There's one ingredient you missed.
In order for whoever did the reporting, to correlate the death with the vax, the person injected must have *died*.
Kinda hard to miss that one.
Events are easier because the person can self-report. How many do? I just showed an analysis (see above) that shows that only 0.1% of people have reported their fever into VAERS. Part of that is because people expect fever and don't consider it adverse. But part of it is they have no idea there is a VAERS system, too lazy, etc.
The bigger question with events is the serious events. If someone has a heart attack and goes to the hospital, how many of those are reported? I presume that in the 15 minute waiting period, anyone with a heart attack in the waiting area should be reported. Are they? No idea. But they should be reported for VAERS to have any credibility.
What about the next day? Does the ER guy ask when the heart attack victim had their shot? Don't know but it's probably not the ER guy's first priority. Mostly going to try to help the patient.
