How was Lisa never vaccinated against the Mumps? That has always bothered me.
Currently, mmr is about 86% effective against mumps. It may have been less so in the 80s. Also, she may have only had one round of shots. Could be she was just unlucky, and her immune response wasn't strong enough. It's not unheard of.
