I hear that a factor of a 100X is common. The system is made so that the least amount of effect are reported.

Personally I know someone who had a heart attack 3 day after second dose (60yo female) The doctor dismissed the possibility of a causation by the vaccine, this case is not reported even if the person almost died.

Is covid still worse than the vaccine with Omicron, I don’t know, probable. But I know that most side effect are not reported.

A crazy thing is that the Myocardis rate can be reduce 3X by a 2 second procedure at vaccination (verifying that the injection is not in a vein)

Yeah. My partner got a moderately severe skin rash after her Moderna vaccine. She tried to report it but was ignored by everyone. Now it finally comes out that Moderna can cause severe skin rashes...

VAERS is only one data source and not a particularly good one. We have vaccination records linked to medical histories in electronic health record systems and insurance claims databases.

Right, it sucks, but EMR systems are private and not accessible for research by public entities.

Vaccine Safety Datalink is a much better source.

RAW VAERS data is a POS source of data. Plenty of Anti-Vaxxers submit false data to it and even non Anti-Vaxxers submit symptoms that correspond to anything within a month of taking the shot.

It's probably true that cases are under reported in both groups. Many people with myocarditis might just go along with their day because the symptoms aren't especially worrisome to them. You can imagine the cohort of people with political affiliations that say COVID isn't worth worrying about might not see a doctor even if the symptoms are worrisome.
