Mice infected with influenza virus develop cytotoxic T lymphocytes (CTL) specific for viral antigens prior to the appearance of virus-specific antibody-forming cells (AFCs). Effector T cells were detected at a time coincident with a precipitous decline in pulmonary virus titer. CTLs of draining lymph nodes and spleen were found to be cross-reactive among H-2 compatible cells infected with influenza type A virus subtypes. AFCs were observed to be primarily hemagglutinin specific. Virus-specific IgA-secreting AFCs were detected in mediastinal lymph nodes of infected mice.
