Introduction of the pneumococcal conjugate vaccine in humanitarian and fragile contexts: Perspectives from stakeholders in four African countries.

Childhood pneumonia causes a significant burden of preventable child morbidity and mortality in Chad, Guinea, Somalia/Somaliland, and South Sudan. Leaders from these countries have committed to reducing this burden and are preparing to introduce the pneumococcal conjugate vaccine (PCV) into their immunization programs. To support long-term sustainability for expected PCV introductions in settings afflicted by prolonged humanitarian crises this research explores national stakeholders' perspectives on contextual factors that may influence optimal vaccine implementation. This qualitative study used purposive sampling to identify and interview stakeholders involved in vaccine decision-making. Interview transcripts were analyzed through the framework method, an approach involving charting data into pre-populated matrices. Findings from interviews with 16 key informants from government, partner organizations, and international health agencies fit within the following four overarching themes: (1) population-level vulnerabilities to pneumonia, exacerbated by climatic risks and low levels of maternal education; (2) disease burden and the interest in enhancing surveillance to monitor vaccine impact and integrate disease control efforts; (3) policy processes, including formalizing vaccine decision-making; and (4) vaccine implementation preparation, including the conduct of robust communication campaigns, training, and cold chain upgrades. This research explores perspectives from leaders in these countries which are at pivotal moments in their journeys toward introducing PCV. Widespread commitment among leaders, in addition to financial support, will facilitate vaccine introduction. Further, fostering a shared understanding among partners about context-specific determinants of program success will help build tailored implementation strategies for each country.

Closing the pneumococcal conjugate vaccine (PCV) introduction gap: an archetype analysis of last-mile countries.

BACKGROUND: Pneumonia remains the leading infectious cause of global childhood deaths, despite the availability of pneumococcal conjugate vaccine (PCV) products and widespread evidence of their safety and efficacy. OBJECTIVE: To map the landscape of countries that are yet to fully include PCV in their National Immunization Programs, we conducted an archetype analysis of country indicators related to barriers and facilitators for PCV decision-making. METHODS: We created a country matrix focused on three key domains - health characteristics, immunisation factors, and policy framework, and identified ten related indicators. We scored countries based on indicator performance and subsequently ranked and grouped them into three archetypes of low-, moderate-, and high-barrier countries with regard to PCV introduction. RESULTS: Our results indicated 39 countries (33 low- and middle-income countries [LMICs] and 6 high-income countries) that are yet to introduce PCV. Among LMICs, 15 countries were classified as 'low-barrier,' indicating factors favourable for PCV introduction such as high immunisation coverage of common childhood vaccines, supportive governments, and substantial disease burden and eligibility for Gavi support. Countries classified in the 'moderate-barrier' (12) and 'high-barrier' (6) archetypes demonstrated adequate capacity in immunisation systems but had competing national priorities and cost barriers that impeded policy decision-making on PCV introduction. CONCLUSIONS: The current health and policy indicator-based categorisation provides an actionable framework to design tailored PCV advocacy within these last-mile countries. Policy approaches emerging from this framework can lead to strengthened decision-making on vaccine introduction and sustained vaccine access that can enhance child survival worldwide.

Exploring beliefs and experiences underlying self-stigma among sex workers in Hanoi, Vietnam.

Sex workers are among the most stigmatised people globally, with sex workers in Vietnam being no exception. Self-stigma affects sex workers adversely, harming psychological health and acting as a barrier to seeking health care. To inform programmes and interventions to improve well-being, identifying unhelpful or negative core beliefs may provide the basis from which individuals can be supported. With this in mind, this study aimed to gain the perspective of sex workers in Vietnam on the contexts of their working lives. Data were collected in Hanoi. Fourteen semi-structured interviews were conducted with Vietnamese sex workers over the age of 18 who were working or formerly worked in Vietnam. Data were analysed manually, informed by theoretical models of self-stigma using inductive thematic analysis. The analysis identified negative/unhelpful core beliefs (disclosure, self-stigma and shame, sexuality, sexual pleasure relationships, health care); contextual life circumstances (sex work, violence, traditional education); and coping mechanisms (problem-focused coping, emotion-focused coping). Findings identify the importance of core beliefs in understanding self-stigma, paving the way for programmes and interventions to address self-stigma among sex workers.
