Scientists from Oxford University have developed a needle-free vaccination method. In this respect reports “Reedus,” referring to the results of the study. It was announced that the team mixed the molecules of the injected drug with tiny proteins that deliver the vaccine to the upper layers of the skin using ultrasound.
This technique has already been tested on mice, where they were exposed to ultrasound for one and a half minutes. The vaccine penetrated the upper layers of the skin, where proteins caused drug-filled blisters to form. The bubbles then burst and released the mixture.
Scientists found that although the new method delivered 700 times fewer vaccine molecules, the mice produced significantly more antibodies than the injection method. However, the animals showed no signs of pain and their skin remained intact.
For the team, it is not yet clear how the bubbles under human skin will behave: whether the vaccine molecules will be released in the required quantities and how uniform this process will be. But the developers of the methodology have already begun to create ways to follow this process.
