CDC Data Show 1.6 Million Adverse Events and 50,000 Blood Clotting Disorders Following COVID-19 Vaccination

Data from the Vaccine Adverse Event Reporting System (VAERS) released Friday show 1,637,411 adverse events following COVID-19 vaccines were reported between Dec. 14, 2020, and April 26, 2024. This includes 314,353 reports of serious injuries and 37,544 deaths.

Of the 37,544 reported deaths, 23,356 cases are attributed to Pfizer, 10,754 to Moderna, and 2,878 to Johnson & Johnson. Of the reported deaths, 9% occurred within 24 hours of vaccination, and 13% occurred within 48 hours.

VAERS is a voluntary reporting system comanaged by the U.S. Food and Drug Administration and the Centers for Disease Control and Prevention. It is designed to detect vaccine safety signals, although it is estimated to represent less than 1 percent of actual adverse events.

According to the CDC, VAERS data available to the public include the initial reports to VAERS. Any updates or corrections to reports during follow-up are used by the government for analysis but are not made available to the public. In other words, we may see an initial report for a heart problem that later leads to death, but we will not see an updated report if a person dies, nor will that death be included in the statistics.

Excluding “foreign reports” to VAERS, 1,010,545 adverse events, including 18,862 deaths and 117,476 serious injuries, were reported in the U.S. between Dec. 14, 2020, and April 26, 2024.

Foreign reports are reports from foreign subsidiaries sent to U.S. vaccine manufacturers. Under FDA regulations, if a manufacturer is notified of a foreign case report describing an event that is both serious and does not appear on the product’s labeling, the manufacturer must submit the report to VAERS.

Data for 6-month-olds to 5-year-olds

Data for 5- to 11-year-olds

Data for 12- to 17-year-olds

Data for all age groups to VAERS

  • At least 15% of deaths were related to cardiac disorders.
  • 53% of those who died were male, and 41% were female. The remaining death reports do not list the gender of the deceased.
  • The average age of death was 72.
  • As of April 26, 9,386 pregnant women reported adverse events related to COVID-19 vaccines, including 5,453 reports of miscarriage or premature birth.
  • Of the 18,054 cases of Bell’s palsy reported, 78% were attributed to Pfizer vaccinations and 21% to Moderna.
  • 3,598 reports of Guillain-Barré syndrome.
  • 10,751 reports of anaphylaxis where the reaction was life-threatening, required treatment, or resulted in death.
  • 9,117 reports of myocardial infarction and cardiac arrest.
  • 49,942 reports of blood-clotting disorders. Of those, 34,459 reports were attributed to Pfizer and 11,332 reports to Moderna.
  • 26,996 cases of myocarditis and pericarditis, with 20,572 cases attributed to Pfizer and 5,880 cases to Moderna.

    The CDC uses a narrowed case definition of myocarditis. To meet the case definition, people must have “symptoms such as chest pain, shortness of breath and feelings of having a fast-beating, fluttering or pounding heart, and medical tests to support the diagnosis of myocarditis and rule out other causes.” This allows the CDC to exclude cases of cardiac arrest, ischemic strokes, and deaths due to heart problems that occur before one has the chance to seek medical attention or obtain a diagnosis.

    The CDC website does not state what happens to these cases, but there is no indication they are tracked or included in the CDC’s myocarditis numbers.

  • 91 cases of Creutzfeldt-Jakob disease, with 76 cases attributed to Pfizer and 15 to Moderna.
  • 1,065 cases of POTS, with 703 cases attributed to Pfizer.

Although healthcare providers are required by law to report vaccine adverse events to VAERS, research shows very few do. It is essential that anyone who experiences an adverse event report their own injury.
