There is rapidly spreading outbreak of measles which makes news right now - 250 cases. Measles are that rare now It is super contagious, so yes, prior vaccines everyone got it. Mortality is 1-3 in 1000 of sick. Plus some people get deaf and some get brain damage (dunno how many now). So, nowadays super rare, used to be normal and harmless is not a word I would use for someone that kills 1-3 in 1000 kids.
