Wuhan scientists invent a new type of vaccine that can "smear" the nose to fight the flu
On the 12th, the reporter learned from the Chinese Academy of Sciences Wuhan virus, Cui Zongqiang researcher, Chen Jianjun, associate researcher successfully developed a new broad-spectrum anti-influenza virus mucosal nano vaccine. When interviewed by reporters, Cui Zongqiang said that vaccination is the most effective way to prevent influenza. However, there are many subtypes of influenza virus, and the mutation is fast. The existing inactivated vaccine needs to be updated every year for the changes of the epidemic strain, and it is urgent to develop a "wide-spectrum influenza vaccine". Cui Zongqiang introduced that they use the influenza virus conservative antigen M2e, combined with nanotechnology to prepare a cross-protection influenza vaccine, and it is expected to develop a broad-spectrum anti-influenza vaccine in the future. The mice immunized with the nano-vaccine are currently verified to be completely resistant to the lethal infection of the H1N1 virus and also to the lethal infection of the bird flu virus H9N2. It is understood that the vaccine is administered through the nasal cavity to avoid muscle damage caused by the injection route, and no adjuvant is added during the immunization. The use process is safer and more convenient. How do you do it through the nasal cavity? In the Hollywood blockbuster "Infectious Diseases," people who get the vaccine can be immunized by spraying them into the nasal cavity. Cui Zongqiang introduced that the vaccine is still in the laboratory research stage and has already applied for a patent. It will take a while to enter the market.
