Mode of action of adjuvants: Implications for vaccine safety and design

Abstract

For decades, the search for new vaccine adjuvants has been largely empirical. A series of new adjuvants and related formulations are now emerging that are acting through identified immunological mechanisms. Understanding adjuvant mechanism of action is crucial for vaccine design, since this allows for directing immune responses towards efficacious disease-specific effector mechanisms and appropriate memory. It is also of great importance to build new paradigms for assessing adjuvant safety at development stages and at regulatory level. This report reflects the conclusions of a group of scientists from academia, regulatory agencies and industry who attended a conference, organized by the Inte..
