Ideal adjuvants for enhanced vaccine efficacy: Innate immune activation; A blessing or a curse?
3rd International Conference on Vaccines & Vaccination

Keynote: J Vaccines Vaccin

Abstract:

H ighly purified antigens suffer from poor immunogenicity. Current paradigms suggest the way to address this problem is with adjuvants based on potent innate immune activators, thereby mimicking natural infection. The key question is whether vaccine immunogenicity and reactogenicity are inseparable? Are pro-inflammatory danger signals really needed to make modern vaccines effective? Using examples of vaccines against influenza, West Nile virus, Japanese encephalitis virus and other important biodefense pathogens, data will be provided to show that bigger is not always better when it comes to vaccine adjuvants, thereby explaining how adjuvants such as delta inulin (Advax?) with more subtle immune effects may surprisingly provide the best long-term immune memory responses and vaccine protection.
