A new vaccine approach that delivers a 'double punch' could give the immune system an edge against malaria, AIDS and other infectious diseases, according to a new study.

A team of US and UK-based researchers injected human volunteers with the malaria parasite's DNA, followed by a boost with a modified poxvirus that can produce parasite proteins.

They report in Nature Medicine that neither the parasite's DNA nor the poxvirus alone evoked a strong immune response. But the combination tricked the volunteers' immune systems into producing enough immune cells to attack malaria. Success against malaria raises hope for other diseases too, they say.
