I agree with you that VAERS is massively underreported, and so does this study: https://rickjaffeesq.com/wp-content/uploads/2021/02/r18hs017045-lazarus-final-report-20116.pdf
"fewer than 1% of vaccine adverse events are reported"

I've heard of more people injured or killed by the "vaccines" than injured or killed by Covid. Many people I talk to have the same experience. Far more issues with the vaccines than the virus. But those are anecdotes, so I keep going to the data, to see if my experience is typical, or if I need to trust the official narrative that the injections are safe and effective.

VAERS is the big database of injuries and deaths. As you can imagine, it is VERY hard to get doctors to go on record to attest the Covid "vaccine" was responsible for killing their patient. But that is required in order to submit a VAERS report, and it has already happened more than 17000 times (just in the USA). Those who claim "anyone can file a bogus VAERS report" are either ignorant or lying.

2000 are being added every month, and accelerating, so there will be at least 22000 by Christmas.
We know less than 1% of injuries and deaths make it to VAERS, so the actual number of deaths could be over 2 million already.

700,000 is the inflated Covid death count in the USA, so it appears there are roughly 3 people dying from the "vaccines" for every 1 person dying of Covid. This matches my real world experience.

Imagine mandating an injection more deadly than the illness it doesn't even prevent?

And yet, whenever I bring this up to pro-vaxxers, they come back with "VAERS is unverified, so we have no way of knowing if any of those deaths are actually linked to the vaccines".
