Anyone can report to VAERS. Evidenced by the reports if you care to peruse them. There are a lot of gems like, "he got the vax and then just died" and "my baby died a few weeks after I received the vaccine" and my favorite, "my cat died a few days after I got vaccinated". Considering the infinitely higher level of publicity that VAERS has received for this vaccine vs all previous vaccines, my guess is that it is over-reported.
