Abstract:	The development of HIV prophylactic vaccines is facing an impasse, since all phase IIb/III clinical trials were halted in 2023 without demonstrating efficacy. Thus, the field is in need of developing novel immunogens and vaccination strategies that induce broadly neutralising antibodies together with potent Fc-dependent effector functions, as well as protective cross-reactive CD4 and CD8 T cell responses. Nucleic acid vaccines, particularly mRNA vaccines, have been one of the major groundbreaking advances in the current decade. Nucleic acid vaccines may help recalibrate the HIV vaccine field towards the use of delivery systems that allow the proper expression of immunogens as a sole antigen (i. e. , membrane-bound trimeric envelope glycoproteins) or even to be displayed in a multiantigen platform that will be synthesised by the host. In this review, we will summarise how the multiple HIV vaccine strategies pursued in the last 40 years of HIV research have driven current vaccine development, which are the most relevant immunogens identified so far to induce balanced adaptive immune responses, and how they can benefit from the acceptance of nucleic acid vaccines in the market by reducing the limitations of previous delivery systems. The incorporation of nucleic acid vaccines into the current heterogeneous repertoire of vaccine platforms may represent an invaluable opportunity to reignite the fight against HIV.
