Right, the Vaccine Adverse Event System (VAERS) database shows raw reports before and after they're assessed.
Each report of an AE (an adverse event) has to be assessed for severity and likely cause. Severity gets graded on a 5 point scale, where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening (requiring hospitalization), and Grade 5 = death.
The Grade 3, 4, & 5 events also have to have cause evaluated. Again there is a 5 point scale, where Grade 1 = Unrelated to the Vaccine, Grade 2 = Unlikely, Grade 3 = Possible (cannot be ruled out), Grade 4 = Likely, and Grade 5 = Definitely Related.
The anti-vaxxers have willfully ignored this aspect of VAERS, and count all reports whether they've been assessed and evaluated, or not.
