. His most recent labs at 9 weeks post-discharge showed LDH within normal limits at 188 U/L, Hb of 11.4 g/dL, and platelets of 289x10e9 /L. ALT and AST within normal limits at 27 U/L and 33 U/L, respectively. Total bilirubin within normal limits at 0.5 mg/dL with no indirect hyperbilirubinemia. Creatinine normalized at 0.65 mg/dL. Author presented the case of a patient with microangiopathic hemolytic anemia, anuric renal failure and metabolic encephalopathy within 24 hours of administration of the new Arexvy RSV vaccine. Arexvy RSV vaccine data sheets do not report thrombocytopenia or microangiopathic hemolytic anemias to be known adverse events. The patient was heterozygous for a large deletion involving the CFHR1 and CFHR3 genes, strongly suggesting the presence of a contiguous deletion of the full CFHR1 and CFHR3 genes. Specifically, it was noted that the complement factor H (CFH)-CFHR gene cluster was prone to structural variation resulting in large deletions, duplications, and hybrids of genes within the cluster. Currently, the clinical significance of heterozygous copy number variation impacting the CFHR1 and CFHR3 genes was not well-characterized, and the clinical significance of deletions and duplications impacting other genes within the CFHR cluster was not well-delineated. The patient's complement levels were within normal range, except for elevations in CBb and SC5b-9. These complement-level abnormalities indicate activation of the alternative complement pathway, and in the absence of other complement abnormalities this was most likely secondary to post-blood draw activation. Of note, the expected a-HUS lab findings (low factor H, normal C4 and low AH50) were not present. However, prior studies have reported that complement levels may remain normal in aHUS.4 Classically, aHUS was not effectively treated with PLEX, although it was a first-line treatment for Factor H deficiency. RSV vaccine-induced thrombotic microangiopathy with associated multi-organ failure was a diagnosis of exclusion. High dose corticosteroids with PLEX resolved the patient's microangiopathic hemolytic anemia and thrombocytopenia and, in conjunction with intermittent hemodialysis, resolved the patient's acute renal failure.; Sender's Comments: A case of Thrombotic microangiopathy, Metabolic encephalopathy, Renal failure, Multiple organ dysfunction syndrome and Acute respiratory failure, less than a day after receiving Arexvy, in a 91-year-old male patient. Report is consistent with causal relation to the vaccine product, considering plausible time to onset and etiology (RSV vaccine-induced thrombotic microangiopathy with associated multi-organ failure was a diagnosis of exclusion) based on medical history.

The patient was 19 years at reporting time and last a year in Mar2024 she was 18, and she received a dose one of Trumenba, and she was supposed to return for the second dose on 02Sep2024, 6 months later but in the fall late September she was sick with a cold and they decided to give it a few weeks let her body build up a little bit more immunity, and then she got sick with the flu, and they had to wait again, and one thing led to another and here they were. It had been over a year since the first dose, and they were wondering what should do and if need to go back to the pharmacy for the 2nd dose and that was it or do they need to restart the sequence again, asking what would be the most effective way to go about this, asking if need to take the second dose or restart the whole schedule. No follow-up attempts are possible. Batch/lot number is not provided, and it cannot be obtained. More

Before administering vaccine, patient dad informed me that she fainted 2 years ago after receiving a flu shot administered by the school nurse. Nurse noted patient appeared anxious and attempted to calm her fears by explaining the procedure before administering vaccine. Patient was sitting next to dad and then moved to chair designated by nurse for immunizations; her father was sitting in front of her and held her hand during series of injections. She received two injections today, (TDAP and MCV). Both injections were tolerated well. After receiving vaccines, patient moved to sit next to her dad, she still appeared anxious but was talking and responding well to her dad. As I got up from the computer to retrieve the printed official copies of immunization records from the copier, I noticed patient suddenly lean forward and then passed out. Her fall was broken by the immunization chair she had just got out of, as she slumped toward the floor. Nurse and Dad grabbed her under each arm and placed her back in the chair, she immediately opened her eyes and made a retching noise. Dad states, "she's going to vomit." Nurse retrieved trash can and patient vomited into trash can. Nurse noted patient was diaphoretic and grabbed some paper towels, wet them with cold water and placed one on patient forehead and one at the base of neck. Nurse placed fan in front of patient to allow cool air to blow on her and assist with calming her down. She was allowed to sit with nurse for assessment, she then verbalized that she felt much better. She required no assistance upon leaving and office with her dad. No s/s of distress noted or voiced.

I continued to move arm as much as possible and also iced it off and on for an hour around 7/8 PM on the night of the injection. I began noticing the more I moved my arm the more it hurt. The pain was a deep intense burning and aching in and around the injection site including my entire shoulder area of my arm as well as into my supraclavicular lymph nodes. At 1:00 after waking up in pain at a 7 out of 10, I took two advil and was able to fall back to sleep. The following day symptoms had subsided to manageable soreness after taking another advil at 7:00am, and then again around 4:00pm. In addition to the pain experienced, my upper arm and lymph node on my left side were swollen. On Wednesday I noticed the swelling had not subsided and now my lymph nodes were red. I worked out this day with some intensity and had to leave feeling light headed. About 2 hours afer leaving the gym I started getting a migraine with auras. As of this time, Wed 27th I have not taken anymore advil and the pain level is around a 5 when raising my arm higher than horizontal. More

The lump is located beneath the skin and has not shown any signs of resolution. The area around the lump exhibits intermittent redness, which is sometimes severe and at other times absent. The lump is situated directly under the site of a previous injection given during her 4-month vaccinations. Despite the presence of the lump, she appears to be unaffected, maintaining her usual mobility. However, she has been more irritable than usual, a change that coincided with ear infections. She is currently on amoxicillin. The lump does not seem to cause discomfort when touched, and there is no evidence of drainage. She has also experienced intermittent fevers, which were initially attributed to teething. Her last recorded fever was 1 day ago, but since starting the antibiotic, her temperature has remained between 98 and 99.8 degrees. More

As the day progressed, he started with urgency and frequency in urination, nausea, vomiting, and then eventually urinary incontinence. We went to urgent care on 8/22/25 and they sent us to the pediatric ER. They did labs, urinalysis, and a CT scan. Ultimately, they decided to keep him overnight for a possible MRI the next day. However, his symptoms started fading away and within 48 hours completely gone. I questioned reporting these symptoms however I can't seem to contribute them to anything else.
