A family of broadly neutralizing antibodies from a chronically infected donor provides a schematic for designing vaccines and treatments that target multiple strains of the virus.

A synthetic antibody prevents infection in four monkeys injected with heavy doses of the virus.

Researchers track the evolution of HIV in a single patient to understand what drives the production of broadly neutralizing antibodies.

In mutating to evade immune detection, HIV becomes susceptible to detection by different antibodies, suggesting new strategies for vaccination.
