  • Bridging immunization gaps

    Open AccessMoses Mwale, Penelope Masumbu et al.ARTICLEFrontiers in Public Health2025

    Zambia’s 2024 Measles-Rubella Supplementary Immunization Activity (SIA), conducted from 23 to 28 September across all 116 districts, targeted children aged 9–59 months to address immunization gaps exacerbated by COVID-19 disruptions and responding to ongoing measles outbreaks. This community case study evaluates the effectiveness of microplanning, the feasibility of real-time digital monitoring, and the equity of reaching zero-dose children durin…

  • Comparing and integrating human mobility data sources for measles transmission modeling in Zambia

    Open AccessNatalya Kostandova, Christine Prosperi et al.ARTICLEPLOS Global Public Health2025

    Quantifying population mobility is crucial in developing accurate models of infectious disease dynamics. Increasingly, multiple data sources are available to describe individual and population mobility in a single location; however, there are no methods to systematically integrate these data. Combining information from these data sets may be valuable and help mitigate inherent biases in each data set due to sampling, censoring, and recall. We exa…

  • High measles and rubella vaccine coverage and seroprevalence among Zambian children participating in a measles and rubella supplementary immunization activity

    Open AccessChristine Prosperi, Shaun Truelove et al.ARTICLEPLOS Global Public Health2025

    Post-campaign coverage surveys estimate the proportion of previously unvaccinated children vaccinated during supplementary immunization activities (SIA) but cannot address whether susceptible children seronegative to measles and rubella viruses were vaccinated during the SIA. We conducted a cross-sectional serosurvey nested within the November 2020 measles-rubella SIA in Zambia, systematically sampling children aged 9 months to 5 years at 30 SIA …

  • Community of Communities

    Open AccessTeresa E Leslie, Yu Bin et al.ARTICLEProgress in community health…2025

    Introduction: This paper describes and evaluates the COVAX educational program for Vaccine Acceptance and Access Lives in Unity, Engagement, and Education, Baltimore's vaccine peer ambassador (VPA) initiative, which served to engage the community (including those resistant to vaccination) and increase community knowledge of COVID-19 and COVID-19 vaccination. Methods: A mixed methods approach was used to describe the effectiveness of the education…

  • Feasibility and acceptability of collecting dried blood spots (DBS) from children after vaccination during supplementary immunization activities to estimate measles and rubella seroprevalence

    Open AccessAndrea C Carcelen, Christine Prosperi et al.ARTICLEPLOS Global Public Health2024

    Nested serosurveys within routine service delivery platforms such as planned supplemental immunization activities (SIAs) provide an opportunity to collect information that can be used to answer valuable questions on the effectiveness and efficiency of the delivery model to inform future activities. However, integrating research data collection in SIAs is rarely done due to concerns it will negatively impact the program. We conducted a serosurvey …

  • Who is missed in a community-based survey

    Open AccessNatalya Kostandova, Simon Mutembo et al.ARTICLEPLOS Global Public Health2024

    Community-based serological studies are increasingly relied upon to measure disease burden, identify population immunity gaps, and guide control and elimination strategies; however, there is little understanding of the potential for and impact of sampling biases on outcomes of interest. As part of efforts to quantify measles immunity gaps in Zambia, a community-based serological survey using stratified multi-stage cluster sampling approach was co…

  • An evaluation of the early impact of the Covid-19 pandemic on Zambia’s routine immunization program

    Open AccessAmy K Winter, Saki Takahashi et al.ARTICLEPLOS Global Public Health2023

    Implications of the COVID-19 pandemic for both populations and healthcare systems are vast. In addition to morbidity and mortality from COVID-19, the pandemic also disrupted local health systems, including reductions or delays in routine vaccination services and catch-up vaccination campaigns. These disruptions could lead to outbreaks of other infectious diseases that result in an additional burden of disease and strain on the healthcare system. …
