The antivaxxers always say these diseases were declining anyway because of “improved sanitation” (despite the fact that measles, for example, is airborne). Now of course that chart puts the lie to that—plus, I was around and I don’t remember the Hygiene Revolution™ of 1963.

(Different years for different diseases, too.)

IIRC, the widespread purchases of vacuum cleaners had a huge impact as well.
