"What the F.D.A. is doing and what the public thinks it's doing are as different as night and day."
Dr. Herbert E. Ley, former FDA Commissioner

  1. What is VAERS?

    VAERS is the Vaccine Adverse Event Reporting System for the United States. It is administered by General Dynamics for the U.S. Centers for Disease Control (CDC) and the U.S. Food and Drug Administration (FDA).

  2. What is the VAERS website

  3. Are reports to VAERS submitted by the general public?

    People and reporters who are unfamiliar with VAERS sometimes erroneously claim that VAERS reports are "self-reported" symptoms. Most reports are submitted by medical personnel and that can easily been seen by reading complex medical jargon in the free-form symtom text section. The reports related to death are clearly not self-reported. However, there are definately some reports submitted by the general public.

  4. Are people submitting fake adverse reaction reports to VAERS.

    It is a U.S. federal crime to submit a fake report to VAERS. Even with the threat of federal prosecution, there will always be some law-breakers. People who would like to discredit VAERS would be the most likely to submit obviously false reports.

  5. What makes VAERS one of the most unique and important adverse reaction tool in the world?

    • It is one of the only tools where researchers, physicians and the general public can read and query all of the details of adverse reaction reports, including the notes as entered by independent medical personnel.
    • It empowers individuals to read through full reports (not just biased summaries) and make their own decisions for themselves and their family.
    • It allows physicians to read through case details to help them with recommendations for their patients.
    • Most other countries provide biased summaries to the public. Sometimes, cases from physicians can be rejected by these governments or by private companies based on government agency guidance documents (Canada). Sometimes the governments sign lucrative deals with drug manufacturers (Canada, Israel).
    • Drugs companies want to eliminate VAERS because the public has access to data outside of their public relations campaigns.
    • Government bureaucrats who are part of the revolving door between drug companies and government agencies want to eliminate VAERS.
    • Foreign governments who simply provide biased and incomplete summary information want to eliminate VAERS as it can be used to advocate for the general public.
    • Politicians who accept drug company lobbying money want to eliminate VAERS.
    • Certain social media companies that want to control the narrative for their drug company partners/advertisers want to eliminate VAERS.
    • Media companies who constantly accept large amounts of advertising from drug companies want to eliminate VAERS and regularly publish biased "fact check" articles for the drug companies.

    While VAERS isn't perfect, it is enormously useful and any attempt to eliminate it will be at the direction of drug companies and their corrupt government and private partners. If that happens, the data published by the government and media will be worthless (at best).

  6. Is it false to claim that all VAERS reports are caused by one or more particular vaccines?

    Yes, not all cases listed in VAERS are caused by COVID-19 vaccine drugs, even though most cases are submitted by medical personnel. Some of those reactions may be conincidental and some may be caused by the COVID-19 vaccine drugs. In order to get accurate idea of cases caused by COVID-19 vaccine drugs, please carefully read the next three FAQ answers below related to 1) this website's methodology of calculating case totals, 2) VAERS backlogged cases; and most importantly 3) the VAERS reporting rate. If you carefully read through the answers to the three questions below, you will know more about COVID-19 vaccine drug cases and VAERS than most.

  7. Why do the numbers of reported COVID-19 vaccine drug adverse reactions from VAERS vary from website to website?

    The methodology used on this site total calculate total cases is as follows:

    1. Every Friday, this site downloads the raw VAERS data from VAERS in CSV file format.
    2. The number of cases found in the "2021VAERSDATA.CSV" file is linked by VAERS_ID to the same VAERS_ID in the "2021VAERSVAX.CSV" file that has a vaccination type of "COVID19".
    3. There are a small number of cases (approximately 0.1%) where the vaccination type is "UNK" (Unknown), but the symptom_text field in the "2021VAERSDATA.CSV" file indicates that it was a COVID-19 vaccine drug. On the December 10, 2021 download, this amounted to 1,182 of 693,065 total cases. These cases are added to the total.
    4. The totals for each symptom (death, blood clots, etc.) is calculated based on the table created from steps 1-3 above.
    5. This site only counts the deaths and adverse reactions listed in VAERS from the United States. As of December 10, 2021, there are 10,949 foreign deaths from COVID-19 vaccine drugs reported to VAERS that is not included in the total listed on this site.

    There are some sites that may get their totals from an independent aggregator such as OpenVAERS and Others may use the VAERS interactive tool to get totals. Some may not query the symptom_text to find other cases (as in Step #3 above) and some site may have more sophisticated queries that pick up small numbers of cases that are missed here. Finally, some sites may inadvertently count more than COVID-19 vaccine drugs in their total.

  8. How do you know that there is a large backlog of cases that have been submitted to VAERS, but not made available to the public?

    It is important to understand that each submitted case is given a sequential VAERS_ID number. In addition, there is a date field, RECVDATE (Received Date), to indicate the date it was submitted to VAERS. If you download several
    raw data files from 2021 and look at the csv file named "2021VAERSDATA.CSV" in each of the downloads, you will see many large gaps in the VAERS_ID numbers. The image on the left below shows a large VAERS_ID gap that could be seen in the April 30, 2021 data. The image on the right shows the gap filled in on May 7, 2021 for items received in February. Currently (December 10, 2021), there are 302,111 missing VAERS_ID's. These gaps are being filled by more than 10,000 cases every week that had already been received by VAERS weeks or months earlier. New gaps in higher VAERS_ID numbers are created each week that offset some of the gaps that are filled.

    In order to see the gaps and how the gaps are filled every week, it is necessary to download several raw data files from 2021. There are other ways that investigators have seen gaps in data, such as by showing a huge decline in cases at some points of time when the distribution of COVID-19 vaccine drugs was increasing. (See this video, for example.)

    What is just as important as a backlog of 302,111 missing cases in VAERS is that fact the CDC did not tell researchers, doctors and the general public that most of the submitted cases from 2021 have not yet been uploaded to VAERS! They presented the data as if it were up-to-date through December 10, 2021. The truth is only 71% of the submitted cases in 2021 have been made available.

    Since February 1, 2021, approximately 5.73% of cases are for non-COVID-19 vaccines. Starting on May 10, 2021 the calculations on this site estimate that 99.6% of the backlogged cases are related to COVID-19 vaccine drugs. (284,800 out of 302,111 backlogged cases in the December 10, 2021 VAERS data)

  9. Why is the VAERS reporting rate the most important number to know in order to estimate the prevalence of a COVID-19 vaccine drug-linked symptom (or death) in the United States?

    If you were to start a website to collect lung cancer cases from heavy tobacco use and then receive only five (5) cases in a one year timeframe, you might be tempted to proclaim that heavy tobacco use is fairly "safe," right? Wrong! You would know that those five cases represent only a small fraction of cases in the United States because the reporting rate to your website would be low. There may be countless thousands with tobacco-caused lung cancer who do not report to your website.

    Similarly, the reporting rate to the VAERS website is key to estimating the number of total number of cases (reported + unreported) in the United States. There are eight (8) pieces of evidence that point to a VAERS reporting rate of approximately 1% to 5%. If the reporting rate is 1%, then the actual number of reactions must be multiplied by 100 to determine the actual total number of adverse events. If the reporting rate is 5%, then multiplying by 20 will give you the actual total number of adverse effects.

    1. Harvard researchers found that less than 1% of adverse vaccine drug reactions are reported to VAERS. See the last two paragraphs of the Results section on page 6 of
    2. Research looking at 64,900 persons who received the Pfizer or Moderna mRNA vaccine drug found the rate of serious anaphylaxis reactions was 50-100 times more than what was reported to VAERS. In other words, anaphylaxis reactions reported to VAERS represented only 1-2% of all anaphylaxis reactions after injection with the COVID-19 vaccine drugs.
    3. The U.S. Centers for Disease Control (CDC) presented in a slideshow on page 35 that they believe that only 1.13% of deaths expected at Long-Term Care Facilities (129 out of 11,440) were reported to VAERS after a COVID-19 vaccine drug injection.
    4. A former FDA Commissioner, presented a report showing a 1% reporting rate for serious adverse drug reactions even when those reports are required.
    5. Steve Kirsch (Dir COVID-19 Early Treatment Fund), Jessica Rose, Ph.D. (Researcher) and Mathew Crawford (Statistician) published a paper, Estimating the number of COVID vaccine deaths in America showing an approximate 2.44% reporting rate of serious adverse reactions (including death) to VAERS.
    6. Data from the Centers for Medicare and Medicaid Services (CMS) system provided by a whistleblower was used to analyze the underreporting factor for VAERS. The reporting rate for all reactions to VAERS was estimated to be 2.2%. See video for original imformation about CMS whistleblower.
    7. Rose and Crawford published a paper that estimated the reporting rate of serious adverse reactions to VAERS is less than 2.5%.
    8. Recent research from Columbia University showed that deaths are under reported to VAERS by at least a factor of 20.

    The key point is that the reporting rate for VAERS adverse reactions are between 1% and 5% (1 to 5 in every 100 cases are reported). The reporting rate may be slightly higher for more severe reactions like death or anaphylaxis and slightly lower for less severe reactions.

    Example: To estimate the number of cases of death in the U.S. linked to COVID-19 vaccine drugs, it would be calculated as follows:

    • 9,334 deaths reported to and published by VAERS as of December 10, 2021.
    • 3,835 estimated deaths cases reported to VAERS, but backlogged and not yet published as of December 10, 2021.
    • 13,169 total cases (published by VAERS and backlogged) of death linked to COVID-19 vaccine drugs submitted to VAERS as of December 10, 2021.
    • 1,316,900 Total Death Cases (Reported + Unreported) as of December 10, 2021 if we use a 1% reporting rate.
    • 1,165,398 Total Death Cases (Reported + Unreported) as of December 10, 2021 if we use the CDC's estimate of 1.13% reporting rate.

    This does not mean that all 1,316,900 (or 1,165,398) cases of death after an injection of a COVID-19 vaccine drug are caused by the drug. It is likely that some percentage of the cases are coincidental and some are caused by the drug. There are a couple of ways to get an idea of whether a significant percentage of cases are caused by the COVID-19 vaccine drugs:

    1. Compare the number of VAERS-reported cases of death or a symptom linked to COVID-19 vaccine drugs to the number of cases of VAERS-reported symtoms or death from flu vaccines (which were also injected well over a hundred millions times per year). If there is an unusual spike in reports only for COVID-19 vaccine drugs, then there is likely an enormous problem.

    2. Look through the symptom text provided for each symptom on the data webpage (or query the VAERS database itself) to see if many of the cases seem related to the COVID-19 vaccine drugs. A more sophisticated process would be for teams of independent experts (outside of the drug industry and government) to look at the cases in more details. An appropriate team would be limited to researchers who have, prior to April 1, 2021, publically called for more independent research and have no conflicts of interest. However, with 693,065 cases reported and 284,800 cases reported but backlogged (as of December 10, 2021), a more sophisticated process could take years.
