Was reading about the "safety" testing that was carried out on the HPV vaccine that is soon to be made compulsory for girls (completely unnecessary if they've got any understanding of sexual hygene).
They tested the vaccine against the vaccine sans the bugs, i.e. the adjuvents and aluminium chemicals were injected into the control group as well.
Lo and behold, the vaccine had no more reactions than the control.
(like testing aspartame against a control of MSG)
