Abstract

PURPOSE:

The human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome induce account for over 40 million deaths in the past 20 years. Given that the currently available treatments to prevent HIV transmission and disease are not effective in eradicating the virus, vaccination likely represents the only efficacious adapted response to the global impact of this infection. This paper reviews the challenges encountered in the development of an HIV vaccine as well as the different vaccine approaches and main HIV vaccine candidates evaluated in clinical trials.

CURRENT KNOWLEDGE AND KEY POINTS:

In spite the tremendous progress in HIV research, the major challenges that are encountered in the development of an HIV vaccine remain of scientific order and include viral specificities, absence of correlates of immune protection and limitations of existing animal models. Over 30 vaccine candidates have been evaluated in clinical trials. These vaccine approaches include the use of recombinant envelope proteins, DNA vaccines, live-vectored recombinant vaccines, subunit vaccines and prime-boost regimens combining various vaccine candidates. Although the protective efficacy of these candidate vaccines has yet to be demonstrated, some vaccination regiments appear to dampen initial viremia and prolong disease-free survival.

FUTURE PROSPECTS AND PROJECTS:

Faced with the challenges in developing an HIV vaccine, international consortia and new methodologies have been proposed in order to accelerate the development and screening process of new candidate HIV vaccines. Moreover, in the absence of a protective vaccine, the impact of a vaccine that confers partial protection needs to be seriously considered.
