A TWO-for-one vaccine may offer a cheaper, more effective way to protect against malaria. Biotechnology company GenVec of Gaithersburg, Maryland, modified an adenovirus to express fragments of two proteins called CSP and LSA1, which are normally produced by the malaria parasite Plasmodium falciparum. Once injected into people, the virus should churn out both these antigens, priming the immune system to target the parasite. Tests in mice have shown a vaccine containing the modified virus triggers 5 to 10 per cent of the “killer T” immune cells in mice to recognise and stop the malaria infection,
