Since it looks like they filmed at least 2 movies on the ship I have a feeling RC was not paid but did it for the free advertising...however I could be wrong.
That's right - I had all three of those diseases as well, before the vaccines came out. That was when the doctor would make house calls. (boy, am I aging myself!) And the polio vaccine was a yearly shot.
Back in the day there was no MMR vaccination. I had measles, mumps and rubella before the shots came out. Having had 6 kids in the house, we could never escape the childhood diseases when they came home from school with them. Supposedly one has immunity after contracting the disease.
