Oxford University scientists have made a great innovation.
Publika.az The Russian mass media reports that Oxford University scientists have developed a needle-free method of vaccination. “Ridus” publication published information on this based on the results of the research.
According to the information, the researchers mixed the molecules of the solution ready for injection with small proteins that transport the vaccine to the upper layer of the skin with the help of ultrasound.
The method has already been tested on mice, which were exposed to ultrasound for one and a half minutes. The vaccine penetrated the upper layer of the skin, where the proteins caused blisters filled with the drug to form. Then the blisters burst and the solution got under the skin.
The scientists found that although 700 times less vaccine molecules were injected under the skin through the new method, the mice’s body produced more antibodies compared to the injection method. At this time, they did not feel pain, and their skin remained undamaged.
Scientists have not yet determined how these bubbles behave under human skin. The question that worries them is whether the vaccine will flow under the skin in the right amount and how long this process will last. But researchers are already working on ways to fully control this process.
