One of the ways we learn about adverse events from approved vaccines is the CDC’s Vaccine Adverse Event Reporting System (VAERS). From the VAERS website:
“VAERS is a national early warning system to detect possible safety problems in U.S. licensed vaccines... VAERS accepts and analyzes reports of adverse events (possible side effects) following vaccination….
“VAERS is not designed to detect if a vaccine caused an adverse event, but it can identify unusual or unexpected patterns of reporting that might indicate possible safety problems requiring a closer look.”
It was created by the 1986 National Childhood Vaccine Injury Act that limited vaccine manufacturer liability for vaccine injury and created a national system of vaccine injury compensation, which has paid out about $4.5 billion since its creation.
Because it is passive (reports are made voluntarily) and most people are unaware it exists, adverse events following vaccination are underreported. The rate of underreporting is currently unknown, but based on available evidence it is very high:
They never had a chance to test the system they developed against VAERS, because “the necessary CDC contacts were no longer available and the CDC consultants responsible for receiving data were no longer responsive to our multiple requests to proceed with testing and evaluation.”
As of April 1, 2021
Although VAERS cannot be used to conclude a causal link between vaccination and an adverse event, it is used to monitor vaccines for safety “signals.” What kinds of signals are being reported?
Total DEATHS reported for COVID-19 Vaccines: 2,342* Total number if 30x underreporting: 70,260 Total number if 99x underreporting: 234,200

Reported deaths by days since COVID-19 vaccination (VAERS as of 4/1):*

According to this news article from Feb. 18, the death rate per COVID vaccine dose is much higher than the flu vaccine this year:
“According to [VAERS], there were 21 deaths this flu season after 180+ million flu vaccines, a rate of 1 death per 9,000,000 vaccinations. The COVID-19 vaccine, however, according to VAERS, shows 1 death reported per 35,000 shots or 10,000 completed vaccinations (so far), a 300-900 greater likelihood.”
* The 3-5 cases of deaths reported prior to the vaccine’s testing and rollout likely reflect a reporting error.
Actually, the Israeli Ministry of Health just announced an investigation into reports of inflammation of the meninges and the heart muscle (including pericarditis and myocarditis) in people shortly following vaccination. (It is worth noting that 20% of VAERS reports for COVID-19 vaccines were cardiac-related.) But these are only a fraction of reported events. The investigation needs to be expanded to include ALL morbidity and mortality.
The Israeli government could easily do this, because their health records are highly centralized, and they know whether and when people were vaccinated and if they had any documented health problems after. They already used the data to publish a (flawed) study of the vaccines’ effectiveness. If they wanted to put this issue to rest, they could, but as of this writing they have not.
Why not?
