Supporting evidence-based rotavirus vaccine introduction decision-making and implementation: Lessons from 8 Gavi-eligible countries.

Despite the 2009 World Health Organization recommendation that all countries introduce rotavirus vaccines (RVV) into their national immunization programs, just 81 countries had introduced RVV by the end of 2015, leaving millions of children at risk for rotavirus morbidity and mortality. In response, the Rotavirus Accelerated Vaccine Introduction Network (RAVIN) was established in 2016 to provide support to eight Gavi-eligible countries that had yet to make an RVV introduction decision and/or had requested technical assistance with RVV preparations: Afghanistan, Bangladesh, Benin, Cambodia, Democratic Republic of Congo, Lao People's Democratic Republic, Myanmar, and Nepal. During 2016-2020, RAVIN worked with country governments and partners to support evidence-based immunization decision-making, RVV introduction preparation and implementation, and multilateral coordination. By the September 2020 program close-out, five of the eight RAVIN focus countries successfully introduced RVV into their routine childhood immunization programs. We report on the RAVIN approach, describe how the project responded collectively to an evolving RVV product landscape, synthesize common characteristics of the RAVIN country experiences, highlight key lessons learned, and outline the unfinished agenda to inform future new vaccine introduction efforts by countries and global partners.

Addressing Immunization Inequity-What Have the International Community and India Learned over 35 Years?

Countries around the world established immunization programs over 40 years ago to reach all infants. The maturity of these preventive health programs offers some useful learning on the importance of, and components needed for, population-based services to reach all communities. A public health success, ensuring equity in immunization, requires a multi-faceted approach that includes sustained government and partner commitment and human, financial, and program operational resources. Evidence from India's Universal Immunization Program (UIP) across stabilizing vaccine supply and services, enhancing access, and generating demand for vaccines in the community provides a useful case study. The political leadership in India took advantage of the two decades of learning from polio eradication and focused initiatives, such as the National Health Mission and Intensified Mission Indradhanush, to reach populations with immunization services. With a goal of leaving no one behind, India's UIP and partners are bringing essential rotavirus and pneumococcal vaccines nationwide, upgrading vaccine cold chain and supply systems with technologies, such as the electronic Vaccine Intelligence Network (eVIN), and optimizing funding for local needs through the Program Implementation Plan (PIP) budgetary processes and building health worker capacities through training, awareness, and e-learning.

Empowering Health Workers to Build Public Trust in Vaccination: Experience from the International Pediatric Association's Online Vaccine Trust Course, 2020-2021.

BACKGROUND: The quality of interactions between health workers (HWs) and caregivers is key in vaccine acceptance. To optimize this, HWs need knowledge about best vaccine communication practices in person and on social media. Most pre-service curricula do not include such approaches. COVID-19 necessitated the International Pediatric Association (IPA) to shift from in-person train the trainer workshops to developing an online Vaccine Trust Course to address these gaps. METHOD: The seven-module, 8-hour Vaccine Trust Course was offered online in seven languages and promoted globally. Course outcomes for participants between September 1, 2020 and September 30, 2021 were assessed using enrollment, participation, and completion data; pre-and post-training surveys of attitudes, knowledge, and practice skills; and follow-up practice surveys 3 months post course completion. RESULTS: Of the 4,926 participants across 137 countries who registered; 2,381 (48.3 %) started the course, with 1,217 (51.1 %) completing. The majority were 25 - 39 years (57 %), female (57 %), and in pediatrics (70 %); 31 % came from India. 62 % of completers rated course structure/design as excellent, 36 % as good. Over 80 % rated the content as the most valuable aspect. Three months post training, 61 % HWs reported increased empathy towards caregivers, confidence while counseling and increased vaccine acceptance amongst their patients. 21 % identified the course as the only factor in these positive changes. CONCLUSION: Shifting from face-to-face to online training due to the COVID-19 pandemic helped increase the global reach of HWs course engagement and uptake. Trained HWs reported increased empathy towards caregivers and confidence while counseling and increased patient vaccine acceptance.

Key Factors Influencing Use of Immunization Cost Evidence in Country Planning and Budgeting Processes: Experiences From Indonesia, Tanzania, and Vietnam.

In many low- and middle-income countries, planning cycles and policy decisions are not always informed by cost evidence, even where relevant and recent cost evidence is available. The Immunization Costing Action Network (ICAN) project was a research and learning community designed to strengthen country capacity to generate immunization cost evidence and to understand and improve the evidence-to-policy linkages for the evidence. We identified key factors that increase the likelihood that health policy makers will use evidence for policy making or planning, which shaped the development of a 6-step evidence to policy and practice (EPP) facilitated process. ICAN used the EPP process in Indonesia, Tanzania, and Vietnam from 2016-2019. The experience resulted in several insights regarding country priorities related to cost evidence and factors that determine uptake. Cost evidence is more likely to be used if it answers a specific policy question prioritized by the immunization program, while the use case is less clear and urgent for routine planning and program management. Nonhealth ministries and subnational stakeholders can provide important perspectives to inform the research and its usability. The use case for evidence should be revisited periodically as divergences from formal planning cycles are common and new policy windows open. Ensuring evidence is available at the right time is critical, even if this requires a sacrifice between rigor and speed. Engaging a small group of stakeholders, rather than an individual, to champion the research may be more effective, and the research has greater legitimacy if it is produced by multidisciplinary country teams. Evidence and messages should be tailored for and packaged targeting different audiences. Going forward, continued support is necessary to bridge the divide between those who generate cost evidence and those who translate evidence for policy and planning decisions.

Integration of other services with human papillomavirus vaccination; lessons from earlier in the life course highlight the need for new policy and implementation evidence.

Integration of vaccination against human papillomavirus (HPV) with other essential health services for adolescents has been proposed in global strategies and tested in demonstration projects in low- and middle-income countries (LMIC). Published experiences, global guidance, and one key example, the implementation of "HPV Plus" in Tanzania, all demonstrate the need for greater operational evidence to guide future implementation and policy. Review of experiences earlier in the life course, integrating post-partum family planning with infant immunization, show lessons from 13 LMICs that can apply to provision of adolescent health information and services alongside HPV vaccination. Three distinct models of integration emerge from this review comprising: 1) multiple tasks and functions by health staff providing vaccination and other care, or 2) secondary tasks added to the main function of vaccination, or 3) co-location of matched services provided by different staff. These models, with strengths and weaknesses demonstrated in family planning and immunization experiences, apply in different ways to the three main platforms used for HPV vaccination: school, facility or community. For HPV vaccination policy and programming, an initial need is to combine the existing evidence on vaccine service delivery - including coverage, efficiency, cost, and cost-effectiveness information - with what is known on how integration works in practice; the operational detail and models employed. This synthesis may enable assessment which models best suit the different service delivery platforms. An additional need is to link this with more tailored local assessments of the adolescent burden of disease and other determinants of their well-being to develop new thinking on what can and cannot be done to integrate other services alongside HPV vaccination. New approaches placing adolescents at the center are needed to design services tailored to their preferences and needs. The potential synergies with cervical cancer screening and treatment for older generations of women, also require further exploration. Coordinated action aligning HPV vaccination with broader adolescent health and wellbeing will generate social, economic and demographic benefits, which in themselves are sufficient justification to devote more attention to integrated approaches.

Building and sustaining public and political commitment to the value of vaccination: Recommendations for the Immunization Agenda 2030 (Strategic Priority Area 2).

Vaccines have contributed to substantial improvements in health and social development outcomes for millions in recent decades. However, equitable access to immunization remains a critical challenge that has stalled progress toward improving several health indicators around the world. The COVID-19 pandemic has also negatively impacted routine immunization services around the world further threatening universal access to the benefits of lifesaving vaccines. To overcome these challenges, the Immunization Agenda 2030 (IA2030) focuses on increasing both commitment and demand for vaccines. There are three broad barriers that will need to be addressed in order to achieve national and subnational immunization targets: (1) shifting leadership priorities and resource constraints, (2) visibility of disease burden, and (3) social and behavioral drivers. IA2030 proposes a set of interventions to address these barriers. First, efforts to ensure government engagement on immunization financing, regulatory, and legislative frameworks. Next, those in subnational leadership positions and local community members need to be further engaged to ensure local commitment and demand. Governance structures and health agencies must accept responsibility and be held accountable for delivering inclusive, quality, and accessible services and for achieving national targets. Further, the availability of quality immunization services and commitment to adequate financing and resourcing must go hand-in-hand with public health programs to increase access to and demand for vaccination. Last, strengthening trust in immunization systems and improving individual and program resilience can help mitigate the risk of vaccine confidence crises. These interventions together can help ensure a world where everyone, everywhere has access to and uses vaccines for lifesaving vaccination.

Blended Learning Using Peer Mentoring and WhatsApp for Building Capacity of Health Workers for Strengthening Immunization Services in Kenya.

Evidence from available studies suggests that peer mentoring is a useful tool to build health workers' knowledge, skills, and practices. However, there is a dearth of research on use of this method of learning in immunization programs. Although WhatsApp has been used as a networking platform among health care professionals, there is limited research on its potential contribution to improving the immunization competencies of health workers. This study showed that peer mentoring and WhatsApp networking are useful blended learning methods for need-based and individualized capacity building of health workers providing immunization services. Future research to assess the comparative cost-benefit between classroom-based training and peer mentoring (along with WhatsApp networking) will be useful.

Using data to guide action in polio health communications: experience from the Polio Eradication Initiative (PEI).

Health communication is increasingly considered a priority element of investments and interventions intended to improve personal and public health (Piotrow et al., 1997). But a prevailing focus in health communication on information, education, awareness, and knowledge--and their assumed relation to changing behaviour among target individuals or households--can underestimate the complexity of wider ecological conditions that influence and limit individual, household, and even community choices and capacity to choose. Experience from the Polio Eradication Initiative (PEI)--drawing on evidence from the India and Nigeria country programmes--provides some insights into how the health communication interventions can be strengthened through the adoption of a more holistic ecological model of people and their health-related behaviours analysed in the context of larger social, economic, political, and cultural forces (see, for example, Kelly et al., 2008). In particular, polio eradication health communication offers useful lessons in the importance of generating and using data of sufficient quality to enable a more ecological analysis--combining and measuring specific communication inputs and epidemiological "outputs."

Communication for polio eradication: improving the quality of communication programming through real-time monitoring and evaluation.

Communication is a critical component in assuring that children are fully immunized and that simultaneous immunity is attained and maintained across large geographic areas for disease eradication and control initiatives. If service delivery is of good quality and outreach to the population is active, effective communication--through advocacy, social mobilization, and program communication (including behavior change activities and interpersonal communication)--will assist in raising awareness, creating and sustaining demand, preventing or dispelling misinformation and doubts, encouraging acceptance of and participation in vaccination services, more rapid reporting of disease cases and outbreaks, and mobilizing financial resources to support immunization efforts. There is evidence of 12% to 20% or more increases in the absolute level of immunization coverage and 33% to 100% increases in relative coverage compared to baselines when communication is included as a key component of immunization strengthening. This article utilizes evidence from Afghanistan, India, Pakistan, and Nigeria to examine how the Global Polio Eradication Initiative has utilized monitoring and evaluation data to focus and improve the quality and impact of communication activities.

Use of cellular phone contacts to increase return rates for immunization services in Kenya.

INTRODUCTION: In Kenya, failure to complete immunization schedules by children who previously accessed immunization services is an obstacle to ensuring that children are fully immunized. Home visit approaches used to track defaulting children have not been successful in reducing the drop-out rate. METHODS: This study tested the use of phone contacts as an approach for tracking immunization defaulters in twelve purposively-selected facilities in three districts of western Kenya. For nine months, children accessing immunization services in the facilities were tracked and caregivers were asked their reasons for defaulting. RESULTS: In all of the facilities, caregiver phone ownership was above 80%. In 11 of the 12 facilities, defaulter rates between pentavalent1 and pentavalent3 vaccination doses reduced significantly to within the acceptable level of < 10%. Caregivers provided reliable contact information and health workers positively perceived phone-based defaulter communications. Tracking a defaulter required on average 2 minutes by voice and Ksh 6 ($ 0.07). Competing tasks and concerns about vaccinating sick children and side-effects were the most cited reasons for caregivers defaulting. Notably, a significant number of children categorised as defaulters had been vaccinated in a different facility (and were therefore "false defaulters"). CONCLUSION: Use of phone contacts for follow-up is a feasible and cost-effective method for tracking defaulters. This approach should complement traditional home visits, especially for caregivers without phones. Given communication-related reasons for defaulting, it is important that immunization programs scale-up community education activities. A system for health facilities to share details of defaulting children should be established to reduce "false defaulters".

Immunization review meetings: "Low Hanging Fruit" for capacity building and data quality improvement?

INTRODUCTION: Although systematic program review meetings are common practice in many health and immunization programs, there is little documentation on their implementation and role. Adult education principles espouse opportunities for peer exchange to build capacity and cross-learning, for which review meetings have been a forum utilized in immunization programs for many years. This study describes the process and use of review meetings to build immunization technical capacity in four African countries since 2011. METHODS: A longitudinal case study providing retrospective descriptive analysis and qualitative data collected on immunization program implementation and review meetings conducted within the years of 2011-2016 with district and facility health staff and technical partners from Ethiopia, Kenya, Tanzania and Uganda. RESULTS: Based on summarized findings and analyses from over 200 review meetings conducted in the four countries within the time period of 2011-2016, these meetings have been shown to be effective tools for improving immunization program performance and the capacity of health staff. CONCLUSION: Review meetings (ideally conducted quarterly) provide health workers with beneficial and low cost opportunities for adult learning, including building skills in data analysis and review, which can be sustained at district and health facility levels. In combination with other performance improvement approaches implemented and supported in countries (such as supportive supervision, training, and on-the-job learning and assessment), review meetings can also contribute to achievement of immunization and health outcomes.
