Scientists develop microjet device for needle-free vaccine delivery

Researchers from the University of California Berkeley have developed a needle-free delivery device for vaccines. The team published their work in Science Translational Medicine. 

The MucoJet device is a pill that releases its cargo in a microjet when pressed up against the cheek. The pressure generated from pushing the device against the cheek is enough to force large molecules through the patient’s mucosal layer and into tissue concentrated with immune cells.
