Abstract
During the past 20 years, the development of HIV vaccines has come a long way. The focus has progressively changed from the traditional protein-based HIV vaccines that induce humoral immunity to the live recombinant viral vector-based HIV vaccines capable of eliciting both cellular and humoral immune responses. These new viral vector-based vaccines encoding multiple HIV antigens, delivered either alone or in heterologous prime-boost modalities elicited antigen-specific CTL responses in immunized hosts and protected animals from disease. The viral vector-based vaccines have proven to be potent vaccines in pre-clinical studies and foster the hope to put an end to the ever-increasing threat of the AIDS epidemic. Several unique features of viral vector-based HIV vaccines have contributed to their success, including their intrinsic immune-modulating properties, high transduction efficiency, and in vivo production of immunogens within the cell mimicking a natural infection without the associated health risks. In this review, we will discuss the characteristics of non-replicating viral vectors most commonly used for HIV vaccines with a particular focus on immune responses elicited by the vector particles alone and their effect on the potency of viral vector-based HIV vaccines.

Management of HIV: Management of HIV: old challenges and new needs
The aim of this thematic issue is to provide the most recent updates regarding the effective management of HIV infection. Antiretroviral therapy (ART) has significantly decreased HIV-related mortality, leading to an enhancement in the quality of life and life expectancy for people living with HIV (PLWH). Despite the numerous advancements ...read more
