I don't remember having an anti malarial injection prior to being sent out to Aden. I'm not sure that one was available.
In Borneo, a few years earlier, we had to take a vile tasting little yellow pill called Paludrine every morning. This wasn't part of the routine in Aden, though, so maybe the risk wasn't that high.
Snakes? Quite a few up country (Al Habilayn/Radfan) but they mostly left us alone unless we antagonized them.
