Stimulation of protective and cross-protective immunity against influenza B virus after adjuvant mucosal immunization of mice.
Intratracheal immunization of mice with inactivated influenza B virus and delipidated Bacillus firmus as adjuvant increases protection of mice against infection with the homologous virus strain and induces cross-protection: mice immunized by influenza virus B/Yamanashi 166/98 were protected even against phylogenetically distant virus drift variant B/Lee/40 lethal for mice.
