I am planning a 3 month trip to southeast asia beginning in mid-January. Specifically, I plan to visit Thailand, Cambodia, and Vietnam.

I checked on the cdc website and they recommended Hepatitis A and B vaccinations prior to going to this region. These vaccinations a given in a series of 3 shots over the course of 5 months. The problem is that I only have a couple months before my trip.

How important is it to get these vaccinations? Should I delay my trip?

Any comments appreciated.

Thank you.

There's an "accelerated" program for Hepatitis (both A and B; they're often combined together in one shot ("twinrex" is what it was called for me; don't know if that's a brand name or what)), which will still give you full protection during your trip.
I had this, and got the following:
day 1: Hep A+B
day 30: Hep B
day 60: Hep A+B
day 90: leave
day 240: Hep A+B (not essential, but getting this shot will extend the protection to 25 years and lifelong respectively, so it's totally worth it)

From what I've heard from others, the schedule can be even more accelerated than that, too.

Also, for a three month trip to SE Asia you should definitely get both, imo. But talk to a doctor for this.

Thanks Sander, that helps alot. I will investigate the 'accelerated' program.

In addition to torque's question, what other vaccinations are recommended for Vietnam and Cambodia? We are going for just over a month, leaving at the end of December. I have a doctor's appointment booked, but was wanting some information before I go, so I at least know what the doctor is talking about!

So far I have been recommended: yellow fever, diphtheria, hep A and B, Japanese encephalitis, tetanus, typhoid and TB. Are all these essential? It's not a problem if they are, but I'm not really keen on having all these injections if they are not really necessary.

Thanks in advance,

Hi Soliqa,

I was directed to the CDC website on Thailand which can be found here:

Midway down the page is a list of "Vaccine-Preventable Diseases", but I believe everything that's there is already in your list.

Have a great trip!

Yellow Fever Vaccine is definitely NOT needed in SE Asia ( The YF virus is endemic in parts of Africa and S America, NOT Asia) and would only be needed if you were coming FROM a YF endemic zone.

I also rarely recommend JE vaccine to most travelers on typical backpacker trips- This may be ocnsidered for a quite prolonged trip, where you are staying for extended times in rural areas, camping out etc..., but generally this is a low risk for typical travelers ( I have traveled twice to SEA, for a total of about 6 months and decided against JE and rabies vaccines).

The others on your list are a good idea- typhoid, Hepatitis A, and be up to date on Tetanus/ pertussis/ diphtheria. By TB , you may be refering to BCG- this too is NOT recommended for most travelers- unless you are volunteering, or worring in a hospital/ HIV clinic etc...

Have fun...
