I've noticed in a lot of the shows of the 50's, measles, mumps, and chicken pox are treated as no big deal, and nothing more than a childhood nuisance. Societal attitude sure has changed in the last 60+yrs. Even when an adult contracted one of those on tv, it was no big deal either. The shows didn't have the parents worried senseless, screaming like a maniac over catching an illness, nor did it alarm an entire neighborhood.
Yesterday on Green Acres, a joke was made about someone paying for everyone's flu shot, as tho it were some kind of medicine only the priveleged should have access to.
