Chicken pox in kids is usually mild. Mostly just a nuisance. For adults is usually worse.
Measles extremely contagious, about one in a thousand will die and more may suffer permanent damage although it isn't always obvious. For instance immune system may be slightly weaker. May be slight brain damage.
Polio is contagious. From one in a hundred to one in a thousand can end up with serious, life long nervous problems, paralysis. Can strike in childhood, go into remission, and return in adulthood.
All three have vaccines.
