When I decided to go "back" to school, I had to have proof of immunizations - measles, mumps & rubella (MMR), and having the diseases was not considered immunization. When I was little, these weren't mandatory like they are now. We could not find where I had gotten the series, so I had to get them. I opted for the meningitis shot, as well. UMD (and other colleges, I'm sure) has a history of someone getting it every couple of years. I figured, with my luck, the person would be sitting next to me in class.
And sneeze on me.
And not in a good way!
It's funny because I also had to show proof of immunizations when I started taking the paralegal classes. Mind you, this was the same school where I had worked for almost 10 years. They didn't seem to be bothered with such things when I was hired, but if I wanted to sit next to students instead of stand in front of a classroom and yap at them, then I had to show I'd had my shots.
When I was a kid, I had the mumps about 2 days before I was supposed to get the shot, so my records showed no record of mumps immunization. I had to go get a ... shoot, what was the term? When you do a blood test to check for antibodies? Damnit, my memory is not cooperating so Mr.Google told me that it's called a titer.
