While the hope of a COVID-19 vaccine is at the forefront of everyone’s minds, some positive news related to needle vaccines has re-surfaced – that painful needles could be a thing of the past. According to a UC Berkeley study, “a self-administered vaccine using a needleless, pill-sized technology that jet-releases a stream of vaccine inside the mouth” is in the works, and it’s called the MucoJet.
Not administered on people but demonstrated through technology, the study showed that the MucoJet could deliver vaccine-sized molecules to immune cells in the mouths of animals. This technology could catapult oral vaccine delivery and boost immunity in the mouth’s buccal region of cells, where many infections enter the body.

A patient holds the MucoJet against the inside of his/her cheek and the device releases a jet stream that directly aims toward the buccal region, which is “rich in immune cells but underutilized in immunology.” The Mucojet stores vaccines in powder form and could allow for vaccine delivery to remote locations in the future.
