Make sure u get your Hep-B Vaccines. i am telling you this bcos most of the chinese population shows positive for Hep-B..
Well get all possible vaccines in order to make sure u are on a safer side.

i think you only need keep your body safety without any epidemic disease should be everything all right if you only travel around the china big citys.

the shots,,there is no reporting for having them,, I do recommend them,,, there is a questionaire about where you come from and are you healthy on the plane.

You never know what can make you sick,, I saw the boat tour on the Li river and the crew were washing the dishes after wards in the river,, something like that could spread Hep. I think Hep B can be spread in restaurants. resulting in many getting sick.

Contrary to what some have said here, you can't rely being in a big city for safety. Even in Beijing, Shanghai or Shenzhen, you're just as likely to catch something. Not typhoid, obviously, but still.

As far as recommended vaccinations, here they are:

* Routine immunizations should be up to date. These include
o Tetanus-diphtheria (DPT)
o Measles/Mumps/Rubella (MMR)
o Varicella (chickenpox)
* Hepatitis A is recommended for all travelers over 12 months of age to China.
* Typhoid is recommended especially if you’ll be in rural areas where you may eat or drink outside large restaurants and hotels where you may come in contact with contaminated water or food.
* Yellow Fever is required by Chinese law only if you are arriving from an infected area such as Africa.
* Japanese Encephalitis is recommended for longer-term travelers, especially children, who are susceptible to mosquito bites and will be outdoors during mosquito season (which can last from May to November in southern China).
* Hepatitis B is also recommended for longer term visitors/residents as it is very common throughout China.
* Rabies is recommended for any traveler who may come in contact with or handle animals, especially dogs. Rabies is common in China while the vaccination is not.
