AB - Current influenza vaccines are effective but imperfect, failing to cover against emerging strains of virus and requiring seasonaladministration to protect against new strains. A key step to improving influenza vaccines is to improve our understanding ofvaccine induced protection. Whilst it is clear that antibodies play a protective role, vaccine induced CD8+ T cells can improveprotection. To further explore the role of CD8+ T cells we used a DNA vaccine that encodes antigen dimerised to an immune celltargeting module. Immunising CB6F1 mice with the DNA vaccine in a heterologous prime boost regime with the seasonal proteinvaccine improved the resolution of influenza disease compared to protein alone. This improved disease resolution was dependenton CD8+ T cells. However, DNA vaccine regimes that induced CD8+ T cells alone were not protective and did not boost theprotection provided by protein. The MHC targeting module used was an anti-I-Ed single chain antibody specific to the BALB/c strainof mice. To test the role of MHC targeting we compared the response between BALB/c, C57BL/6 mice and an F1 cross of the twostrains (CB6F1). BALB/c mice were protected, C57BL/6 were not and the F1 had an intermediate phenotype; showing that thetargeting of antigen is important in the response. Based on these findings, and in agreement with other studies using differentvaccines, we conclude that in addition to antibody, inducing a protective CD8 response is important in future influenza vaccines.
