Researchers hope antibody studies will pave way for HIV vaccine

HIV Virus in Blood Stream (Shutterstock)The path for a cure or vaccine for HIV is littered with disappointments – much-hyped treatments or trials have ultimately ended in failure.Today, however, the HIV research community is more hopeful, especially in lieu of PrEP – pre-exposure prophylaxis – the use of the antiretroviral drug Truvada to prevent HIV infection.With PrEP, HIV-negative individuals take a daily dose of Truvada to halt HIV transmission, and the drug is more than 99 percent effective at preventing HIV when taken daily.

Broadly neutralizing HIV antibodies pave the way for vaccine

Broadly neutralizing HIV antibodies pave the way for vaccine

HIV infecting a human cell.Credit: NIH A small number of people infected with HIV produce antibodies with an amazing effect: Not only are the antibodies directed against the own virus strain, but also against different sub-types of HIV that circulate worldwide.Researchers from the University of Zurich and University Hospital Zurich now reveal which factors are responsible for the human body forming such broadly neutralizing HIV antibodies, thereby opening new avenues for the development of an HIV vaccine.
