CDC's COVID-19 International Vaccine Implementation and Evaluation Program and Lessons from Earlier Vaccine Introductions.

The US Centers for Disease Control and Prevention (CDC) supports international partners in introducing vaccines, including those against SARS-CoV-2 virus. CDC contributes to the development of global technical tools, guidance, and policy for COVID-19 vaccination and has established its COVID-19 International Vaccine Implementation and Evaluation (CIVIE) program. CIVIE supports ministries of health and their partner organizations in developing or strengthening their national capacities for the planning, implementation, and evaluation of COVID-19 vaccination programs. CIVIE's 7 priority areas for country-specific technical assistance are vaccine policy development, program planning, vaccine confidence and demand, data management and use, workforce development, vaccine safety, and evaluation. We discuss CDC's work on global COVID-19 vaccine implementation, including priorities, challenges, opportunities, and applicable lessons learned from prior experiences with Ebola, influenza, and meningococcal serogroup A conjugate vaccine introductions.

Provincial Intra-Action Review of the COVID-19 Vaccination Programme: Opportunities to Improve Vaccine Response in North Kivu, Democratic Republic of Congo.

Background: Low levels of COVID-19 vaccination coverage in many countries prompted the use of rapid assessments to characterize barriers to vaccination and identify corrective measures. The World Health Organization recommended the use of intra-action reviews (IARs) to identify best practices, gaps, and lessons learned to make real-time improvements to the COVID-19 vaccination response. Objective: The Democratic Republic of the Congo (DRC) implemented a national IAR in July 2021 that was poorly attended by the provincial health level, where vaccination activities are planned and implemented. To bridge this gap, we proposed sub-national IARs focused on COVID-19 vaccine program implementation at the provincial level. Methods: Using the WHO methodology, we organized a four-day provincial IAR workshop and invited national, provincial and health zone Ministry of Health (MoH) representatives and private and non-governmental organizations involved in the provincial COVID-19 vaccination response. Participants were divided into six groups based on their expertise, affiliation, and role within the health system to assess and identify lessons learned, challenges and the solutions within each of the six technical areas: (1) coordination, planning and monitoring; (2) service delivery; (3) risk communication and community engagement; (4) adverse effects following immunization (AEFI); (5) logistics; (6) and data management, monitoring and evaluation. Results: The first provincial COVID-19 IAR was conducted in Goma, North Kivu, from January 19-22, 2022. A total of 56 participants came from provincial and health zone offices, and non-governmental organizations. Through work group discussions, they identified best practices, challenges, and lessons learned, and made recommendations to improve implementation of vaccination activities and reach coverage targets. Activities were proposed to operationalize recommendations and address challenges to improve the provincial response. Conclusion: This provincial IAR was a useful tool for reviewing progress and areas of improvement, while evaluating aspects of the COVID-19 vaccine rollout. It provided a means to share information with vaccination partners on areas of intervention, tailored to the local context.

Vaccination information, motivations, and barriers in the context of meningococcal serogroup A conjugate vaccine introduction: A qualitative assessment among caregivers in Burkina Faso, 2018.

BACKGROUND: In March 2017, Burkina Faso introduced meningococcal serogroup A conjugate vaccine (MACV) into the Expanded Programme on Immunization. MACV is administered to children aged 15-18 months, concomitantly with the second dose of measles-containing vaccine (MCV2). One year after MACV introduction, we assessed the sources and content of immunization information available to caregivers and explored motivations and barriers that influence their decision to seek MACV for their children. METHODS: Twenty-four focus group discussions (FGDs) were conducted with caregivers of children eligible for MACV and MCV2. Data collection occurred in February-March 2018 in four purposively selected districts, each from a separate geographic region; within each district, caregivers were stratified into groups based on whether their children were unvaccinated or vaccinated with MACV. FGDs were recorded and transcribed. Transcripts were coded and analyzed using qualitative content analysis. RESULTS: We identified many different sources and content of information about MACV and MCV2 available to caregivers. Healthcare workers were most commonly cited as the main sources of information; caregivers also received information from other caregivers in the community. Caregivers' motivations to seek MACV for their children were driven by personal awareness, engagements with trusted messengers, and perceived protective benefits of MACV against meningitis. Barriers to MACV and MCV2 uptake were linked to the unavailability of vaccines, immunization personnel not providing doses, knowledge gaps about the 15-18 month visit, practical constraints, past negative experiences, sociocultural influences, and misinformation, including misunderstanding about the need for MCV2. CONCLUSIONS: MACV and MCV2 uptake may be enhanced by addressing vaccination barriers and effectively communicating vaccination information and benefits through trusted messengers such as healthcare workers and other caregivers in the community. Educating healthcare workers to avoid withholding vaccines, likely due to fear of wastage, may help reduce missed opportunities for vaccination.
