Best of luck.
My Hep B vaccinations (from the USA) failed to work, so I'm getting a new round at one of the nicest hospitals in Dongguan. At least they have Hep B shots. I'll be getting a full hep panel a few months after finishing and see if it worked this time. I'll also have that done at least once per year to make sure it keeps working.
They don't carry Hep A vaccines or anything else, except Rabies, for which they don't seem to fully get the concept of immunization vs treatment.
I've heard rumors of a "special" hospital just for vaccinations, but haven't managed to hunt it down.
Hopefully Nanjing will make this easier.
BTW - Cipro for diarrhea? Whatever is your doc smoking? Bring some Pepto Bismal tabs and at least one other over the counter treatment. Once you get past your first few rounds visiting the street vendors or super-spicy Hunan restaurants, you should be fine.
