What does being "pro-vax" mean?
That you believe in any claims of vaccine efficacy made by the manufacturers or the FDA and are more then willing to have them injected into your body?
It probably means that you take the statistical evidence produced by massive double-blinded placebo-controlled randomized clinical trials as actual evidence
If you don't believe every developed countries’ medical bodies on vaccines, where do you get your info on this? (As to the ‘pro-vax’ question, I'd define it as someone who is open to listening the medical bodies of every developed country on the planet.)
