Currently China does not require the tourists from major western countries immunizations. However, it is subject to change at any time. Please check with your tour agent or the consulates of China at home to ascertain if China requires proof of any inoculation. It is the tourists' sole responsibility for compliance with vaccination and other health requirements of Chinese government. For those planning to go to Tibet, please consult a physician before making the trip. Visitors with respiratory or cardiac problems should avoid such high altitudes.
