Laser makes vaccines seven times more effective

The first tests done on animals show an increased efficiency up to seven times. In this case, the researchers refer to vaccines and concluded that there were four to seven times more antibodies to be produced when lit up the skin with a laser, in the face of what happened when you used the laser.

The laser has a role similar to other chemical helpers, as aluminium salts and oils, which are used to make the vaccine more effective. In the study published in Nature Communications, researchers do not reveal what the expected effectiveness in flu vaccine, but will expect an increase in their effectiveness.

The laser creates microtermais areas on the skin, which end up self-regeneration. Upon being formed these areas of breakage, dying cells send "danger signals" and ask the body that sends immune cells to respond to viruses and other invaders. The body reacts sent defense cells that help recognize the threat and react. The lasers used in the study had been designed for cosmetic purposes and make your skin younger.

For now, the recognised side effects are smaller than those that can arise when using chemical helpers to increase the effectiveness of vaccines.
