Scientists from Oxford University have developed a method of ultrasound vaccination that does not require injections, writes gazeta.ru with reference to Reedus.

The technique involves mixing the vaccine with tiny proteins that form bubbles under the influence of ultrasound. These bubbles penetrate the upper layers of the skin and burst, releasing the vaccine.

Researchers tested the technique on mice and found it to be effective and safe. When using ultrasound vaccination, mice produced much more antibodies than with traditional injection vaccination, while their skin remained intact.

However, scientists are not yet sure how the bubbles under human skin will behave. The team behind the technology has already begun developing ways to track the vaccination process in people.
