Most vaccines get injected into muscle,swallowed by mouth,or squirted into the nose.But in a clinical study reported in January 2025 in Nature Medicine[1],researchers in the Netherlands used a less conventional method to deliver an investigational vaccine:mosquito bites.The mosquitoes carried malaria-causing Plasmod-ium falciparum parasites that had been genetically engineered to trigger a productive immune response without making people sick.Nine of ten study participants who each,in a single session,with-stood 50 bites from this laboratory strain of mosquitoes,success-fully fended off infection when challenged with infective malaria parasites six weeks later.
