Advances in antibody-based hiv-1 vaccines development

Despite the great success of antiretroviral therapy, both in the treatment and prevention of HIV-1 infection, a vaccine is still urgently needed to end the epidemic. According to UNAIDS, in 2018, about 35% of HIV-1 infected persons did not receive antiretroviral therapy (ART), resulting in 1.7 million new infections in that year. One major reason for actual HIV-1 transmissions is the fact that about 20% of HIV- 1 infected persons do not know about their HIV-positive status and therefore are not on ART despite the potential high viral load linked to high risk of virus transmission. Therefore, in particular in countries with high HIV incidence, a preventive vaccine is required to reduce HIV transmissions in the general population. In this special issue of Vaccines, invited experts contribute a series of articles to the current understanding of antibody-based HIV-1 vaccine development. ..
