Pandemic-related resilience in HPV vaccination programmes - Perspectives from selected countries in Africa on what it will take to vaccinate 90 % of girls by 2030.

The COVID-19 pandemic resulted in widespread disruptions to primary health care and other sectors, halting the majority of routine immunisation services and particularly impacting newer, less routinized HPV vaccine programmes. We present a series of five country case studies, drawing directly from frontline experiences in Côte d'Ivoire, Kenya, Liberia, Zambia, and Senegal to explore potential barriers and enablers of national HPV vaccine programme resiliency in the aftermath of a pandemic. A series of common themes emerged, articulating common challenges to maintaining HPV vaccine programmes, common factors that supported programme resilience, and common themes of resource needs to rebuild stronger routine immunisation programmes to face future threats.

Recovering from the Unprecedented Backsliding in Immunization Coverage: Learnings from Country Programming in Five Countries through the Past Two Years of COVID-19 Pandemic Disruptions.

Between 2020 and 2021, the COVID-19 pandemic severely strained health systems across countries, leaving millions without access to essential healthcare services. Immunization programs experienced a 'double burden' of challenges: initial pandemic-related lockdowns disrupted access to routine immunization services, while subsequent COVID-19 vaccination efforts shifted often limited resources away from routine services. The latest World Health Organization (WHO) and United Nations Children's Fund (UNICEF) estimates suggest that 25 million children did not receive routine vaccinations in 2021, six million more than in 2019 and the highest number witnessed in nearly two decades.

Assessing Comorbidity of Diarrhea and Acute Respiratory Infections in Children Under 5 Years: Evidence From Kenya's Demographic Health Survey 2014.

Kenya is one among the 15 countries that account for three-quarters of the global mortality burden due to diarrhea and respiratory tract infections (RTIs). Comorbidity of diarrhea and acute respiratory infection (ARI) can either be simultaneous (both occurring at the same time) or sequential (where the occurrence of one leads to the occurrence of the other. This study aimed to determine the shared risks that influence comorbidity of diarrhea and RTIs among Kenya's children younger than 5 years.

Succeeding in New Vaccine Introduction: Lessons Learned From the Introduction of Inactivated Poliovirus Vaccine in Cameroon, Kenya, and Nigeria.

Introducing a new vaccine is a large-scale endeavor that can face many challenges, resulting in introduction delays and inefficiencies. The development of national task teams and tools, such as prelaunch trackers, for the introduction of new vaccines (hereafter, "new vaccine introductions" [NVIs]) can help countries implement robust project management systems, front-load critical preparatory activities, and ensure continuous communication around vaccine supply and financing. In addition, implementing postlaunch assessments to take rapid corrective action accelerates the uptake of the new vaccines.
