Report says that the vaccine cuts risk of malaria in half for children 5-17 months for one year.
How significant is this test result? Shouldn't a vaccine be almost %100 effective, as with vaccines for polio and MMR? Does this indicate that more work needs to be done? Or can a vaccine that is 50% effective still be sold? I realize that 50% is a lot better than not at all, but I can't imagine a vaccine being marketed in the US that is only 50% effective. Maybe Africa is different.
It's all we've got. Been a long time coming. Bill and Melinda Gates have pumped in Billions to get us this far. It's 50% for the toughest Malaria. 90% for the easier forms. The next thing is in the works but it involved this vaccine and something else as a booster. But, that version is 3-4 years behind this one.
