Variations in COVID-19 vaccine hesitancy over time: a serial cross-sectional study in five West African countries.

Objectives: This study aims to identify the factors influencing vaccine hesitancy, willingness and its variation over time in order to inform more responsive strategies for increasing vaccination uptake. The specific objectives are: (1) to describe and compare levels of COVID-19 vaccine hesitancy among the general population in rural and urban settings in West Africa over time and (2) to identify factors associated with COVID-19 vaccination willingness and hesitancy among the general population across five West African countries over time.

Design: Following a baseline survey (Wave I), three serial cross-sectional surveys (Waves II-IV) were implemented.

Responding to fluctuations in public and community trust and health seeking behaviour during the COVID-19 pandemic: a qualitative study of national decision-makers' perspectives in Guinea and Sierra Leone.

Background: The level of trust in health systems is often in flux during public health emergencies and presents challenges in providing adequate health services and preventing the spread of disease. Experiences during previous epidemics has shown that lack of trust can impact the continuity of essential health services and response efforts. Guinea and Sierra Leone were greatly challenged by a lack of trust in the system during the Ebola epidemic.

Caregiver acceptance of malaria vaccination for children under 5 years of age and associated factors: cross-sectional household survey, Guinea and Sierra Leone, 2022.

Background: Malaria is a leading cause of death and reduced life span in Guinea and Sierra Leone, where plans for rolling out the malaria vaccine for children are being made. There is little evidence about caregiver acceptance rates to guide roll-out policies. To inform future vaccine implementation planning, this analysis aimed to assess potential malaria vaccine acceptance by caregivers and identify factors associated with acceptance in Guinea and Sierra Leone.

Design: Cross-sectional survey carried out between 5 May and 5 June 2021.

Participants And Setting: 4198 individuals from urban and rural settings in Burkina Faso, Guinea, Mali, Senegal and Sierra Leone participated in the survey.
