  • Contextualizing future maternal RSV vaccination acceptance and trust among pregnant and lactating women in Kenya

    Open Access•Molly Sauer, Berhaun Fesshaye et al.•ARTICLE•PLOS Global Public Health•2025

    Maternal vaccination, or vaccination in pregnancy, offers a critical opportunity to provide protection to pregnant women and simultaneously confer passive immunity to infants in the first months of life, when infections are particularly serious and their immune systems are still developing. Respiratory syncytial virus (RSV) is one such serious infectious disease for newborns, but a newly approved and recommended vaccine for respiratory syncytial …

  • Trust in healthcare providers, information sources, and concerns for new maternal vaccines among pregnant and lactating women in Kenya

    Open Access•Jessica L Schue, Berhaun Fesshaye et al.•ARTICLE•PLOS Global Public Health•2025

    New maternal vaccines have the potential to reduce morbidity and mortality for infants from common illnesses that pose the greatest risk in the earliest phase of their life. Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infections among infants under six months of age. With the recent approval of a maternal vaccine for RSV, this study aimed to understand decision-making factors among pregnant and lactating women …

  • The impact of 10-valent pneumococcal conjugate vaccine on the incidence of admissions to hospital with hypoxaemic and non-hypoxaemic pneumonia in Kenyan children

    Open Access•Ilsa L Haeusler, Eunice Wangeci Kagucia et al.•ARTICLE•PLOS Global Public Health•2025

    Observational evidence suggests that pneumococcal conjugate vaccines (PCVs) are more effective at reducing the incidence of hypoxaemic pneumonia compared to non-hypoxaemic pneumonia. We examined the impact of 10-valent PCV (PCV10, Synflorix) on hypoxaemic pneumonia hospital admissions using data from an existing PCV impact study of clinical and radiographic pneumonia. PCV10 was introduced, with catch-up among children under 5 years, in the Kilifi…

  • The cost of care for children hospitalized with respiratory syncytial virus (RSV) associated lower respiratory infection in Kenya

    Open Access•Joyce U Nyiro, Bryan O Nyawanda et al.•ARTICLE•BMC Public Health•2024

    RSV-associated disease among young children leads to a substantial economic burden to both families and the health system in Kenya. This burden may differ between Counties in Kenya and similar multi-site studies are advised to support cost-effectiveness analyses

  • Implications of gestational age at antenatal care attendance on the successful implementation of a maternal respiratory syncytial virus (RSV) vaccine program in coastal Kenya

    Open Access•Joyce U Nyiro, Elizabeth A Bukusi et al.•ARTICLE•BMC Public Health•2020

    In a random sample of pregnant women from Kilifi HDSS, Coastal Kenya with card-confirmed ANC clinic attendance, 76.6% would be reached for maternal RSV vaccination within the gestational age window of 28-32 weeks. Widening the vaccination window (26-33 weeks) or (24-36 weeks) would not dramatically increase vaccine coverage and would require consideration of antibody kinetics data that could affect vaccine efficacy
