Yup...Mumps at camp in 78 and measles in High School in 81. My mom was a Ped nurse and get me everything under the sun...even those vaccines not on the schedule. She also kept meticulous records. I had 3 MMRs. Can you guess that I'm one of those that didn't seroconvert?
Back when I had CP back in the Late 60's it wasn't even considered a disease...no one ever freaked out about it...we just waited to get it and get a school vacation!
The CP vaccine was never intended for the general population. It was conceived for the immune-compromised. When they weren't making enough money off of it, they had it added to the childhood vaccine schedule and put out fearmongering campaigns to promote it.
If you ask people who grew up in the 40s - measles and mumps were no biggie...then came the vaccine and they were terrorizing to the people who grew up past the 60's. The same is true for CP...it was no biggie until the vaccine came out.
There are lots of illnesses that suck...if there is no vaccine, no one freaks about it.
My mom got measles, mumps, and rubella as a kid...and she's fine. I remember her telling me stories about her sister looking funny when she had mumps (swollen face).
I've also only had the flu a handful of times in my life...AND I got viral meningitis (and my mom got it after me) and turned out fine.
