Leveraging the CORE Group Partners Project Polio Infrastructure to Integrate COVID-19 Vaccination and Routine Immunization in South Sudan

INTRODUCTION

Countries with fragile health systems like South Sudan experienced significant impacts on routine immunization during the COVID-19 pandemic. Routine immunization in children aged younger than 1 year declined due to pandemic-related constraints and was compounded by the introduction of the COVID-19 vaccine, which was met with hesitancy and reluctance. When South Sudan reported the first COVID-19 case in March 2020, the CORE Group Partners Project (CGPP) rapidly integrated the COVID-19 outbreak response into its ongoing polio eradication activities, leveraging the existing polio infrastructure and human resources. We describe the integration process, results, and challenges and detail the impact of the integration on coverage for both routine immunization and COVID-19 vaccinations.

METHODS

Efforts to integrate COVID-19 vaccination and routine immunization service delivery were implemented in 5 phases: assessing the need, developing multisector collaborations, developing a service delivery plan, assessing implementation readiness, and implementing and evaluating the service delivery plan. Integration efforts prioritized coordination, training vaccinators and volunteers, development of microplans, data management, and last-mile vaccine delivery. Integrated service delivery was implemented through "one-stop shop" sessions where communities accessed routine immunizations for children, COVID-19 vaccinations for adults, and other primary health services.

RESULTS

Integrating health service delivery contributed to improved routine immunization coverage among children, improved COVID-19 vaccination coverage among adults, reduced cost for service delivery, and increased access to more comprehensive health services in hard-to-reach communities. COVID-19 vaccinations were delivered at US$4.70 per dose, a cost substantially lower than other reported delivery mechanisms.

CONCLUSION

Integration can yield positive results and improve access to vaccination and other health services for communities. However, it requires clear policy guidelines, commitment, and strong collaboration. Challenges included resistance from stakeholders, overstretched human resources, and diversion of funding and attention from program areas, which were overcome through deliberate high-level advocacy, partnership, and intensified community engagement.

Why Communities Should Be the Focus to Reduce Stigma Attached to COVID-19

Since 1999, the CORE Group Polio Project (CGPP) has developed, refined, and deployed effective strategies to mobilize communities to improve vaccine uptake for polio (and other vaccine-preventable diseases such as measles) and conduct surveillance for infectious disease threats in high-risk, border, and hard-to-reach locations. CORE Group Polio Project teams have been called upon to address the COVID-19 pandemic, and, like with polio, the pandemic response is impacted by stigma in all areas of response, from health education, testing, contact tracing, and even treatment for infected individuals. The CGPP has reached back into its polio experience and is redeploying successful community engagement activities to address stigma as part of the COVID-19 response. Across country programs, community health volunteers communicate risk and behavior change at the household level by integrating health education and promotion activities with a focus on practical measures of COVID-19 prevention. Moreover, leveraging established and trusted partnerships with community networks and community leaders are providing lessons that can be adopted by the global community. The CGPP offers three overarching recommendations to curb stigma: 1) facilitating inclusive community engagement, 2) leveraging existing community networks and 3) cocreating with community leaders.

Evaluation of the Functionality and Effectiveness of the CORE Group Polio Project's Community-Based Acute Flaccid Paralysis Surveillance System in South Sudan

This article describes the functionality and effectiveness of a community-based acute flaccid paralysis (AFP) surveillance system designed and implemented by the CORE Group Polio Project (CGPP) in conflict-affected and inaccessible areas of South Sudan between October 2015 and September 2017. The findings are based on interviews with key informants and focus group discussions as well as data from the CGPP and the management information system of the WHO. Through the implementing partners, the CGPP identified and built the capacity of the community-based surveillance (CBS) system, a system consisting of county supervisors, payam (sub-county) assistants, and community key informants. This structure played a critical role in the identification and reporting of AFP cases. The CGPP also established partnerships with other key players-local and international-to reach greater numbers of people, particularly displaced populations. Evaluation findings show an increase from 0.0% to 56.4% of cases reported through the CBS system between January 2016 and June 2017, and 80.0% of the cases reported within WHO standards of 24-48 hours were through the CBS system, whereas 20.0% were through the facility-based system. The CBS system also recorded an increase from 36.0% in 2014 to 92.0% in December 2016 for the number of counties that were reporting AFP. A CBS system is, therefore, a valuable complement to facility-based surveillance in insecure environments or where the population has limited access to facilities. Community-based surveillance systems also have the potential to identify cases of other infectious diseases of public health importance.
