Multilevel mechanisms of HIV acquisition in young South African women
We focus on three under-examined thematic areas which cross-cut multiple levels of influence and that our research and the literature suggest are critical to shaping young women’s HIV risk—gender inequity, schooling and socio-economic status, and emotional well-being. Understanding how these determinants shape risk and protection is critical to developing effective interventions to reduce new HIV infection.

A multidimensional digital approach to address vaccine hesitancy and increase COVID-19 vaccine uptake among African American young adults in the South
Despite being a key “super-spreader” population transmitting SARS-Co-V2, the causative agent of COVID-19 (COVID), acceptance of COVID vaccination is lowest among African American and young adult populations. A digital health intervention has the potential to increase the reach and uptake of COVID vaccination among African American young adults which is central to ending the pandemic.
