Effective spontaneous AEFI reporting is the first step to ensuring vaccine safety. Half of the global population lives in countries with weak vaccine safety monitoring systems, especially in the African, Eastern Mediterranean, and Western Pacific regions. Further, Immunisation services have been upscaled without commensurate effective AEFI surveillance systems. Hence, this study aims to comprehensively investigate the impediments to an effective AEFI surveillance system. Given the programmatic and regulatory implications, understanding these impediments would facilitate the development and implementation of policies and strategies to strengthen the AEFI surveillance system in Nigeria. A qualitative research design (using a grounded theory approach) was employed by conducting ten key informant interviews and two Focus Group Discussion sessions among the study population to identify the barriers impeding optimal AEFI surveillance and documentation in Nigeria. This study found that the AEFI surveillance system is in place in Nigeria. However, its functionality is sub-optimal, and the potential capacity is yet to be fully harnessed due to health systems and socio-ecological impediments. The identified impediments are human-resource-related issues- knowledge gaps; limited training; lack of designated officers for AEFI; excessive workload; poor supportive supervision and attitudinal issues; caregiver's factor; governance and leadership- moribund AEFI committee; lack of quality supervisory visit and oversight and weak implementation of AEFI policy guidance. Others include funding and logistics issues- no dedicated budget provision and weak referral mechanism; insecurity; socio-economic and infrastructural deficits- poverty, geographical barriers, limited ICT skills, and infrastructure; and poor feedback and weak community engagement by the health workers. Findings from this study provide empirical evidence and serve as an advocacy tool for vaccine pharmacovigilance strengthening in Nigeria. Addressing the impediments requires health system strengthening and a whole-of-the-society approach to improve vaccine safety surveillance, restore public confidence and promote vaccine demand, strengthen PHC services, and contribute to attaining UHC and SDGs.

IntroductionNoma is a disfiguring gangrenous disease of the orofacial tissue and predominantly affects malnourished children. The tissue gangrene or necrosis starts in the mouth and eventually spreads intra-orally with the destruction of soft and hard tissues. If not controlled, the natural course of the condition leads to a perforation through the skin of the face, creating a severe cosmetic and functional defect, which often affects the mid-facial structures. Furthermore, the course of the disease is fulminating, and without timely intervention, it is fatal.Materials and methodsA retrospective clinical cross-sectional study was conducted to assess the sequela and severity of Noma in Ethiopia. Medical records of patients diagnosed with Noma were reviewed. The medical files were obtained from Yekatik 12 Hospital, Facing Africa, and the Harar project,-the three major Noma treatment centers in Ethiopia. The severity of facial tissue damage and the extent of mouth trismus (ankylosis) were examined based on the NOIPTUS score.ResultsA total of 163 medical records were reviewed. Of those, 52% (n = 85) and 48% (n = 78) have reported left-sided and right-sided facial defects, respectively. The facial defects ranged from minor to severe tissue damage. In other words, 42.3% (n = 69), 30.7% (n = 50), 19% (n = 31), and 8% (n = 13) have reported Grade-2 (25-50%), Grade-3 (50-75%), Grade-1 (0-25%), and Grade-4 (75-100%) tissue damages respectively. Cheek, upper lip, lower lip, nose, hard palate, maxilla, oral commissure, zygoma, infra-orbital region, mandible, and chin are oftentimes the major facial anatomic regions affected by the disease in the individuals identified in our review. Complete loss of upper lip, lower lip, and nose were also identified as a sequela of Noma.DiscussionThe mortality rate of Noma is reported to vary between 85% and 90%. The few survivors suffer from disfigurement and functional impairment affecting speech, breathing, mastication, and/or even leading to changes in vision. Often, the aesthetic damage becomes a source of stigma, leading to isolation from society, as well as one's family. Similarly, our review found a high level of facial tissue damage and psychiatric morbidity.

To ensure sustainable development, there is a limit to the extent of urbanization. Thus, rural development is an essential strategy that many nations must work on to ensure optimal economic, environmental, and social outcomes at a country level. However, rural development in itself is challenging because rural communities typically have limited resources and capabilities to address common livelihood challenges, let alone take on new economic roles. Hence, as part of rural revitalization strategies, innovation plays a critical role. A wide range of technologies can facilitate innovation in rural development, including the internet and new agricultural technologies. In addition, new mindsets and shifts in values, such as the changing trends of work and consumerism, can create opportunities for rural areas to adopt innovation and develop new growth engines. However, it should be noted that the nature of innovation in rural and urban settings are different. In rural regions, growth could be enabled through more specific types of innovations, including frugal innovation, inclusive innovation, and social innovation. To enable these forms of innovations in rural areas, this paper proposes a three-dimensional process model that includes pro-social technological innovation policy, rural innovation governance, and dynamic networks that close the gap between rural and urban innovation systems. Examples from China, such as the development of Tengtou Village and Taobao Villages serve to demonstrate these concepts. Overall, the discussions in the paper suggest that to enable innovation in rural development, it is necessary to foster closer interactions between rural and urban innovation ecosystems for the former to leverage the latter's technologies, networks, and resources.
