The "The Daily Telegraph" website reported on November 6th that the universal influenza vaccine does not need to be vaccinated every year.
Scientists have developed a vaccine that can withstand all flu viruses for a lifetime and can dispense with the flu vaccination every winter.
The study found that this new type of universal influenza vaccine can effectively defend against many different types of influenza viruses, including the deadly bird flu and H1N1 influenza viruses. The researchers said that the vaccine only need to be vaccinated once.
Influenza viruses are prone to change, so elderly and pregnant women who are susceptible to the flu are currently being vaccinated each year to ensure that they are protected.
Small-scale clinical trials of this new vaccine, called Flu-V, show that it can significantly reduce the chance of infection and reduce the severity of symptoms.
Scientists engaged in this research are planning to conduct large-scale clinical trials and hope to obtain a vaccine that can be widely used after five to ten years.
Professor John Oaksford, a virologist at the Royal London Hospital, said: "The vaccine has obvious biological effects and deserves further study, especially in the scope of its immune response. In the 2009 H1N1 flu epidemic, there were several After the vaccine was developed in a month later, the universal vaccine made it possible for people not to wait and to eliminate the need for annual vaccination against seasonal influenza."
Vaccination works by training the immune system so that it can recognize the virus and increase its resistance to the virus, but the flu virus constantly changes its “coatâ€, which means that it can escape the discovery of the immune system.
However, with this new universal vaccine, scientists are able to identify a key part of the virus that is buried deep inside the virus, this part will not change, and it is present in any kind of virus.
By training the body's immune system, any infection caused by the flu virus will be detected by the immune system and resisted. (Text/Xinhua)
