The problem i see with hepA is that it is more easily transmitted than other things. It is fecal-oral. So if someone goes to the toilet, doesn't wash their hands properly and prepares your food and they have HepA, there is a chance you will get it. DH had his vacc before going to Thailand and i had mine when traveling to Fiji, but the kids were too little. DD1 had it before we moved to PNG, but DD2 was still too little. I will get DD2 vaccinated in due time, but when she's a little bit older. We are in a position where i buy, wash and cook all our own food so our risk isn't as high as if we were eating out a lot. Having said that hygiene in this place is terrible so our risk would still be quite high.

My reasoning against the vacc is that is generally a treatable disease. There are fatalities but with access to proper medical care they are rare.
