Jet injectors were designed to deliver vaccines without needles, using high-pressure liquid to penetrate the skin. They enabled rapid mass immunizations in the 1960s, but multi-use designs allowed blood backflow, leading to disease transmission. Modern single-use versions exist, but traditional needles remain safer, cheaper, and more practical. #MedicalHistory #Vaccines #Science #Medicine #PublicHealth #Innovation | Facts Wiki
