Vaccine Against All Mosquito Borne Diseases

I was watching a news report on Al Jazeera about a Cambodian lab that believes they can make a vaccine to prevent all mosquito borne diseases being passed by mosquitoes. They believe the answer is in the mosquitoes' saliva. What do you think, feasible?

Diseases Borne Mosquito All Vaccine

Hmm, since a vaccine works by carrying an antigen (Or a marker) of a certain disease that when injected on you, instead of causing the disease (Since it usually is inactivated or just a piece of the virus) it gets known by your immune system so it can produce antibodies against it. So, their premise is if the mosquito's saliva become the antigen, the antibodies formed against it would quickly act as soon as the mosquito bites and transfers the vaccine along with the virus. The question I guess is would the antibody attached to the saliva being an antigen would also help eliminate the virus it carries with it? It would be interesting to see how the study goes.
