If you think VAERS can't be used to determine causality...

think again.

Here’s a an editorial written by my good friend James Lyons-Weiler entitled, “If Vaccine Adverse Events Tracking Systems Do Not Support Causal Inference, then “Pharmacovigilance” Does Not Exist.”

Suffice it to say that it is a big mistake to take statements from the CDC about what you can and cannot do with VAERS data at face value.
