I have many things to say about your response, but I realize you have made up your mind about vaccinating your children and will respectfully refrain.
However, the quoted statement offends me - I would argue that many people in East Africa take malaria quite seriously. It is responsible for the deaths of 655,000 people a year, mostly children under 5 in sub-Saharan Africa. The impact on national economies is considerable, with high incidence countries facing a loss in potential economic growth of 1.3% annually compared to low incidence countries with similar characteristics. I appreciate that you have personal experience in the region, but feel that it is unseemly that you dismiss such a major cause of morbidity, mortality, and economic losses offhand.
I agree. It's true that just about everyone in Kenya (my scope of experience) comes down with "a touch of malaria" like people in the US come down with an annoying cold or mild case of flu. Those are the adults who didn't die from it when they were babies and children. There is also a high rate of chronic anemia in East Africa that is at least in part due to endemic malaria.
Embassy housing doesn't mean living in a bubble, either.
