Evaluation of the first malaria vaccine introduction
BACKGROUND: Cameroon is the first country to introduce malaria vaccine (MV) into routine immunisation, following the pilot programme. The vaccine was introduced in 42 health districts across all 10 regions, with plans to scale up in additional districts in future. A mini-postintroduction evaluation (mini-PIE) was conducted to rapidly review the MV programme, make improvements and inform future strategies. METHODS: A programme evaluation was condu…
Seroprevalence of Sars-CoV-2 in Tanzania
Between August and October 2021, before the Omicron wave and before COVID-19 vaccines became widely available in Tanzania, two studies estimated that half of the population in Zanzibar and Mwanza in Tanzania had SARS-CoV-2 antibodies. From May 2020 to Dec 2021, Tanzania adopted a very different COVID-19 mitigation strategy with no lockdowns or quarantines and limited community-level COVID-19 testing. We conducted population-based SARS-CoV-2 serop…
Building confidence in crises – the roles of Sierra Leonean religious leaders’ during the 2014–2016 Ebola outbreak
BACKGROUND: Religious leaders have been involved in health promotion campaigns for many years across West Africa, such as their engagement in the HIV/AIDS pandemic response. This involvement in public health campaigns has indicated varied results in the past and therefore a critical approach is required when engaging them in the outbreak response. Little is known about religious leaders' perceptions of their role in communicating Ebola risks duri…
A qualitative study of academic bullying among junior doctors in Sierra Leone
Academic bullying at USLTHC is systemic, culturally rationalised, and exacerbated by resource constraints. Embedding enforceable anti-bullying policies, structured faculty-development, and accessible mental-health services is essential to protect trainees and protect Sierra Leone's evolving health-workforce
HIV risk behaviour, viraemia, and transmission across HIV cascade stages including low-level viremia
As antiretroviral treatment (ART) coverage for people living with HIV (PLHIV) increases, HIV programmes require up-to-date information about evolving HIV risk behaviour and transmission risk, including those with low-level viremia (LLV; >50 to ≤1000 copies/mL), to guide prevention priorities. We aimed to assess differences in sexual risk behaviours, distribution of viral load (VL) and proportion of transmission across PLHIV subgroups. We analysed…
Ebola vaccine uptake and attitudes among healthcare workers in North Kivu, Democratic Republic of the Congo, 2021
Introduction: During the 2018-2020 Ebola virus disease (EVD) outbreak in the eastern part of the Democratic Republic of the Congo (DRC), prevention and control measures, such as Ebola vaccination were challenging by community mistrust. We aimed to understand perceptions regarding Ebola vaccination and identify determinants of Ebola vaccine uptake among HCWs. Methods: In March 2021, we conducted a cross-sectional survey among 438 HCWs from 100 ran…
The role of community pharmacies in early detection of suspected Covid-19 cases in 2020
Tanzania reported its first COVID-19 case on 16 March 2020. We conducted event-based surveillance of COVID-19 suspect cases among pharmacy clients presenting with respiratory symptoms and influenza-like illness to increase early and rapid detection of COVID-19 cases and mitigate transmission. We conveniently sampled 103 pharmacies from Dar es Salaam, the epicentre for the COVID-19 pandemic in Tanzania at the time. Between 23 April 2020 and 18 May…
Public perceptions of Ebola vaccines and confidence in health services to treat Ebola, malaria, and tuberculosis
Uganda used Ebola vaccines as part of its preparedness and response during the 2018–2020 10 th Ebola virus disease (EVD) outbreak in neighboring Democratic Republic of the Congo (DRC). We evaluated the public’s perceptions of Ebola vaccines and compared their confidence in health services to treat Ebola versus malaria and tuberculosis as part of a survey on Ebola knowledge, attitudes, and practices (KAP) conducted in March 2020. A cross-sectional…
RTS,S/AS01 malaria vaccine pilot implementation in western Kenya
Caregivers in this study believed the RTS,S/AS01 to be effective and were motivated to have their children vaccinated. Despite these positive perceptions of the malaria vaccine, uptake was substantially hindered by persistent health system constraints. Negative provider attitudes emerged as a powerful deterrent to attending immunisation services and hampered uptake of the vaccine. Strategies that focus on improving interpersonal communication ski…
Drivers of Covid-19 policy stringency in 175 countries and territories
Background: New data on COVID-19 may influence the stringency of containment policies, but these potential effect are not understood. We aimed to understand the associations of new COVID-19 cases and deaths with policy stringency globally and regionally. Methods: We modelled the marginal effects of new COVID-19 cases and deaths on policy stringency (scored 0-100) in 175 countries and territories, adjusting for gross domestic product (GDP) per cap…
Association of community engagement with vaccination confidence and uptake
Background: The 2014-2016 Ebola epidemic disrupted childhood immunization in Sierra Leone, Liberia, and Guinea. After the epidemic, the Government of Sierra Leone prioritized community engagement to increase vaccination confidence and uptake. To support these efforts, we examined potential drivers of vaccination confidence and uptake in Sierra Leone. Methods: We conducted a population-based household survey with primary caregivers of children in …
Community Health Workers' Experiences in Strengthening the Uptake of Childhood Immunization and Malaria Prevention Services in Urban Sierra Leone
Introduction: Community health workers (CHWs) play an integral role in Sierra Leone's health systems strengthening efforts. Our goal was to understand CHWs' experiences of providing immunization and malaria prevention services in urban settings and explore opportunities to optimize their contributions to these services. Methods: In 2018, we conducted an exploratory qualitative assessment in the Western Area Urban district, which covers most of th…
Debunking highly prevalent health misinformation using audio dramas delivered by WhatsApp
INTRODUCTION: Infectious disease misinformation is widespread and poses challenges to disease control. There is limited evidence on how to effectively counter health misinformation in a community setting, particularly in low-income regions, and unsettled scientific debate about whether misinformation should be directly discussed and debunked, or implicitly countered by providing scientifically correct information. METHODS: The Contagious Misinfor…
Behaviour adoption approaches during public health emergencies
Human behaviour will continue to play an important role as the world grapples with public health threats. In this paper, we draw from the emerging evidence on behaviour adoption during diverse public health emergencies to develop a framework that contextualises behaviour adoption vis-à-vis a combination of top-down, intermediary and bottom-up approaches. Using the COVID-19 pandemic as a case study, we operationalise the contextual framework to de…
Using immunisation caregiver journey interviews to understand and optimise vaccination uptake
Quantitative and qualitative assessments have revealed diverse factors that influence the uptake of childhood immunisation services and shed light on reasons for vaccination delays and refusals. UNICEF and partner organisations developed the Immunisation Caregiver Journey Framework as a novel way to understand caregiver experiences in accessing and receiving immunisation services for children. This framework aims to help immunisation programmes i…

Barriers to maternal health services during the Ebola outbreak in three West African countries
INTRODUCTION: The Ebola virus disease (EVD) outbreak in West Africa, affecting Guinea, Liberia and Sierra Leone from 2014 to 2016, was a substantial public health crisis with health impacts extending past EVD itself. Access to maternal health services (MHS) was disrupted during the epidemic, with reductions in antenatal care, facility-based deliveries and postnatal care. We aimed to identify and describe barriers related to the uptake and provisi…
Homecare for sick family members while waiting for medical help during the 2014-2015 Ebola outbreak in Sierra Leone
INTRODUCTION: Caring for an Ebola patient is a known risk factor for disease transmission. In Sierra Leone during the outbreak in 2014/2015, isolation of patients in specialised facilities was not always immediately available and caring for a relative at home was sometimes the only alternative. This study sought to assess population-level protective caregiving intentions, to understand how families cared for their sick and to explore perceived ba…
Community engagement in outbreak response
Documentation of structured community engagement initiatives and real-time monitoring of community engagement activities during large-scale epidemics is limited. To inform such initiatives, this paper analyses the Community Led Ebola Action (CLEA) approach implemented through the Social Mobilization Action Consortium (SMAC) during the 2014–2016 Ebola epidemic in Sierra Leone. The SMAC initiative consisted of a network of 2466 community mobilisers…
Integrated digital system for community engagement and community-based surveillance during the 2014–2016 Ebola outbreak in Sierra Leone
Community engagement and community-based surveillance are essential components of responding to infectious disease outbreaks, but real-time data reporting remains a challenge. In the 2014–2016 Ebola outbreak in Sierra Leone, the Social Mobilisation Action Consortium was formed to scale-up structured, data-driven community engagement. The consortium became operational across all 14 districts and supported an expansive network of 2500 community mob…
Access, demand, and utilization of childhood immunization services
BACKGROUND: Urban childhood immunization programs face unique challenges in access, utilization, and demand due to frequent population movement between and within localities, sprawling informal settlements, and population heterogeneity. We conducted a cross-sectional household survey in the Western Area Urban district, Sierra Leone, stratified by slums and non-slums as defined by the United Nations Development Program. METHODS: Based on data from…
Risk perception during the 2014–2015 Ebola outbreak in Sierra Leone
Our results illustrate the complexity of how individuals perceived their Ebola acquisition risk based on the way they received information, what they knew about Ebola, and actions they took to protect themselves. Community-level information sources may help to align the public's perceived risk with their actual epidemiological risk. As part of global health security efforts, increased investments are needed for community-level engagements that al…
