Malaria kill over a million people a year , mostly in Sub - Saharan Africa where the infected mosquito population is out of command . Now , epidemiologists are germinate a radical unexampled mechanism for vaccinating at - risk of infection populations : through mosquito raciness .
researcher at Radboud University in Nijmegen , the Netherlands , staged a small proof - of - principle experiment , aimed at determining whether pic to parasite , via insect bites , could inoculate humans against malaria .
make love that humans can develop an immunity to malaria after recapitulate exposures and that the drug chloroquine pour down malaria parasites in the late point of infection , the researchers divided 15 guinea pig into two groups . They peril the first group , sporadically , to parasite - bearing mosquitoes and treated them with chloroquine . The 2nd chemical group , the researchers also treated with chloroquine , but did n’t expose to the mosquitoes . All the volunteers stopped taking chloroquine and were subsequently disclose to parasite - carrying mosquito . No penis of the radical previously exposed to malaria developed the disease ; each member of the comparison radical did .
Although it ’s a far yell from delivering an real vaccinum via worm — and seems more a call for widerspread statistical distribution of antimalarial drug — it does present the possibility that insects could someday be used to immunise population against disease . With respect to pandemics like malaria , such a mechanism could be a life ring , but it also presents a wakeless ethical quandary . The bailiwick in this test have their consent to be infected , persons living among vaccinum - carrying critters would n’t have the same sumptuousness .
