Vaccine adjuvants; the good, the bad and the ugly


4th International Conference on Vaccines & Vaccination

September 24-26, 2014 Valencia Convention Centre, Spain

Nikolai Petrovsky

Keynote: J Vaccines Vaccin

Abstract :

H ighly purified antigens suffer from poor immunogenicity. Current paradigms to address this problem focus onuse ofpotent innate immune activators as adjuvants, thereby mimicking natural infection. Unfortunately using this approach adjuvant immunogenicity and reactogenicity are largely inseparable. This talk will address the question of whether pro-inflammatory danger signals are 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. Novel polysaccharide adjuvants such as delta inulin (Advax?) with more subtle immune effects surprisingly provide the best long-term immune memory responses and vaccine protection in the absence of generation of danger signals
