  • The not talking is actually what kills you’– young South African women’s communication barriers about sexual health

    Open Access•Felicity Hartley, Jill Trappler et al.•ARTICLE•Culture Health & Sexuality•2026

    Conversations about sex and sexual health are often stigmatised and shaped by socio-cultural influences. For young women, lack of adequate communication can influence access to information, knowledge and behaviour and therefore increase vulnerability to negative outcomes such as sexually transmitted infections (STIs) and unintended pregnancy. This qualitative study investigated the barriers young women face when seeking dialogue about sex, their …

  • Neutralizing antibody responses over time in a demographically and clinically diverse cohort of individuals recovered from Sars-CoV-2 acquisition in Africa

    Open Access•Nonhlanhla N Mkhize, Shuying Sue Li et al.•ARTICLE•PLOS Global Public Health•2025

    COVID-19 has affected millions worldwide. Research characterized immune responses of individuals who acquired SARS-CoV-2 and identified co-factors, such as HIV, associated with greater likelihood of poor clinical outcomes. SARS-CoV-2-specific neutralizing antibodies (nAbs) are a strong correlate of protection but their elicitation in people living with HIV (PLWH), and particularly in southern Africa, is less well characterized. HVTN 405/HPTN 1901…

  • Alvac-prime and monomeric gp120 protein boost induces distinct HIV-1 specific humoral and cellular responses compared with adenovirus-prime and trimeric gp140 protein boost

    Open Access•Leigh H Fisher, Erica Lazarus et al.•ARTICLE•PLOS Global Public Health•2025

    Although clade-specific and cross-clade mosaic prime–boost HIV-1 vaccine regimens were advanced to the HVTN 702 and HVTN 705 efficacy trials, neither regimen prevented HIV acquisition. The respective Phase 1/2a studies, HVTN 100 (NCT02404311) and HVTN 117/HPX2004 (NCT02788045), provided rich immunological data, including previously identified correlates of risk, for comparing immune responses elicited by these vaccine regimens over time. We analy…

  • Safety and immunogenicity of booster vaccination and fractional dosing with Ad26.COV2.S or BNT162b2 in Ad26.COV2.S-vaccinated participants

    Open Access•Catherine Riou, Jinal N Bhiman et al.•ARTICLE•PLOS Global Public Health•2024

    We report the safety and immunogenicity of fractional and full dose Ad26.COV2.S and BNT162b2 in an open label phase 2 trial of participants previously vaccinated with a single dose of Ad26.COV2.S, with 91.4% showing evidence of previous SARS-CoV-2 infection. A total of 286 adults (with or without HIV) were enrolled >4 months after an Ad26.COV2.S prime and randomized 1:1:1:1 to receive either a full or half-dose booster of Ad26.COV2.S or BNT162b2 …

  • Safety, effectiveness and immunogenicity of heterologous mRNA-1273 boost after prime with Ad26.COV2.S among healthcare workers in South Africa

    Open Access•Nigel Garrett, Tarylee Reddy et al.•ARTICLE•PLOS Global Public Health•2024

    Limited studies have been conducted on the safety and effectiveness of heterologous COVID-19 vaccine boosting in lower income settings, especially those with high-HIV prevalence., The Sisonke Heterologous mRNA-1273 boost after prime with Ad26.COV2.S (SHERPA) trial evaluated a mRNA-1273 boost after Ad26.COV2.S priming in South Africa. SHERPA was a single-arm, open-label, phase 3 study nested in the Sisonke implementation trial of 500000 healthcare…
