I had mumps as a 5-year old before there was a vaccine. Not a pleasant experience and they settled around my heart, getting me a week or better stay in STL Children's Hospital. Of course, others had them settle in their testicles which wasn't pleasant. Or they could end up with meningitis and permanent hearing loss.
