Malaria: You do not need on this itinerary. There is no malaria in any of these cities, and in October there will be few to zero mosquitoes around anyway.

Measles: You should have been vaccinated for this as a kid (or if old enough, had the natural disease)--either way, should be immune.

Tetanus: Everybody, everywhere should be up-to-date on this whether they travel or not. If you have not had an initial injection series or a booster in last 10 years, get it. Diptheria (often given in combo w/Tet) and Polio should be kept similar status--check your records and/or ask your doctor.

Hepatitis A: Get it. High risk of this in China due to water and food handling issues. As a matter of fact, I advise getting this even if you live in a developed country in N. America, Europe, etc. You no longer need to travel to the 3rd World, the 3rd World food and food handling has come to you. Note: this is given as a series so get started right away. Even if you can't finish the series before the trip, the initial shot gives you some protection. Do finish the series after the trip. Finishing the entire series is considered to give you lifelong protection, so you won't need to repeat it in the future.

Hep B: For most non-resident foreigners not engaging in risky behaviors and not working in the medical/relief field, not needed. But be aware a large % (some places 20%) of population in China and some other Asian countries has either active disease or carrier status. If you get into an accident and need blood.... Don't put this at the top of the priority list, but if you have the cash and can get, it is a good series to have and is considered lifetime protection. (USA kids are now getting Hep B as part of their childhood series.) There is a combined Hep A + Hep B vaccine (Twinrix) that you can ask about, if you want both.

Regular Flu: Get the regular annual seasonal flu shot ASAP, whether travelling or not. It's easy to pick this up just by being in airport crowds, on a plane, or in public areas/crowds in China.

H1N1 flu: is not currently available in the US but will be sometime in October maybe. This is a new vaccine and the safety profile across large mass of people is still unclear. I personally would not go out of my way to try to source this and get before international travel, just in case there are untoward side effects. Note: China has rolled out its own version as of now for parts of the Chinese population esp kids, but they do not require it for international travellers entering China. And don't get any vaccination in China itself.

Typhoid: Not on your list, and I wouldn't make it your top priority, but useful for travel to Asia. Typhoid disease is uncommon in the northern Chinese major cities you are going to (even in the natives), but more common in the south and in SE Asia and Indian subcont. Two forms: single injection, or oral 4-capsule series. Protection for 2-5 years depending on type of vaccine then you have to get again. If time and/or cash is short, skip it for this trip.

Much of the injection prep you may need for this trip, you won't need to repeat again for future international travel so it gets simpler/quicker/cheaper. Above all, don't get paranoid about health when travelling in China. It's relatively easier to stay healthier here than in most of SE Asia or India, for instance. Just use common sense, wash hands a lot, and watch what you put in your mouth to eat and drink.
