Volunteers get bit to test new strategy for malaria vaccine

WASHINGTON (AP) — Researchers infected lab mosquitoes with genetically weakened malaria parasites, and then recruited volunteers willing to be bitten — a lot — to test a possible new strategy for a vaccine.
The idea: Vaccinate using living malaria parasites that are too weak to make people sick. It’s a huge challenge, and while Wednesday’s study is a small step, it illustrates the urgent quest for a powerful malaria vaccine.
