The difference in VAERS reports is due to a much broader reporting regime. Most vaccines have a set of well-known complications and specific reporting requirements based on those events and their known time frames. For covid, any severe event after vaccination is reportable, even if there’s no reason to believe the vaccine was the cause.
This is good policy and moves towards more robust medical data practice, but it means VAERS statistics for covid vaccines are not comparable with those of other vaccines.
