Developing an HIV-1 vaccine that can elicit antibodies to prevent infection has been a formidable challenge. Although no single immunogen has generated antibodies that can neutralize diverse isolates, progress has been made in understanding () the structure of the HIV-1 envelope glycoprotein, which is targeted by neutralizing antibodies, () how HIV-1 evades antibodies made by an infected host, and () how rare monoclonal antibodies can exhibit broadly neutralizing activity. Advances in structural and molecular biology coupled with new approaches to isolate neutralizing antibodies from HIV-1-infected individuals are enhancing our understanding of what humoral immune responses will be required for a vaccine. This review summarizes progress in understanding the host antibody response to HIV-1 and current strategies for applying this information to develop an effective vaccine.
