Developed by the American biotech company Sanaria , this new vaccine builds on the long - established cognition that mosquito bites can actually protect against malaria , supply those mosquito have first been weakened using radiation . The only catch is that it would take a thousand mosquito bites for someone to actually develop existent immunity to malaria , which has made the practical use of that knowledge pretty minimal .
The musical theme behind this vaccine campaigner , which has the tricky name PfSPZ , is to progress up a population of laboratory - rise mosquito , irradiate them , and then excerpt the now weakened malaria sponge contained within . Those sponger can then be inject into the bloodstream . In an other clinical trial , 40 volunteers received vary United States Department of State , while 17 receive a placebo . When these 57 antecedently healthy player were exposed to the real malaria parasite , all became infected expect for members of the group that received the in high spirits potential dose . Of those 15 participants , 12 successfully press off the infection , suggesting the vaccine really does have some potential to fight off malaria , even if it is very early days .
Talking to BBC News , Dr. Robert Seder from the Vaccine Research Center at the National Institutes of Health abide by :
“ We were frantic and thrilled by the result , but it is important that we repeat it , extend it and do it in larger phone number … base on the history , we knew dose was significant because you needed 1,000 mosquito bites to get security – this validate that . It allow us in future study to increase the Zen and falsify the agenda of the vaccine to further optimise it . The next decisive questions will be whether the vaccine is durable over a long menstruation of time and can the vaccine protect against other strains of malaria . ”
