Malaria Vaccine Introduction in Cameroon: Early Results 30 Days into Rollout.

Cameroon introduced the malaria vaccine in its routine immunization program on 22 January 2024 in the 42 districts out of 200 that are among the most at risk of malaria. A cross-sectional analysis of the data on key vaccine events in the introduction roadmap and the vaccine uptake during the first 30 days was conducted. In addition to available gray literature related to the introduction of the malaria vaccine, data on the malaria vaccine uptake by vaccination session, collected through a digital platform, were analyzed. A total of 1893 reports were received from 22 January 2024 to 21 February 2024 from 766 health facilities (84% of overall completeness). Two regions out of ten recorded less than 80% completeness. As of 21 February 2024, 13,811 children had received the first dose of the malaria vaccine, including 7124 girls (51.6%) and 6687 boys (48.4%). In total, 36% of the children were vaccinated through outreach sessions, while 61.5% were vaccinated through sessions in fixed posts. The overall monthly immunization coverage with the first dose was 37%. Early results have shown positive attitudes towards and acceptance of malaria vaccines. Suboptimal completeness of data reporting and a low coverage highlight persistent gaps and challenges in the vaccine rollout.

Setting up a data system for monitoring malaria vaccine introduction readiness and uptake in 42 health districts in Cameroon.

Three months after the first shipment of RTS,S1/AS01 vaccines, Cameroon started, on 22 January 2024, to roll out malaria vaccines in 42 districts among the most at risk for malaria. Cameroon adopted and implemented the World Health Organization (WHO) malaria vaccine readiness assessment tool to monitor the implementation of preintroduction activities at the district and national levels. One week before the start of the vaccine rollout, overall readiness was estimated at 89% at a national level with two out of the five components of readiness assessment surpassing 95% of performance (vaccine, cold chain and logistics and training) and three components between 80% and 95% (planning, monitoring and supervision, and advocacy, social mobilisation and communication). 'Vaccine, cold chain and logistics' was the component with the highest number of districts recording below 80% readiness. The South-West and North-West, two regions with a high level of insecurity, were the regions with the highest number of districts that recorded a readiness performance below 80% in the five components. To monitor progress in vaccine rollout daily, Cameroon piloted a system for capturing immunisation data by vaccination session coupled with an interactive dashboard using the R Shiny platform. In addition to displaying data on vaccine uptake, this dashboard allows the generation of the monthly immunisation report for all antigens, ensuring linkage to the regular immunisation data system based on the end-of-month reporting through District Health Information Software 2. Such a hybrid system complies with the malaria vaccine rollout principle of full integration into routine immunisation coupled with strengthened management of operations.

Beyond the numbers: An in-depth look at Cameroon's fifth national COVID-19 vaccination campaign through geographical and gender lenses.

BACKGROUND: Cameroon has been struggling with low Covid-19 vaccination coverage, with only 4.5 % of the population receiving the primary series as of November 2022. The COVID-19 Vaccine Delivery Partnership (CoVDP) conducted a high-level mission to Cameroon to assess progress and advocate for actions to address bottlenecks. The objective of the mission was to administer at least 3,000,000 doses of vaccines during the 5th Mass vaccination campaign. This study examines the factors contributing to the success of the campaign and uses a geographical and gender lens to assess the results. METHODS: The study is a secondary analysis of data from the DHIS2 collected during the 5th mass vaccination campaign for Covid-19. Descriptive statistics were used to assess coverages per location and gender expressed in OR. sccess factors, and chi-squared tests were used to assess differences in vaccine distribution across regions and by gender. RESULTS: This 5th vaccination campaign benefitted from a strong political commitment facilitated by CoVDP's mission, international support, collaboration, planning, supervision, and demand generation. The campaign recorded 2 019 118 administered vaccine doses, a staggering 46-fold increase in vaccinated individuals relative to the first round, with vaccination coverage reaching 10.1 % of the general population. However, the study reveals regional and gender disparities in vaccination coverage. Men had higher odds of being vaccinated than women in the three Sahel regions. Among individuals with comorbidities, the national coverage rate was only 14 %, and the Far North and East regions exhibited the lowest coverage rates. Janssen was the most used vaccine, and the total AEFI cases reported were 2 per 1000 vaccine doses. CONCLUSION: The 5th COVID-19 vaccination campaign in Cameroon saw a strong political commitment and was the most successful so far. Despite the gains, there was gender disparity in coverage in some regions. It is important to continue the established momentum, ensure equitable access in the Sahel regions, and reach high-priority groups with primary series and booster doses.

Factors influencing rapid progress in child health in post-conflict Liberia: a mixed methods country case study on progress in child survival, 2000-2013.

OBJECTIVES: Only 12 countries in the WHO's African region met Millennium Development Goal 4 (MDG 4) to reduce under-five mortality by two-thirds by 2015. Given the variability across the African region, a four-country mixed methods study was undertaken to examine barriers and facilitators of child survival prior to 2015. Liberia was selected for an in-depth case study due to its success in reducing under-five mortality by 73% and thus successfully meeting MDG 4. Liberia's success was particularly notable given the civil war that ended in 2003. We examined some factors contributing to their reductions in under-five mortality. DESIGN: A case study mixed methods approach drawing on data from quantitative indicators, national documents and qualitative interviews was used to describe factors that enabled Liberia to rebuild their maternal, neonatal and child health (MNCH) programmes and reduce under-five mortality following the country's civil war. SETTING: The interviews were conducted in Monrovia (Montserrado County) and the areas in and around Gbarnga, Liberia (Bong County, North Central region). PARTICIPANTS: Key informant interviews were conducted with Ministry of Health officials, donor organisations, community-based organisations involved in MNCH and healthcare workers. Focus group discussions were conducted with women who have experience accessing MNCH services. RESULTS: Three prominent factors contributed to the reduction in under-five mortality: national prioritisation of MNCH after the civil war; implementation of integrated packages of services that expanded access to key interventions and promoted intersectoral collaborations; and use of outreach campaigns, community health workers and trained traditional midwives to expand access to care and improve referrals. CONCLUSIONS: Although Liberia experiences continued challenges related to limited resources, Liberia's effective strategies and rapid progress may provide insights for reducing under-five mortality in other post-conflict settings.

Global implementation survey of Integrated Management of Childhood Illness (IMCI): 20 years on.

OBJECTIVE: To assess the extent to which Integrated Management of Childhood Illness (IMCI) has been adopted and scaled up in countries. SETTING: The 95 countries that participated in the survey are home to 82% of the global under-five population and account for 95% of the 5.9 million deaths that occurred among children less than 5 years of age in 2015; 93 of them are low-income and middle-income countries (LMICs). METHODS: We conducted a cross-sectional self-administered survey. Questionnaires and data analysis focused on (1) giving a general overview of current organisation and financing of IMCI at country level, (2) describing implementation of IMCI's three original components and (3) reporting on innovations, barriers and opportunities for expanding access to care for children. A single data file was created using all information collected. Analysis was performed using STATA V.11. PARTICIPANTS: In-country teams consisting of representatives of the ministry of health and country offices of WHO and Unicef. RESULTS: Eighty-one per cent of countries reported that IMCI implementation encompassed all three components. Almost half (46%; 44 countries) reported implementation in 90% or more districts as well as all three components in place (full implementation). These full-implementer countries were 3.6 (95% CI 1.5 to 8.9) times more likely to achieve Millennium Development Goal 4 than other (not full implementer) countries. Despite these high reported implementation rates, the strategy is not reaching the children who need it most, as implementation is lowest in high mortality countries (39%; 7/18). CONCLUSION: This survey provides a unique opportunity to better understand how implementation of IMCI has evolved in the 20 years since its inception. Results can be used to assist in formulating strategies, policies and activities to support improvements in the health and survival of children and to help achieve the health-related, post-2015 Sustainable Development Goals.

Improving access to child health services at the community level in Zambia: a country case study on progress in child survival, 2000-2013.

Reductions in under-five mortality in Africa have not been sufficient to meet the Millennium Development Goal #4 (MDG#4) of reducing under-five mortality by two-thirds by 2015. Nevertheless, 12 African countries have met MDG#4. We undertook a four country study to examine barriers and facilitators of child survival prior to 2015, seeking to better understand variability in success across countries. The current analysis presents indicator, national document, and qualitative data from key informants and community women describing the factors that have enabled Zambia to successfully reduce under-five mortality over the last 15 years and achieve MDG#4. Results identified a Zambian national commitment to ongoing reform of national health strategic plans and efforts to ensure universal access to effective maternal, neonatal and child health (MNCH) interventions, creating an environment that has promoted child health. Zambia has also focused on bringing health services as close to the family as possible through specific community health strategies. This includes actively involving community health workers to provide health education, basic MNCH services, and linking women to health facilities, while supplementing community and health facility work with twice-yearly Child Health Weeks. External partners have contributed greatly to Zambia's MNCH services, and their relationships with the government are generally positive. As government funding increases to sustain MNCH services, national health strategies/plans are being used to specify how partners can fill gaps in resources. Zambia's continuing MNCH challenges include basic transportation, access-to-care, workforce shortages, and financing limitations. We highlight policies, programs, and implementation that facilitated reductions in under-five mortality in Zambia. These findings may inform how other countries in the African Region can increase progress in child survival in the post-MDG period.

Factors associated with declining under-five mortality rates from 2000 to 2013: an ecological analysis of 46 African countries.

OBJECTIVE: Inadequate overall progress has been made towards the 4th Millennium Development Goal of reducing under-five mortality rates by two-thirds between 1990 and 2015. Progress has been variable across African countries. We examined health, economic and social factors potentially associated with reductions in under-five mortality (U5M) from 2000 to 2013. SETTING: Ecological analysis using publicly available data from the 46 nations within the WHO African Region. OUTCOME MEASURES: We assessed the annual rate of change (ARC) of 70 different factors and their association with the annual rate of reduction (ARR) of U5M rates using robust linear regression models. RESULTS: Most factors improved over the study period for most countries, with the largest increases seen for economic or technological development and external financing factors. The median (IQR) U5M ARR was 3.6% (2.8 to 5.1%). Only 4 of 70 factors demonstrated a strong and significant association with U5M ARRs, adjusting for potential confounders. Higher ARRs were associated with more rapidly increasing coverage of seeking treatment for acute respiratory infection (ß=0.22 (ie, a 1% increase in the ARC was associated with a 0.22% increase in ARR); 90% CI 0.09 to 0.35; p=0.01), increasing health expenditure relative to gross domestic product (ß=0.26; 95% CI 0.11 to 0.41; p=0.02), increasing fertility rate (ß=0.54; 95% CI 0.07 to 1.02; p=0.07) and decreasing maternal mortality ratio (ß=-0.47; 95% CI -0.69 to -0.24; p<0.01). The majority of factors showed no association or raised validity concerns due to missing data from a large number of countries. CONCLUSIONS: Improvements in sociodemographic, maternal health and governance and financing factors were more likely associated with U5M ARR. These underscore the essential role of contextual factors facilitating child health interventions and services. Surveillance of these factors could help monitor which countries need additional support in reducing U5M.
