Do the Microbiota Influence Vaccines and Protective Immunity to Pathogens? Engaging Our Endogenous Adjuvants.

Overview

The reliance of the immune system on constitutive microbial stimulation support the idea that both responsiveness to vaccines and vaccine design need to be considered in the context of host-microbiota interactions. Manipulation of microbe function or composition via diet alteration or microbiota engraftment may soon become a viable approach to control immunity and, as such, vaccine responses. Learning from our endogenous original adjuvants could be critical in overcoming the enormous hurdle of vaccine design against the numerous pathogens that cause chronic infection. Going forward, rationally designed vaccines that take advantage of the inherent adjuvant properties of the microbiota could have a major impact on the prevention of disease.
