The Vaccine Adverse Event Reporting Service (VAERS) numbers are disturbing, and they undoubtedly under count. From Jon Rappoport at lewrockwell.com:
A long-standing private organization, the National Vaccine Information Center, has analyzed the US government’s database, the Vaccine Adverse Event Reporting System (VAERS).
As of May 7, 2021, VAERS lists 192,954 adverse-event reports associated with COVID vaccines. 
These events cover the spectrum from mild transient effects to death.
VAERS has always has multiple problems.
One: Doctors aren’t required by law to report adverse effects. Many of them wouldn’t risk blowback by doing so.
Two: There is no comprehensive effort to determine whether an adverse effect is actually caused by a vaccine.
Three: Patients can make adverse-effect reports—but are often hesitant to do so.
Four: By far the biggest problem is: most Americans aren’t even aware that VAERS exists.
Therefore, on balance, UNDER-REPORTING adverse effects is the primary defect of VAERS.
Many efforts have been made to estimate the degree of under-reporting. These estimates state the VAERS numbers should be multiplied by 10, all the way to 100, to obtain an accurate picture of adverse effects.
Ten times the current number of COVID vaccine adverse effects would equal 1,929,540. A hundred times the current number=19,295,400. Either way, the number is staggering.
The death reports are escalating by the day. As of May 7—4,057.
