Researchers are working to find a flu vaccine taking advantage of the immune system of the flame, according to a study published in Science. And the vaccine that is being worked does not help one year, but every year. Through the blend of human and flame antibodies, a vaccine was created that provided lasting protection against two strains of influenza A and B. The experiment has been successfully tested in rats infected with lethal doses of influenza viruses.
In theory, the technique could possibly be used to make a nasal spray that would function as a so-called universal vaccine, providing long-term protection against all types of flu.
