Hi pluskon,
Can you not contact your high school to get your immunization record? That is what I did, as my mother didn't have them. Also, the Public Health Department where you live or at least graduated from usually has a record of them. Luckily, my school does the immunizations for free for us, since we are charged a health service fee each semester. I ended up having to have an MMR.

It had to be the big one that I needed!! Good luck~
