Future vaccines : new needs, new concepts, new approaches, what vaccine paradigm for the ^21st century ?

The sixth lecture was originally intended to deal with the infectious causes of cancer, but given the length and complexity of the chosen theme of immunosubversion by pathogens, I preferred to change the theme of this last lecture and, to remain within the context of the host-pathogen relationship seen from the angle of the immune response, I gave a lecture on vaccination. The basic idea was: how can we counter the subversive strategies of pathogenic bacteria and viruses against the immune system by developing new vaccines? Hence the title of the lecture: "Vaccines of the future: new needs, new concepts, new approaches, what vaccine paradigm for the ^21st century?"
