Vaccines for you

So a lot of people talk about not vaccinating their children, but what about yourself. I just got back from China and two of the vaccines I needed for that country were Hep A and Typhoid both of which you can get from just drinking contaminated water. And I remember as I was drinking water in a restaurant being so thankful that I didn't have to worry about the water in my cup or the water my food had been cooked in because I knew the vaccine protected me. So I'm asking, if you needed vaccines to go to another country or simply it was a good idea to get certain vaccines to protect yourself, would you get them?
