Vaccinations:

Hep A (you may already have this)
Hep B
Rabies (if you feel like you need it)
Typhoid (only if you’ll be in a tropical climate)
Japanese encephalitis (not something I’ve heard of before, and have never received)

You’ll probably want to get a tetanus booster.

All I ever got on my multiple trips to China was Hep B vaccinations. Fortunately I had a tetanus shot stateside and thus didn’t need one when I gashed my leg on some rusty fence out there. Not that such a thing would ever happen to you, of course. ;)
