In a daring experiment in Europe, scientists used mosquitoes as flying needles to deliver a "vaccine" of live malaria parasites through their bites. The results were astounding: Everyone in the vaccine group acquired immunity to malaria; everyone in a non-vaccinated comparison group did not, and developed malaria when exposed to the parasites later.

love the back to earth method tho!
This is such a brilliant idea. If only this worked on AIDS.
It's a bit sci-fi, but if it could be done, i think the cure/vaccine would spread to more people and more quickly than medical personel could distribute it.
