From the reading I have done, it seems that all travellers should make sure their routine vaccinations are up to date, such as:

Diptheria

Tetanus

Polio

 

Most travellers should also look to get the following for travel to Vietnam:

Hepatitis A

Typhoid

 

Some pages also say that you could have, the following, but I know that they were not advised for a local friend in London and I tend to think that some of these sites just list them all so that they are covered. I personally will not be getting these ones:

 

Hepatitis B

Rabies

Cholera

Japanese Encephalitis

 

In a lot of the blogs that I have read and my personal advice would be that you don’t need Malaria tablets for the area’s we are going to in Vietnam and I would suggest the same with Cambodia.

 

Everyone has different levels of Risk and so you should always check with your local health or Travel Clinic and they will advise you the best course of action.
