Vaccines have long been used to combat infectious diseases, however the last decade has witnessed a revolution in the approach to vaccine design and development. No longer is there a need to rely on the laborious classical methods, such as attenuation or killing the pathogen. Now, sophisticated technologies - such as genomics, proteomics, functional genomics, and synthetic chemistry - can be used for the rational identification of antigens, the synthesis of complex glycans, the generation of engineered carrier proteins, and much more. Never has research in this area been more exciting. In...
