Vaccines don't work. A 2011 study conducted in cooperation between Devlin-MacGregor Pharmaceuticals and the A. Jude Robinson Institute (presided over by Dr Charles Nichols no less) tracked a group of over one hundred hypochondriacs who were inoculated with a placebo vaccine, and compared their results with a control group of faith-based abstainers, inoculated with the power of prayer. No difference. The study made no difference. It couldn't be any clearer.
Vaccines? No good. Don't work.
