Good on you! A lot of westerners who are against all vaccines forget what it's like when we didn't have them. I got my polio vaccine when I was little (I don't remember it, but I have my vaccination card from childhood), but I think back then it was an injection.
I mean, we even had a president here in the US who was in a wheelchair from polio (FDR, the president during WWII) who hid it from the public by strategically posing for photos only when he could lean on things to stand up and never, ever letting photographers take his photo when he was in his wheelchair.
