It's worse than you think...there IS no malaria vaccine. I'm sort of curious as to what your friend got. The only preventative is to take
prophylactic anti-malarials and use a lot of DEET. Usually you get Lariam, which is mefloquine, although there are some other ones they mix it up with
these days in order to keep the local malarial strains from becoming resistant.
Malaria isn't caused by a virus or bacterium, it's a protozoan. It has to be passed in blood, so you can get it from a transfusion or if a
blood-sucking insect bites an infected person and then you, typically a mosquito.
edit: spelling error
Oh, and ps, it also takes time to manifest malarial symptoms after you actually ARE infected, the malarial life cycle in a human is really
complicated; it passes through several life stages in your liver and blood cells.
SOME malaria can hit you right away, but it can take months.
Usually you run a low-grade fever, a bad headache, loss of energy, pain in the kidneys and get the malarial shakes, sometimes jaundice. It's
generally not like what you described.
