Setback for Malaria Vaccine: Time for an AMC?

There was bad news in research published yesterday in the New England Journal of Medicine about the effectiveness of what had seemed to be the best prospect for a malaria vaccine, known by the unsexy name of 'RTS,S'.

The study of the phase III trials finds that in babies (aged 6-12 weeks) the vaccine only reduces malaria by less than a third. This is disappointing because this is less than half the effectiveness that had been suggested by the phase II clinical trials.
