Could mos­qui­toes de­liver malaria vac­cines

BBC Earth (Asia) - - Science -

Un­for­tu­nately, there is no vac­cine against malaria, de­spite decades of in­tense re­search and de­vel­op­ment. More than 20 po­ten­tial malaria vac­cines are in their trial phases though, which aim to ef­fi­ciently elim­i­nate cer­tain stages of the life cy­cle of Plas­mod­ium

– the malaria-caus­ing par­a­site that some mos­qui­toes carry and in­ad­ver­tently in­fect us with. There has been a proof-of-con­cept study that shows mos­qui­toes could de­liver a can­di­date vac­cine through their saliva, but how much they de­liver de­pends on how many times they bite some­one, so de­liv­er­ing the right dose of a vac­cine would be in­cred­i­bly chal­leng­ing.
