Abstract Background A subset of the virus-specific CD8 cytotoxic T lymphocytes CTL isolated from the lungs of mice infected with human respiratory syncytial virus RSV is impaired in the ability to secrete interferon Y IFNy a measure of functionality. It was suggested that the impairment specifically suppressed the host cellular immune response a finding that could help explain the ability of RSV to re-infect throughout life. Results To determine whether this effect is dependent on the virus the route of infection or the type of infection respiratory disseminated or localized dermal we compared the CTL responses in mice following intranasal IN infection with RSV or influenza virus or IN or intradermal ID infection with vaccinia virus expressing an RSV CTL antigen. The impairment was .
