Predictive modeling was performed an autoregressive integrated moving average (ARIMA) model. A total 32,602,734 events were recorded across regions from 2019 to 2022. Despite declining rates 2020, there notable rebound 2021, indicating resilience Tanzania's immunization program. analysis also highlighted regional differences when standardized per 1000 people. Seasonal fluctuations observed rates, with BCG showing most stable trend. indicated increasing coverage by 2023.

American Journal of Human Biology, Год журнала: 2025, Номер 37(2)

Опубликована: Фев. 1, 2025

ABSTRACT Objectives Vaccines are highly successful in preventing disease, but misinformation has fueled vaccine hesitancy globally, thereby reducing immunization rates and weakening herd immunity. Vaccine knowledge among hunter‐gatherers is a crucial area of research intervention, as their mobile lifestyle exacerbates other challenges, such marginalization medical mistrust. Methods In our exploratory study, we surveyed 91 Hadzabe adults across six camps (mean age = 39, 46% female) about vaccines safety efficacy. Differences between sexes were tested using Fisher's exact tests. Results Half participants reported not knowing what is, while one‐third described protecting health or disease. About 32% unsure safety, most strongly agreed effective (65.3%). A majority (72%) important for children, yet only on importance adults. More females than males expressed uncertainty the adult ( p 0.03). Participants sample perceived less more safe general Tanzanian population, based 2018 Wellcome data. Discussion sample, results indicate that generally agree important, particularly gaps remain. There clear need to communicate information community culturally appropriate manner. Such efforts critical safeguarding Indigenous populations experiencing greater market integration, supporting access against diseases.

Immediately following the emergency use authorizations of COVID-19 vaccines, governments around world made these products available to their populations and later started implementing differential rules for vaccinated unvaccinated citizens regarding mobility access venues services. The Oxford Government Response Tracker (OxCGRT) is a time series database that reflects extent public health measures in each country. On basis OxCGRT Containment Health Index, we calculated corresponding discrimination index by subtracting daily values individuals. resulting metric provides cursory quantification experienced individuals throughout 2021 2022. Patterns data show high degree with great numeric temporal differences between jurisdictions. Around 90% countries Europe North South America discriminated against at some point during pandemic. least amount was found Central Africa. In order move towards sustainable post-pandemic recovery prevent discriminatory policies future, recommend human rights protections be expanded prohibition extended beyond limited list grounds.

Root causes of COVID-19 data backlogs: a mixed methods analysis in four African countries

Oxford Open Digital Health, Год журнала: 2024, Номер 2(Supplement_1), С. i16 - i28

Опубликована: Янв. 1, 2024

Abstract With the unprecedented scale and scope of COVID-19 vaccination response, many countries used digital systems to capture vaccine administration data. Data backlogs, a build-up information captured via paper forms not yet entered into systems, were common across countries. This study aimed identify root causes data backlogs in Democratic Republic Congo, Kenya, Senegal Tanzania based on primary (interviews observations at delivery sites) secondary Root related technology (system slowdowns, insufficient devices limited system functionality), infrastructure (lack reliable internet bundles), processes (incongruence between tools, separate collection entry, lack integration with routine immunization standard operating procedures) people (staff shortages, large workloads non-payment staff). Recommendations inform include: (i) use country-led, coordinated, iterative approach for design introduction, (ii) start minimum viable product (iii) proactively address needs health workforce. As global emergency ends, these findings can help broader strengthening efforts improve effectiveness, resilience pandemic preparedness. Abrégé Face à l’ampleur et la portée sans précédent de campagne vaccinale contre COVID-19, nombreux pays ont utilisé des systèmes numériques pour recueillir données sur l’administration du vaccin. Tous les connu retards données, soit une accumulation d’informations recueillies au moyen formulaires papier qui n’avaient pas encore été saisies dans numériques. Cette étude vise cerner premières ces en République démocratique Sénégal Tanzanie base primaires (entretiens sites d’administration vaccin) secondaires. Les étaient liées technologie (ralentissements systèmes, insuffisance appareils fonctionnalité limitée systèmes), l’infrastructure (absence forfaits liaison Internet fiables), aux processus (incompatibilité entre outils numériques, collecte saisie séparées manque d’intégration avec vaccinations absence procédures opérationnelles normalisées) personnel (manque d’effectifs, charges travail importantes non-paiement personnel). recommandations informer comprennent: utiliser approche itérative, coordonnée dirigée par conception mise place commencer un produit répondre besoins santé amont problèmes. La crise mondiale liée touchant sa fin, résultats sont susceptibles d’éclairer renforcement leur ensemble visant améliorer l’efficacité, résilience préparation pandémies. Resumen Ante escala y el alcance sin precedentes vacunación como respuesta muchos países utilizaron sistemas digitales para registrar datos sobre administración las vacunas. En todos los era común que información recabada través formularios papel se acumulara ingresarse digitales. El objetivo este estudio consistió identificar causas fundamentales acumulación procesar contra República Democrática del Kenia, partir primarios (entrevistas observaciones sitios vacunación) secundarios. Las esa estaban relacionadas con tecnología (desaceleraciones sistema, dispositivos insuficientes funcionalidad limitada sistema), infraestructura (falta conexión confiable paquetes datos), procesos (incongruencia herramientas digitales, recopilación e ingreso por separado, falta integración inmunización rutina procedimientos operativos estándar) personas (escasez personal, grandes cargas trabajo pago personal). siguientes son algunas recomendaciones datos: utilizar enfoque iterativo, coordinado dirigido país diseño introducción comenzar producto mínimo atender manera proactiva necesidades personal salud. Ahora está terminando emergencia mundial estos hallazgos pueden servir esfuerzos más amplios fortalecimiento sistema salud dirigidos mejorar efectividad, resiliencia preparación pandemias.
