I’m not going to ask anyone to compare polio to what we are facing today as it’s against the rules. However, what convinced so many parents to vaccinate their children against polio? Were there difficulties in convincing parents to vaccinate their children?
There's always more that can be said, but I get at some of this in this answer to a question about vaccination efforts in Texas. /u/jbdyer and I provide more context about polio here.
