Well, I've had hep B done, because of my jobs. But, I had hep A (I think) done for India, but never went back for my booster for it to last 10 years or something like that. I'll ask my nurse at my doctors.
I'm only in Singapore for a week, so it's only a very short time to try to squeeze in everything. I've got a little book on the place, and it looks so damn nice!
