After reading the previous posts regarding vaccinations in Vietnam, I still decided to have my booster for typhoid. I've had this shot before, and I had it given to me last 2 years ago.
This morning I went into the Columbia Asia clinic/hospital in HCMC and the doctor told me that a booster is only needed every 3 years. The yellow vaccination card I have says every 2 years (for a one-time shot). When I got it in Mexico last time, the woman told me every 2 years, as well. The doctor this morning then showed me the info paper that comes with the bottle for the shot and it said every 3 years.
I've just looked on the net and 1 site said every 3 years, one site said every 2 unless recommended differently from the vaccine producer, the CDC says every 2, etc.
Does anyone want to weigh in on this? What have you been told, what have you done? I don't have medical ins. and therefore don't need to get sick if I can prevent it (no comments needed on this, please). I'll go back Monday unless several of you can tell me otherwise.
