This is how Covid-19 ended with a strain of flu and that will change the next vaccines. "It has been the final nail in the coffin of the B/Yamagata lineage of influenza," says Raúl Ortiz de Lejarazu, director emeritus of the National Influenza Center of Valladolid.

The WHO already considers this strain offlu extinct, along with two lineages A and another B in order to have the widest possible coverage against this respiratory virus.
