Scientists are developing painless needle-free vaccination – Technology – Science and technology

Dutch researchers are developing laser technology that allows “virtually painless” vaccination without the use of a conventional syringe.

According to the researchers, it will be a groundbreaking invention that will alleviate the fear of needles and attract more people to be vaccinated. Apparatus similar toy guns uses a laser to push small droplets through the outer layer of the skin.

The mechanism was described by David Fernandez Rivas, a professor at the University of the Dutch region of Twent and a researcher at the Massachusetts Institute of Technology (MIT).

According to him, the process is faster than mosquito bites and should not cause any pain, because it does not affect the nerve endings in the skin. “The glass containing the liquid is heated by a laser for milliseconds, a bubble is formed in the liquid which expels the liquid at a speed of at least 100 kilometers per hour. This allows us to penetrate the skin without damaging it. No wound or entry point can be seen, “he added.

Fernandez Rivas expects that the invention will help attract more people to vaccinate, prevent the risk of contamination from dirty needles and reduce the amount of medical waste.

The researchers used a European Union grant of 1.5 million euros to test the device on tissue samples. Now it is time to apply for funding for human testing. According to Fernandez Rivas, it can take about one to three years for the method to be available to the general public.

According to the therapist, about one in a thousand people needs a repeated therapeutic session to prepare for the planned injection.
