More Thoughts on the VAERS Pre-Print

How not to report about vaccine safety issues, Toronto Star edition

Gold mine or dumpster dive? A closer look at adverse event reports

All informed health decisions are based on an evaluation of expected risks and known benefits. Nothing is without risk. Drugs can provide an enormous benefit, but they all have the potential to harm.
