Canadian and American scientists have found a way to protect the humans from all flu strains with a universal vaccine.
To ensure a lifetime of immunity will be sufficient to inoculate once.
According to who, the annual flu epidemics cause 3 to 5 million cases of severe illness, and the number of deaths reaches 250-500 thousand. Vaccination is the only method of specific prophylaxis of influenza. The vaccine composition is updated every year because the virus constantly mutates and forms new ones.
Experts from McMaster University (Canada), Medical school Icahn at mount Sinai and the University of Chicago (USA) in a joint study discovered a new class of antibodies capable of neutralizing the most dangerous types of flu virus.
Part of the flu virus is always recognizable – even when it mutates and changes. New antibodies can train the immune system to find and destroy these fragments unchanged. The revolutionary design will pave the way for the creation of a universal vaccine that will provide life-long protection against influenza after a single injection.
