I'm heading to south east asia for a couple of months in may-june and doing a round trip through thailand vietnam and cambodia and was wondering what vaccinations people who have been regard as necessary? we'll probably be doing a bit of trekking in Chiang Mai and Sapa and spending a bit of time exploring angkor wat, halong bay and southern thailand beaches. apart from that probably gonna stick to the towns and cities. Have been recommended to get rabbis and Hep B aswell as malaria vaccinations but the all add up to about £300. i dont mind paying this if they're neccessary but dont want to throw money away. will definetly get the malaria one but as i'm travelling with my girlfriend i will unlikely be having any sexual contact with locals so is the Hep B vaccination necessary, and also the Rabbis?
any help would be great
With Hep B it's not only through sexual contact you may come into the presence of Hep B. If you have an injury and require a blood transfusion, the blood may not have been screened for Hep B.
You can get a shot that combines Hep A & Hep B (it's called Twinrex here, not sure if that is just a brand name though), and we were recommended that before going to SE Asia. As mojorob said, you don't get Hep B just through sexual contact.
Also recommend that you are up to date with your tetanus injections, and we also had a typhoid injection before we went. Didn't worry about the rabies one though. We took malaria tablets while we were in Cambodia but not in Vietnam (we were hesitant to take them because they made some people we were travelling with really sick, but when my friend and I started taking them in preparation for Cambodia they had no bad effect on us at all).
Cheers for the advice guys.
My logic for the Hep B vaccination is i've never needed a blood transfusion before and if i were to need one and the blood hasn't been screened then i'm probably at a pretty big risk of HIV anyway and Hep B is probably least of my worries. I was thinking it more likely to need the rabbis vacine as its more likely an animal to bite or lick me while trekking around and rabbis is pretty much fatal without vaccination. Is this sound logic or a bit stupid?
I agree with soliqa-
Strongly recommended are hepatitis A and typhoid vaccines and a booster on your tetanus/polio if it is not up to date.
As a general health promotion Hep vaccine B is advised, regardless of your travel. i agree your travel per se is not a huge risk for Hep B, but you really would be best to be vaccinated anyways....
Malaria is not a shot but pills as noted above- it is certainly recommended in certain areas- including more rural areas of your trip and Cambodia.
Rabies is actually low risk for most travelers- The vaccine given by itself before exposure does not completely prevent rabies- you still would need post-exposure shots, but you would need 2 more shots "only" on days 0 and 3. If you had never been vaccinated before exposure, then you would need shots at 0, 3, 7, 14 and 28 plus rabies immune globulin. So either way you would need to seek medical care.
Plus this is an exposure readily avoidable. For most typical backpackers, rabies pre-exposure vaccine is not needed, and just avoid dogs....
