A promising vaccine under development by Sanaria has some malaria strains running scared. The PfSPZ vaccine was shown to not only protect 64% of subjects from contracting the strain of malaria the treatment was developed from, the vaccine also protected 5 of the 6 subjects treated and exposed to a different strain. Sorry subject #6! Oh, and it does all this while affording eight months of protection at >90% efficacy, which no malaria vaccine to date has been able to do. It’s currently in Phase I, though it has been given fast track designation, so if it can survive the arduous clinical trials process it could be a very important tool in the fight to eradicate malaria.
