U.S.A. develops " A stitch becomes effective " Rabies vaccine
Washington, September 18 (Xinhuanet) after being bitten by the dog, people will all inject vaccine of rabies. But vaccine of rabies injects 5 stitches before and after needing at present, troublesome and costly. American researchers develop a kind of rabies vaccine newly, only need a stitch and offer immune protection effectively, it is valid to already test on experiment mouse and primate at present.
The researchers from Thomas and Jefferson university say on a new American " infectious disease magazine " on the 18th, what the rabies vaccine that they developed used is rabies and virus alive, but rejected a very key gene of the virus - -M The gene, make the virus unable to duplicate oneself.
This kind of vaccine injection is after human, the virus will bring out the strong immunoreaction which deals with rabies rapidly, and meanwhile because of lacking M gene, the virus is unable to duplicate spreading in the body, so will not cause a disease.
By contrast, rabies vaccine injected at present, that was used is to lose active rabies and virus. Generally implement the vaccine injection after may be infected with rabies and virus, need to successively divide 5 stitches to inject, some also need to inject a stitch of rabies and immunoglobulin (Ig) afterwards.
Researchers introduce, utilize rabies vaccine that virus alive made into, can bring out the immunoreaction strong enough, so it is enough to offer immune protection to inject a stitch. In addition, according to present experiment, it is valid that this kind of vaccine is injected before or after being exposed to rabies and virus.
According to statistical data that research group offer, annual whole world have about 4 Wan die of rabies to 7 people Wan. Especially in some developing country, after being bitten by the dog because of economy or time people, unable to insist on it after hitting 5 stitches of rabies vaccine at all, it causes the death that final disease is sent.
