I have heard of German Measles parties, not that I went to one but people liked girls to catch it because it's dangerous for pregnant women so best to get it out of the way. It's not a horrible, serious illness, doesn't last long. I remember having it but there's a vaccine for it now. I also had measles although I'd been vaccinated but it was mild, and whooping cough & chicken pox. I don't think there was a vaccination for chicken pox.
Sririam we vaccinate for smallpox, TB and polio and it's possible to be vaccinated against meningitis. People over sixty have an anti influenza jab if they want, also those working in certain professions who are at risk.
I don't know why you say the measles vaccine is ineffective, sririam. The disease has been virtually eradicated because of it and if a child does catch it, it's very mild indeed.
