Charts have been posted a number of times on this thread showing that mortality of most of these supposedly 'vaccine preventable' diseases declined dramatically before the vaccine was even developed.  But after nutrition and sanitation improved.

Also showing that things for which there never was a vaccine such as Scarlet Fever totally disappeared while things like poliomyasis seem to be being kept alive by the vaccines themselves.

Vaccines actually look a lot like snake-oil without needing to squint to hard.
