Mosaic HIV-1 vaccine regimen in southern African women (Imbokodo/HVTN 705/HPX2008): a randomised, double-blind, placebo-controlled, phase 2b trial

Background: HIV type 1 (HIV-1) remains a global health concern, with the greatest burden in sub-Saharan Africa. Despite 40 years of research, no vaccine candidate has shown durable and protective efficacy against HIV-1 acquisition. Although pre-exposure prophylaxis in groups with high vulnerability can b...

Regulatory T cell abundance and activation status before and after priming with HIVIS-DNA and boosting with MVA-HIV/rgp140/GLA-AF may impact the magnitude of the vaccine-induced immune responses

Immunobiol., Suppl; 223 (12), 2018
Little is known about regulatory CD4 T cells (Tregs) in the context of HIV vaccines. Tregs can be differentiated into resting (FoxP3+CD45RA+ - rTregs), activated (FoxP3HighCD45RA- - aTregs) and memory (FoxP3LowCD45RA- - mTregs). Tregs, as CD4 T cells, are also frequent targets for HIV infection. We studi...

Optimizing the immunogenicity of HIV primeboost DNA-MVA-rgp140/GLA vaccines in a phase II randomized factorial trial design

PLOS ONE; 13 (6), 2018
Although there has been a decline in the number of new human immunodeficiency virus (HIV) infections over the years, millions of people continue to be exposed and infected [1]. More than 200 HIV vaccine phase I and II, and 6 efficacy trials have been conducted [2, 3]. The RV144 Thai trial is the only tri...

Intradermal HIV-1 DNA immunization using needle-free zetajet injection followed by HIV-modified Vaccinia virus ankara vaccination is safe and immunogenic in Mozambican young adults: A Phase i randomized controlled trial

AIDS res. hum. retrovir; 34 (2), 2018
According to UNAIDS, there were a total of 36.7 million people living with HIV and 2.1 million new infections in 2015. Eastern and Southern Africa continues to be most severely affected, accounting for 51.7% of the total global infections. Antiretroviral therapy has contributed to slowing the HIV epidemi...

Recent progress in immune-based interventions to prevent HIV-1 transmission to children

J. int. aids soc; 20 (4), 2017
Globally, 150,000 new paediatric human immunodeficiency virus type 1 (HIV-1) infections occurred in 2015. There remain complex challenges to the global elimination of paediatric HIV-1 infection. Thus, for the global community to achieve elimination of new paediatric HIV-1 infections, innovative approache...
