The path toward an HIV-1 vaccine.

HIV is responsible for millions of deaths around the world and in the absence of available treatment capable of a cure, only the vaccine can offer protection against this virus. However, and after three decades of research, such a vaccine remains elusive. Here, I attempt to explain the major challenges on the development of an anti-HIV immunogen, and how the three-dimensional pictures of antibodies interacting with this virus can guide us to the design of a successful vaccine.
