Looking back over the data

Hi again.
Meryl and her colleagues have been at it again.  Well, they've been at it for some time, but it's taken me a little while to get onto it.  They've published several times graphs that show that several diseases were falling in incidence before vaccination programmes came about.  They propose that vaccination programmes had no effect, but just benefited from the natural decline in incidence.  In contrast, I came across the following table :

Soooooo what does it tell us?  Simple.  Before vaccination rates these five diseases were rampant, and deaths common.  Note - this goes back to the 1920's.  Compare the red and the green bars in each column.  Vaccination programmes had a profound effect on death rates.
Come on AVN - you really don't believe that stuff on your website, do you?
