| Outline of Final Research Achievements |
All current vaccines were investigated in mouse model. Inflammatory nodules spread into muscle bundle space without the degeneration and atrophic changes of muscle cells, which were observed in muscle contracture. Cytokine profiles were examined in muscle tissues after immunization. IL-1β, IL-6, TNF-α, 1L-4, and G-CSF levels increased 3 h after vaccination with Alum-adjuvanted vaccines at the injection sites, and decreased 7days and afterwards.
No significant difference in inflammatory cytokines was observed between the febrile and non-febrile groups, but higher than in normall suubjects. The mean G-CSF level was higher in the febrile group than in non-febrile group.
Inflammatory responses are shown to modulate adaptive immune responses and associate with local reactions as adverse reactions.
