Can be a lifelong resistance of influenza virus vaccines for universal

[] Message: United Kingdom scientist recently developed a universal vaccine, this vaccine can make in your life from winter resistant influenza to bird flu all influenza. Usually the validity period of the vaccine now use only a year because of virus variants too fast. This universal vaccine called FLU-v vaccine, it's worse than a traditional vaccine easier production, so you can reserve up to deal with the major infectious diseases.

Every year, over two thousand people die from influenza United Kingdom, most of them are elderly people. Avian influenza, the expert called sooner or later in a human pandemic, only in the United Kingdom had seized the 70 million lives. It is hoped that the universal vaccine for human testing can start next year, if the proceeds smoothly, and three to the vaccine will be able to enter the market.

Buckingham County PepTcell company developed vaccine Stuart · Dr. Robinson said: "We hope that once or twice a week and they understand it, you can bring a lifetime of immunity. "Pre-existing vaccine to focus on the virus surface some protein, protein variations, advance prevention often each new variant is almost impossible. Universal vaccine based on other parts of the protein, this part of the proteins are viruses all variants have in common, there have been 60 years has not been variation. Universal vaccine depends on is called cytotoxic T cells of the immune system and not kill virus antibodies.

Test indicates that no vaccine inoculation FLU-V died some NIH usually can kill their viruses, this results in the Toulon Toronto Conference today show: most of them are vaccinated mouse successful survival and unvaccinated mice have died.

By changing the mouse gene, these rodents have and human immune system is similar, it is possible these vaccines will also play in the human body to the same effect. FLU-v vaccine can mass rapid production, traditional vaccines in eggs in culture, it was a slow process, an egg can only produce one injection quantity.

A universal vaccine are researchers of the "Holy Grail", is a potential wealth. At least two other company British-based Acambis and the Swiss research firm Cytos are such vaccines. Some experts also commented on this, Professor Emeritus of the University of Aberdeen · Pan Hugh Pennington said: we do need a new vaccine, it will focus on the variants of the virus in the vaccine responded quickly.

But reading University of filtration of pathogens and scholar Ian · Jones warned that the principle of similarity-based HIV vaccine development have failed, T cells can kill infected cells, but not necessarily to prevent virus infection. Warwick University Professor Malcolm said this vaccine and General vaccine compared to faster kill the virus, but a new kind of virus, it may only be a short-term prevention approach.
