Hi, my son is going to visit friends in Ghana, nr Akkra in March and we wondered if anyone has any tips for the trip. Does he need vaccinations? I thought Malaria might be on the top of the list. Can he drink the water etc. things to avoid....if you live in a country you obviously get used to things there but as a visitor can end up with all sorts of bugs and I think he needs a bit of safe information before he goes. Thanks for any information.
