The “Bradford Hill tenets of causality,” which McCullough refers to in the video, were established in 1965 by Sir Austin Bradford Hill, an English epidemiologist. “When clinicians have actually reviewed death certificates, autopsy details, and medical records, an exceedingly small number of deaths has been deemed to be causally associated with the vaccine,” Jason Salemi, an associate professor of epidemiology at the University of South Florida, told the AP in an email. Those cases were causally associated with rare blood clots caused by the Johnson & Johnson shot. The CDC has confirmed just nine deaths caused by COVID-19 vaccines. VAERS identifies unusual patterns that can help alert medical professionals to probe further. No vaccine is 100% safe or effective, and rare adverse events are possible. While VAERS has many limitations on how its information can be used, the database is considered a first step in detecting issues and concerns that can then be investigated, experts have told the AP. Health care providers and manufacturers are also required to submit adverse responses reported after vaccines, even if they don’t know whether the vaccine caused them. The system is passive, meaning people self-report their information. VAERS allows anyone to submit reports on any possible reactions after a vaccine, and has clear disclaimers that reports may “contain information that is incomplete, inaccurate, coincidental, or unverifiable.” Regardless, posts citing VAERS data to cast doubt on the safety of the vaccines leave out the important context that adverse events reported to the system are not verified, as the AP has reported. Martha Sharan, a spokesperson for the CDC, confirmed the most recent VAERS numbers on deaths, noting that they are “unconfirmed reports.” 4, the most recent data available, that number was up to 18,533. 23, the number of people reported to have died after COVID-19 vaccination had increased to 18,007 based on preliminary reports submitted to VAERS from Dec. But the figure he uses is closer to the CDC’s numbers from September. McCullough, who did not respond to a request for comment, does not specify in the video where the CDC reported the data that he cites.
