The situation is improving slowly, but only in a few ways. It used to be the case that both the mainstream of islam and extremists were against vaccination (and even now the mainstream is wary of it : apparently it proves allah doesn't have power, and of course the disease and it's effects is the fault of the vaccine, not a major flaw of allah).
But extremists are as much against polio vaccination as ever. Apparently they're going to defeat the world with "muslim wombs" and polio vaccination is apparently really a secret plot to make them infertile. (in a way it is of course : more surviving children will extinguish one of the main reasons for having many children, and if it happens the same as in the west in the 20th century, number of children will drop by a lot)
