Reporte del congreso Mecanismos inmunológicos de la vacunación; diciembre 13-18 de 2012, Ottawa, Canadá

The conference Immunological Mechanisms of Vaccination of the Keystone Symposia was held on December 13-18, 2012, in Ottawa, Canada. There were more than 400 participants from all over the world in the fi eld of immunology and vaccine research. During fi ve days, attendees had the possibility to present and discuss their current work and also to encourage new collaborations. Fifty-fi ve oral presentations were grouped in seven sessions according to the following topics: Innate sensing of pathogens and vaccines, Augmenting immune response to vaccines, T and B cell memory to vaccines, Understanding signatures of vaccine protective effi cacy, Translating immunity to vaccines and Vaccines against global threats. Additionally, more than 240 posters were presented and two workshops on Novel adjuvants and Vaccine delivery were organized. The quality of the papers presented at this conference shows that there is a global concern in eradicating chronic and re-emerging infectious diseases. Currently, a special attention is focused to the search for new and potent adjuvants and delivery systems that allows the generation of the immune response at the systemic and mucosal compartments to increase vaccine effi cacy.
