re: #12 DangerMan

they went from:
- some vaccines may have once contained mercury
- some vaccines may not have been fully and adequately tested on humans
etc

to

- all vaccines are evil

The old chestnut of “no double-blind trials.”

To conduct a double-blind trial of a vaccine, you would need to give some people the vaccine being tested, and other a placebo, then expose them all to the disease being tested and see who gets sick.

That is deeply unethical, but try to explain that to an antivaxxer.
