Developing an effective HIV vaccine is achievable, as shown by the RV144 trial. Lessons learned accelerate progress toward a safe and effective vaccine, crucial for ending the epidemic.
Area of Science:
- Immunology
- Vaccinology
- Public Health
Background:
- Recent advances in pre-exposure prophylaxis (PrEP) raise questions about the continued need for an HIV vaccine.
- The RV144 trial demonstrated partial efficacy, suggesting that an effective HIV vaccine is possible.
Purpose of the Study:
- To review lessons learned from HIV vaccine efficacy trials, including RV144.
- To highlight current HIV vaccine concepts in clinical development.
- To emphasize the role of HIV vaccines in controlling the epidemic.
Main Methods:
- Review of findings from the RV144 trial and other HIV vaccine efficacy studies.
- Analysis of immune correlates from the RV144 trial.
- Overview of HIV vaccine candidates in clinical development.
Main Results:
- The RV144 trial provided crucial data on HIV vaccine efficacy and assessment methods.
- Immune correlates analysis from RV144 offers guidance for future vaccine design.
- HIV vaccine research has yielded valuable lessons for accelerating development.
Conclusions:
- An effective HIV vaccine is achievable and essential for ending the HIV epidemic.
- Lessons from efficacy trials are guiding the development of safer and more effective vaccines.
- HIV vaccines, alongside other prevention strategies, are vital tools for epidemic control.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
