Mapping the Implementation Determinants of Second Dose Measles Vaccination in the World Health Organization African Region: A Rapid Review.

The second dose of measles-containing vaccines (MCV2) has significant programmatic relevance in the current immunisation landscape because it serves as both an opportunity to reduce measles immunity gaps and strengthen second year of life vaccination platforms. However, MCV2 coverage remains suboptimal across countries in the World Health Organization (WHO) African Region and this puts a significant number of children at risk of morbidity and mortality from measles despite the availability of an effective vaccine. There is an urgent need to strengthen the implementation of MCV2 but this requires a thorough and systematic understanding of contextual factors that influence it. The literature that describes the determinants of implementation of MCV2 in a manner that adequately accounts for the complexity of the implementation context is scarce. Therefore, the purpose of this rapid review was to explore the implementation determinants of MCV2 in the WHO African Region using systems thinking. Literature search in two databases (PubMed and Google Scholar) were conducted. After screening, a total of 17 eligible articles were included in the study. Thematic analysis of extracted data was performed to identify the implementation determinants, after which they were mapped using the Consolidated Framework for Implementation Research (CFIR). A causal loop diagram (CLD) was used to illustrate the linkages between identified determinants. We found 44 implementation determinants across the five CFIR domains, i.e., innovation, outer setting, inner setting, individual, and implementation process. The majority of identified determinants are within the individual domain followed by the inner setting domain. The CLD showed that multiple contingent connections and feedback relationships exist between the identified implementation determinants within and across CFIR domains. The linkages between the implementation determinants revealed three balancing and reinforcing loops each. The findings suggest that implementation determinants of second-dose measles vaccination in the WHO African Region are complex, with multiple interconnections and interdependencies, and this insight should guide subsequent policies. There is an urgent need for further implementation research with embedded CLD in specific settings to inform the design of tailored systemic strategies to improve the implementation effectiveness of MCV2.

Antimicrobial Resistance in the WHO African Region: A Systematic Literature Review 2016-2020.

Antimicrobial resistance (AMR) is a significant global public health threat. This review presents the most recent in-depth review of the situation of the main AMR types in relation to the most commonly prescribed antibiotics in the World Health Organization (WHO) African Region. Underlying genes of resistance have been analyzed where possible. A search to capture published research data on AMR from articles published between 2016 and 2020 was done using PubMed and Google Scholar, with rigorous inclusion/exclusion criteria. Out of 48003 articles, only 167 were included. Among the tested gram-negative bacteria species, Klebsiella spp. remain the most tested, and generally the most resistant. The highest overall phenotypic resistance for imipenem was reported in E. coli, whereas for meropenem, E. coli and Haemophilus spp. showed an equal resistance proportion at 2.5%. For gram-positive bacteria, Streptococcus pneumoniae displayed high resistance percentages to trimethoprim/sulfamethoxazole (64.3%), oxacillin (32.2%), penicillin (23.2%), and tetracycline (28.3%), whereas Staphylococcus aureus contributed to 22.8% and 10% resistance to penicillin and oxacillin, respectively. This review shows that AMR remains a major public health threat. The present findings will help public health decision-makers in developing efficient preventive strategies and adequate policies for antibiotic stewardship and surveillance in line with the global action plan for AMR.

Vaccine value profile for invasive non-typhoidal Salmonella disease

Invasive non-typhoidal Salmonella (iNTS) disease is an under-recognized high-burden disease causing major health and socioeconomic issues in sub-Saharan Africa (sSA), predominantly among immune-naïve infants and young children, including those with recognized comorbidities such as HIV infection. iNTS disease is primarily caused by Salmonella enterica serovar Typhimurium sequence type (ST) 313 and ‘African-restricted clades’ of Salmonella Enteritidis ST11 that have emerged across the African continent as a series of epidemics associated with acquisition of new antimicrobial resistance. Due to genotypes with a high prevalence of antimicrobial resistance and scarcity of therapeutic options, these NTS serovars are designated by the World Health Organization as a priority pathogen for research and development of interventions, including vaccines, to address and reduce NTS associated bacteremia and meningitis in sSA. Novel and traditional vaccine technologies are being applied to develop vaccines against iNTS disease, and the results of the first clinical trials in the infant target population should become available in the near future.The “Vaccine Value Profile” (VVP) addresses information related predominantly to invasive disease caused by Salmonella Enteritidis and Salmonella Typhimurium prevalent in sSA. Information is included on stand-alone iNTS disease candidate vaccines and candidate vaccines targeting iNTS disease combined with another invasive serotype, Salmonella Typhi, that is also common across sSA. Out of scope for the first version of this VVP is a wider discussion on either diarrheagenic NTS disease (dNTS) also associated with Salmonella Enteritidis and Salmonella Typhimurium or the development of a multivalent Salmonella vaccines targeting key serovars for use globally.This VVP for vaccines to prevent iNTS disease is intended to provide a high-level, holistic assessment of the information and data that are currently available to inform the potential public health, economic, and societal value of pipeline vaccines and vaccine-like products. Future versions of this VVP will be updated to reflect ongoing activities such as vaccine development strategies and a “Full Vaccine Value Assessment” that will inform the value proposition of an iNTS disease vaccine. This VVP was developed by a working group of subject matter experts from academia, non-profit organizations, public private partnerships, and multi-lateral organizations, and in collaboration with stakeholders from the World Health Organization African Region. All contributors have extensive expertise on various elements of the iNTS disease VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information.

Advancing Vaccine Strategies for Combatting Placental Malaria: A Path to Effective Implementation

Pregnant women are particularly vulnerable to malaria infection, especially during their first and second pregnancy, despite pre-existing immunity to malaria acquired during childhood. When the parasite-infected red blood cells sequester in the intervillous spaces of the placenta, it leads to various adverse pregnancy outcomes such as maternal anaemia, hypertensive disorders in pregnancy, premature delivery, and infant low birth weight (LBW), which are associated with a higher risk of maternal and foetal/neonate mortality. Anaemia, undernutrition, and HIV infection increase the risk of malaria-associated adverse pregnancy outcomes. The World Health Organisation (WHO) estimates that in 2022, there were approximately 35.4 million pregnancies in the WHO African region of which 36% were exposed to malaria infection, with an estimated 393,000 neonates with low birthweight as a result.

Migration from Epi Info to District Health Information Software 2 for Vaccine-Preventable Disease Surveillance - World Health Organization African Region, 2019-2023.

High-quality vaccine-preventable disease (VPD) surveillance data are critical for timely outbreak detection and response. In 2019, the World Health Organization (WHO) African Regional Office (AFRO) began transitioning from Epi Info, a free, CDC-developed statistical software package with limited capability to integrate with other information systems, affecting reporting timeliness and data use, to District Health Information Software 2 (DHIS2). DHIS2 is a free and open-source software platform for electronic aggregate Integrated Disease Surveillance and Response (IDSR) and case-based surveillance reporting. A national-level reporting system, which provided countries with the option to adopt this new system, was introduced. Regionally, the Epi Info database will be replaced with a DHIS2 regional data platform. This report describes the phased implementation from 2019 to the present. Phase one (2019-2021) involved developing IDSR aggregate and case-based surveillance packages, including pilots in the countries of Mali, Rwanda, and Togo. Phase two (2022) expanded national-level implementation to 27 countries and established the WHO AFRO DHIS2 regional data platform. Phase three (from 2023 to the present) activities have been building local capacity and support for country reporting to the regional platform. By February 2024, eight of 47 AFRO countries had adopted both the aggregate IDSR and case-based surveillance packages, and two had successfully transferred VPD surveillance data to the AFRO regional platform. Challenges included limited human and financial resources, the need to establish data-sharing and governance agreements, technical support for data transfer, and building local capacity to report to the regional platform. Despite these challenges, the transition to DHIS2 will support efficient data transmission to strengthen VPD detection, response, and public health emergencies through improved system integration and interoperability.

Barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating oral health policies in the WHO African region: A scoping review.

To advance oral health policies (OHPs) in the World Health Organization (WHO) African region, barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating OHPs in the region were examined. Global Health, Embase, PubMed, Public Affairs Information Service Index, ABI/Inform, Web of Science, Academic Search Complete, Scopus, Dissertations Global, Google Scholar, WHO's Institutional Repository for Information Sharing (IRIS), the WHO Noncommunicable Diseases Document Repository and the Regional African Index Medicus and African Journals Online were searched. Technical officers at the WHO Regional Office for Africa were contacted. Research studies and policy documents reporting barriers to and facilitators for OHP in the 47 Member States in the WHO African region published between January 2002 and March 2024 in English, French or Portuguese were included. Frequencies were used to summarize quantitative data, and descriptive content analysis was used to code and classify barrier and facilitator statements. Eighty-eight reports, including 55 research articles and 33 policy documents, were included. The vast majority of the research articles and policy documents were country-specific, but they were lacking for most countries. Frequently mentioned barriers across policy at all stages included financial constraints, a limited and poorly organized workforce, deprioritization of oral health, the absence of health information systems, inadequate integration of oral health services within the overarching health system and limited oral health literacy. Facilitators included a renewed commitment to establishing national OHPs, recognition of a need to diversify the oral health workforce, and an increased understanding of the influence of social determinants of health among oral health care providers. Most countries lack a country-specific body of evidence to assist policymakers in anticipating barriers to and facilitators for OHPs. The barriers and facilitators relevant to disparate subnational, national, and regional conditions and circumstances must be considered to advance the creation, dissemination, implementation, monitoring and evaluation of OHPs in the WHO African region.

Approaches for delivery of refractive and optical care services in community and primary care settings.

Uncorrected refractive error is a leading cause of vision impairment which, in most cases, can be managed with the appropriate spectacle correction. In 2021, the World Health Assembly endorsed a global target of a 40-percentage-point increase in effective coverage of refractive error by 2030. To achieve this global target, equitable access to refractive and optical services within community and primary care settings needs to be strengthened. This review will inform the development of technical guidance to support improvements in the testing and correction of refractive error among World Health Organization (WHO) member states. To determine the range of approaches for delivery of refractive and optical care services in community and primary care settings, and the methods employed for their evaluation. We searched CENTRAL, MEDLINE, Embase and Global Health databases, grey literature, and annual reports and websites of relevant organizations involved in eye-care delivery from January 2002 to November 2022 to identify approaches for refractive and optical service delivery. We included observational and interventional studies, reviews, and reports from relevant organizations related to delivering refractive services and optical services for preschool and school-aged children and adults in community and primary care settings published between January 2002 and November 2022. We searched for studies and reports published within the last 20 years because vision impairment due to uncorrected refractive error has only recently become a public health and eye health priority, therefore we did not expect to find much relevant literature until after 2002. Two review authors screened titles, abstracts and full texts, and extracted data. We resolved any discrepancies through discussion. We synthesized data, and presented results as tables, figures, and case studies. This project was led by the World Health Organization (WHO) Vision and Eye Care Programme. We identified 175 studies from searches of databases and grey literature, 146 records from company reports, and 81 records from website searches of relevant organizations that matched our inclusion criteria. Delivery approaches for refractive and optical services in community care included school-based, pharmacy, and outreach models, whereas primary care approaches comprised vision centre, health centre, and a combination of vision or health centre and door-to-door delivery. In community care, school-based and outreach approaches were predominant, while in primary care, a vision-centre approach was mainly used. In the WHO African region, the school-based and outreach approaches were mainly reported while, in the Americas, the outreach approach was mostly used. Very few approaches for service delivery were reported in the WHO Eastern Mediterranean region. Prominent gaps exist in the evaluation of the approaches, and few studies attempted to evaluate the approaches for delivery of refractive and optical care services. We comprehensively describe a range of approaches for delivery of refractive and optical services in community and primary care. Further evaluation of their effectiveness will better inform the application of these service-delivery approaches. The study outcomes will help guide WHO member states in strengthening refractive and optical services at community and primary care levels. This scoping review was supported by the Vision and Eye care Programme, World Health Organization and ATscale Global Partnership. The protocol of this scoping review was published in the Open Source Framework.

COVID-19 Vaccination Coverage - World Health Organization African Region, 2021-2023.

With the availability of authorized COVID-19 vaccines in early 2021, vaccination became an effective tool to reduce COVID-19-associated morbidity and mortality. Initially, the World Health Organization (WHO) set an ambitious target to vaccinate 70% of the global population by mid-2022. However, in July 2022, WHO recommended that all countries, including those in the African Region, prioritize COVID-19 vaccination of high-risk groups, including older adults and health care workers, to have the greatest impact on morbidity and mortality. As of December 31, 2023, approximately 860 million doses of COVID-19 vaccine had been delivered to countries in the African Region, and 646 million doses had been administered. Cumulatively, 38% of the African Region's population had received ≥1 dose, 32% had completed a primary series, and 21% had received ≥1 booster dose. Cumulative total population coverage with ≥1 dose ranged by country from 0.3% to 89%. Coverage with the primary series among older age groups was 52% (range among countries=15%-96%); primary series coverage among health care workers was 48% (range=13%-99%). Although the COVID-19 public health emergency of international concern was declared over in May 2023, current WHO recommendations reinforce the need to vaccinate priority populations at highest risk for severe COVID-19 disease and death and build more sustainable programs by integrating COVID-19 vaccination into primary health care, strengthening immunization across the life course, and improving pandemic preparedness.

Low Measles Vaccination Coverage and Spatial Analysis of High Measles Vaccination Dropout in Ethiopia's Underprivileged Areas.

(1) Background: Measles remains a major cause of disease and death worldwide, especially in the World Health Organization African Region. This study aimed to estimate the coverage of measles vaccinations and map the spatial distribution of measles vaccination dropout in Ethiopia; (2) Methods: A cross-sectional survey was conducted in Ethiopia's underprivileged areas. The study included 3646 mothers/caregivers of children. ArcGIS for the spatial analysis, Global Moran's I statistic for spatial autocorrelation, and Getis-Ord Gi* statistics for hot spot analysis were applied; (3) Results: Overall, coverages of measles-containing-vaccine first- and second-doses were 67% and 35%, respectively. Developing regions had the lowest coverages of measles-containing-vaccine first- and second-doses, 46.4% and 21.2%, respectively. On average, the measles vaccination dropout estimate was 48.3%. Refugees had the highest measles vaccination dropout estimate (56.4%). The hot spot analysis detected the highest burden of measles vaccination dropout mainly in the northeastern parts of Ethiopia, such as the Afar Region's zones 1 and 5, the Amhara Region's North Gondar Zone, and peripheral areas in the Benishangul Gumuz Region's Assosa Zone; (4) Conclusions: The overall measles vaccination coverages were relatively low, and measles vaccination dropout estimates were high. Measles vaccination dropout hot spot areas were detected in the northeastern parts of Ethiopia.

Barriers to and facilitators for the creation, dissemination, implementation, monitoring, and evaluation of oral health policies in the WHO Africa region: A scoping review protocol.

Evidence-informed oral health policies (OHP) can be instrumental in ending the neglect of oral health globally. When appropriately developed and implemented, OHP can improve the efficiency of healthcare systems and the quality of health outcomes. However, more than half of the countries in the World Health Organization (WHO) African region do not have an oral health policy or even the existence of a policy in need of additional and more national-specific OHP as part of non-communicable diseases and universal health coverage agendas. The objective of this protocol's study is to determine the barriers to and facilitators for the creation, dissemination, implementation, monitoring, and evaluation of OHP in the WHO Africa region. We will conduct a systematic search in Global Health, Embase, PubMed, PAIS, ABI/Inform, Web of Science, Academic Search Complete, Scopus, databases that index gray literature, and the WHO policy repositories. We will include qualitative, quantitative, or mixed-methods research studies and OHP documents published since January 1, 2002, which address stakeholders' perceptions and experiences regarding barriers to and facilitators for the creation, dissemination, implementation, monitoring, and evaluation of OHP in countries part of the WHO African region. We will produce descriptive statistics (frequencies and proportions) for quantitative data and conduct descriptive content analysis for qualitative data. To effectively establish evidence-based OHP in the WHO African region, it is crucial to recognize existing challenges and opportunities for progress. The findings of this review will be relevant for Chief Dental Officers at ministries of health, administrators of dental schools, or academic institutions in the WHO African region and will inform a stakeholder dialogue meeting in Kenya in November of 2023.

Status of Routine Immunization Coverage in the World Health Organization African Region Three Years into the COVID-19 Pandemic.

Data from the WHO and UNICEF Estimates of National Immunization Coverage (WUENIC) 2022 revision were analyzed to assess the status of routine immunization in the WHO African Region disrupted by the COVID-19 pandemic. In 2022, coverage for the first and third doses of the diphtheria-tetanus-pertussis-containing vaccine (DTP1 and DTP3, respectively) and the first dose of the measles-containing vaccine (MCV1) in the region was estimated at 80%, 72% and 69%, respectively (all below the 2019 level). Only 13 of the 47 countries (28%) achieved the global target coverage of 90% or above with DTP3 in 2022. From 2019 to 2022, 28.7 million zero-dose children were recorded (19.0% of the target population). Ten countries in the region accounted for 80.3% of all zero-dose children, including the four most populated countries. Reported administrative coverage greater than WUENIC-reported coverage was found in 19 countries, highlighting routine immunization data quality issues. The WHO African Region has not yet recovered from COVID-19 disruptions to routine immunization. It is critical for governments to ensure that processes are in place to prioritize investments for restoring immunization services, catching up on the vaccination of zero-dose and under-vaccinated children and improving data quality.

Monitoring progress on Antimicrobial Resistance (AMR) response in the World Health Organization African region: Insights from the Tracking AMR Country Self-Assessment Survey (TrACSS) 2021 results for the human health sector.

Antimicrobial resistance (AMR) is a major 21st century global health challenge. The WHO African Region Member States committed to develop and implement multisectoral national action plans (NAPs) that address AMR, in line with the Global Action Plan on AMR (GAP). The aim of this paper is to present the progress of AMR response in the WHO African Region based on the annual Tracking AMR Country Self-Assessment Survey (TrACSS), with a focus on human health indicators. This was a secondary data analysis of responses from forty-one countries that participated in the 2021 TrACSS. Of the 41 countries that responded to the 2021 TrACSS, 35(85%) have developed NAPs. Fifteen 15(37%) of countries have functional AMR multisector working groups. 55% (21/41) of countries are collating data nationally on AMR surveillance. Forty nine percent of countries conducted small-scale AMR awareness campaigns and 53% (21/41) covered AMR in some pre- and in-service training for human health workers. While 83% of countries reported having laws and regulations on the prescription and sale of antimicrobials, only 32% (13/41) have national systems for monitoring antimicrobial use. Twenty-three (58%, 23/41) reported having Infection Prevention and Control (IPC) programs at select health facilities. Countries have developed and are implementing AMR NAPs. Gaps still exist across key indicators monitored through TrACSS. Effective AMR response requires established functional multisectoral governance mechanisms in the One Health approach; political commitment, sustainable funding, and clear monitoring and reporting is critical.

Investigating Infection Prevention and Control Practices among Healthcare Workers in Kasese District, Uganda: Factors and Implications for Ebola Preparedness

The World Health Organization (WHO) African region often faces numerous public health emergencies, with a significant proportion caused by infectious diseases. Ebola virus disease (EVD) is a high-consequence pathogen of particular concern due to its high mortality rate and potential for global transmission. The study aimed to investigate infection prevention and control (IPC) practices with factors associated with the practice among health care workers (HCWs) in Kasese district, Uganda. The study design was cross-sectional, utilizing both qualitative and quantitative methods. The study population consisted of HCWs working in six selected Health Centre III facilities in sub-counties bordering the Democratic Republic of Congo (DRC). A sample of 106 HCWs was purposively selected and data collection involved structured questionnaires, and then data analysis was done using descriptive statistics and logistic regression. The study reveals that a majority of HCWs were female (55.7%), worked in outpatient departments (49.1%), had 6-10 years of service (43.4%), held certificates as their highest education level (48.1%), and were predominantly nurses (53.8%). IPC practices were found to be low, with 72.6% of participants exhibiting inappropriate IPC practices. Individual factors influencing low IPC practices included the duration of IPC training, knowledge, attitude towards IPC, and education level, all statistically significant (P < 0.05). Similarly, health facility factors such as the accessibility of IPC guidelines and personal protective equipment (PPE), availability of sanitizer/soap, and proper and continuous IPC training/continuing medical education (CME) were associated with low IPC practice (P < 0.05). In conclusion, the study highlights a low level of IPC practice among HCWs in Health Centre Threes in Kasese District, with both individual and health facility factors contributing to this issue. Recommendations include training HCWs in IPC and organizing regular cascade training, providing IPC knowledge as part of their daily duties, ensuring confidence in managing Ebola during outbreaks, maintaining IPC strategies implemented during EVD outbreaks, and supplying IPC materials to healthcare facilities. These efforts, coupled with increased staffing, can significantly enhance protection and performance in public healthcare services.

Обзор актуальных рисков заноса инфекционных болезней на территорию Российской Федерации из стран Африканского континента

The paper presents generalized epidemiological data and analyzes the situation in the countries of the African region on infectious diseases requiring measures for sanitary protection of the territory of the Russian Federation. The epidemiological analysis was carried out on the basis of data from the official website of the African Bureau of the World Health Organization (WHO), the African Center for Disease Prevention and Control (CDC), Ministries of Health of the relevant countries, other international organizations, as well as materials of publications in the public domain. The paper summarizes and systematizes data on the incidence and territorial spread of diseases in the region from the perspective of possible risks for those visiting it. The presented data on infectious diseases make it possible to navigate issues related to the risk of infection with infectious diseases, to determine the factors and seasonality of the increased risk of infection, to predict the possibility of importing diseases to the Russian Federation. Keywords: infectious diseases, WHO African region, ensuring sanitary and epidemiological well-being, risk of drift, sanitary protection of the territory, plague, cholera, malaria, EVD, MVD.

Development of a Consolidated Health Facility Masterlist Using Data From Polio Electronic Surveillance in the World Health Organization African Region.

Geospatial data reporting from surveillance and immunization efforts is a key aspect of the World Health Organization (WHO) Global Polio Eradication Initiative in Africa. These activities are coordinated through the WHO Regional Office for Africa Geographic Information Systems Centre. To ensure the accuracy of field-collected data, the WHO Regional Office for Africa Geographic Information Systems Centre has developed mobile phone apps such as electronic surveillance (eSURV) and integrated supportive supervision (ISS) geospatial data collection programs. While eSURV and ISS have played a vital role in efforts to eradicate polio and control other communicable diseases in Africa, disease surveillance efforts have been hampered by incomplete and inaccurate listings of health care sites throughout the continent. To address this shortcoming, data compiled from eSURV and ISS are being used to develop, update, and validate a Health Facility master list for the WHO African region that contains comprehensive listings of the names, locations, and types of health facilities in each member state. The WHO and Ministry of Health field officers are responsible for documenting and transmitting the relevant geospatial location information regarding health facilities and traditional medicine sites using the eSURV and ISS form; this information is then used to update the Health Facility master list and is also made available to national ministries of health to update their respective health facility lists. This consolidation of health facility information into a single registry is expected to improve disease surveillance and facilitate epidemiologic research for the Global Polio Eradication Initiative, as well as aid public health efforts directed at other diseases across the African continent. This review examines active surveillance using eSURV at the district, country, and regional levels, highlighting its role in supporting polio surveillance and immunization efforts, as well as its potential to serve as a fundamental basis for broader public health initiatives and research throughout Africa.

Toward political economy of sustainable financing for immunization in the World Health Organization African Region through a systems thinking lens

There is an urgent need for countries in Africa to allocate more domestic financial resources to immunization so that national immunization programmes can attain self-reliance in line with World Health Organization's Immunization Agenda 2030. However, resource allocation is fundamentally a political process because other competing needs exist. Political economy analysis (PEA) can guide policy influencers in their engagement with decision makers to tilt their interest in support of sustainable immunization financing. PEA can provide a deeper understanding of the potential constraints and facilitators of a policy direction to expand the fiscal space for immunization using domestic resources within the context of a country's socioeconomic and political realities. To further advance the usefulness of PEA for decision making, a systems thinking lens should be applied to account for the inherent complexity of the social systems involved in resource allocation and implementation. Several methods and tools of systems thinking already exist and can be employed. Causal loop diagrams, when incorporated in a PEA of sustainable financing for immunization can aid the identification of feedback loops which can be used as leverage points for intervention.

Progress Toward Measles Elimination - African Region, 2017-2021.

Worldwide, measles remains a major cause of disease and death; the highest incidence is in the World Health Organization African Region (AFR). In 2011, the 46 AFR member states established a goal of regional measles elimination by 2020; this report describes progress during 2017-2021. Regional coverage with a first dose of measles-containing vaccine (MCV) decreased from 70% in 2017 to 68% in 2021, and the number of countries with ≥95% coverage decreased from six (13%) to two (4%). The number of countries providing a second MCV dose increased from 27 (57%) to 38 (81%), and second-dose coverage increased from 25% to 41%. Approximately 341 million persons were vaccinated in supplementary immunization activities, and an estimated 4.5 million deaths were averted by vaccination. However, the number of countries meeting measles surveillance performance indicators declined from 26 (62%) to nine (22%). Measles incidence increased from 69.2 per 1 million population in 2017 to 81.9 in 2021. The number of estimated annual measles cases and deaths increased 22% and 8%, respectively. By December 2021, no country in AFR had received verification of measles elimination. To achieve a renewed regional goal of measles elimination in at least 80% of countries by 2030, intensified efforts are needed to recover and surpass levels of surveillance performance and coverage with 2 MCV doses achieved before the COVID-19 pandemic.

Evaluation of Laboratories Supporting Invasive Bacterial Vaccine-Preventable Disease (IB-VPD) Surveillance in the World Health Organization African Region, through the Performance of Coordinated External Quality Assessment.

(1) Background: Laboratories supporting the invasive bacteria preventable disease (IB-VPD) network are expected to demonstrate the capacity to identify the main etiological agents of pediatric bacterial meningitis (PBM) (Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae) on Gram stains and in phenotypic identification. Individual reports of sentinel site (SSL), national (NL) and regional reference (RRL) laboratories participating in the World Health Organization (WHO)-coordinated external quality assessment, distributed by the United Kingdom National External Quality Assessment (EQA) Services (UK NEQAS) for Microbiology between 2014 and 2019 were analyzed. (2) Methods: The panels consisted of (1) unstained bacterial smears for Gram staining, (2) viable isolates for identification and serotyping/serogrouping (ST/SG) and (3) simulated cerebral spinal fluid (CSF) samples for species detection and ST/SG using polymerase chain reaction (PCR). SSLs and NLs tested for Gram staining and species identification (partial panel). RRLs, plus any SSLs and NLs (optionally) also analyzed the simulated CSF samples (full panel). The passing score was ≥75% for NLs and SSLs, and ≥90% for RRLs and NLs/SSLs testing the full panel. (3) Results: Overall, 63% (5/8) of the SSLs and NLs were able to correctly identify the targeted pathogens, in 2019; but there were challenges to identify Haemophilus influenzae either on Gram stains (35% of the labs failed 2014), or in culture. Individual performance showed inconsistent capacity, with only 39% (13/33) of the SSLs/NLs passing the EQA exercise throughout all surveys in which they participated. RRLs performed well over the study period, but one of the two failed to reach the minimal passing score in 2016 and 2018; while the SSLs/NLs that optionally tested the full panel scored between 75% and 90% (intermediate pass category). (4) Conclusions: We identified a need for implementing a robust quality management system for timely identification of the gaps and then implementing corrective and preventive actions, in addition to continuous refresher training in the SSLs and NLs supporting the IB-VPD surveillance in the World Health Organization, Regional Office for Africa (WHO AFRO).

COVID-19 Vaccination in the WHO African Region: Progress Made in 2022 and Factors Associated.

This study summarizes progress made in rolling out COVID-19 vaccinations in the African region in 2022, and analyzes factors associated with vaccination coverage. Data on vaccine uptake reported to the World Health Organization (WHO) Regional Office for Africa by Member States between January 2021 and December 2022, as well as publicly available health and socio-economic data, were used. A negative binomial regression was performed to analyze factors associated with vaccination coverage in 2022. As of the end of 2022, 308.1 million people had completed the primary vaccination series, representing 26.4% of the region's population, compared to 6.3% at the end of 2021. The percentage of health workers with complete primary series was 40.9%. Having carried out at least one high volume mass vaccination campaign in 2022 was associated with high vaccination coverage (β = 0.91, p < 0.0001), while higher WHO funding spent per person vaccinated in 2022 was correlated with lower vaccination coverage (β = -0.26, p < 0.03). All countries should expand efforts to integrate COVID-19 vaccinations into routine immunization and primary health care, and increase investment in vaccine demand generation during the transition period that follows the acute phase of the pandemic.
