Cows injected with a protein that mimics HIV’s envelope make broadly neutralizing antibodies that inhibit multiple strains of the virus.

Researchers identify aspects of the patient, the virus, and the infection itself that influence whether a person with HIV will produce broadly neutralizing antibodies.

Infusing anti-HIV antibodies provides macaques with protection against infection for up to six months, according to a study.

From diagnostics to vaccines, llama antibodies point to new directions in HIV research.

Recent discoveries are spurring a renaissance in HIV vaccine research and development.

Delivering antibodies to HIV-infected people can lower levels of the virus, a study shows.
