I have had all of my necessary injections apart from Hep B. I'm going to be working in a school with small children so it has been recommended that I have it as it is likely that they will fall and cut themselves etc. I leave in a month and I can either do a rapid course of injections or have the first 2 before I leave and another whilst I'm there. I was just wondering how easy it would be to obtain my third injection whilst I'm in argentina?
