Vaccines against Emerging Diseases (Ebola/Zika/Dengue/Chik)

Vaccine induced immunity that is established in advance of virus infection relies primarily on adaptive immune responses for protective efficacy. Critically, vaccination depends on the properties of antigen recognition, activation, expansion, memory, trafficking and the multitude of specialist functions of lymphocytes. The extent to which vaccine induced immunity is successful also determines the spread and maintenance of a viral pathogen within a population. Viral vaccines have had profound and enduring consequences for human and animal health; the worldwide eradication of smallpox and rinderpest are testament to their outstanding contribution to modern society.
