I remember getting shots but I don't remember any drama about them or kids not having them. If that concerned existed in the 80s, I was ignorant of it.
I had another thought last night... The idea of clustering non-vaccinated kids in a confined area is probably a really bad one too. In some of these stories you see isolated innocents that were either controlled or vaccinated people served as a "break." Create a special school/community of unvaccinated kids and there would be no breaks, it would ripple through that entire community.
