Abstract
Attenuated stable influenza type B virus strains are obtained by recombining a vaccinal and previously attenuated influenza type B virus strain with an influenza type B virus isolate having the desired serotype and isolating a recombinant having at least one marker property of the attenuated parent strain which is not shared by the other parent strain and the antigenic composition of the other parent strain. The obtained strains are useful for the production of nasal influenza vaccines.
