A similar effect was observed after the transfer of CD4+T-cells obtained from FLU-NA-DIII vaccinated mice (P<0.05; Figure 4C and D), whereas the transfer of FLU-NA-DIII immune CD8+T cells did not confer any protection against disease caused by infection with WNV-NY99 (Figure 4E and F). The gene discussed is CD4; the disease is infection.
