Outline of Final Research Achievements

Recently, pertussis is known as one of re-emerging infectious diseases. One of main reasons is that current pertussis vaccine cannot fully induce cell-mediated immunity which is important for elimination of Bordetella pertussis infection. Current pertussis vaccine contains aluminum salt (alum) as a vaccine adjuvant, but alum is known to mainly induce humoral immunity and, to weakly activate cell-mediated immunity. To improve pertussis vaccine, selection of adequate vaccine adjuvant must be required. Receltly, we found that the combination of CpG ODN and STING agonist functions as vaccine adjuvant and synergistically induces Th1-type cellular immunity. In this study, we investigate the development of novel pertussis vaccine using CpG+STING agonist combination adjuvant.
