Many countries require inoculation against certain diseases to enter the country. China does not require proof of vaccinations to enter the country.
That doesn’t mean you shouldn’t look into some preventative healthcare. However, 4 to 6 weeks before you visit China, the CDC recommends the following vaccinations: measles-mumps-rubella (MMR) vaccine, diphtheria-tetanus-pertussis vaccine, varicella (chickenpox) vaccine, polio vaccine, and your yearly flu shot. The CDC recommends all travelers are up to date on routine vaccines before every trip.
2 More Vaccinations to Consider
The CDC also recommends getting vaccinated against Hepatitis A as the tap water in most of China is not safe to drink, and you can contact Hep A through contaminated water or food prepared in contaminated water. Also if you’re an adventurous eater or staying in a rural area, you should get a current vaccination to guard against typhoid.
Why Get Vaccinated 4-6 Weeks Before Travel?
It takes time for a vaccination to build up in your immune system to fully protect you. Therefore, several weeks lead time will give you the maximum protection while traveling.
