Despite global commitments to universal health coverage, persons with disabilities (PwD) continue to face significant barriers in accessing appropriate healthcare, including diagnostics, treatments and preventive healthcare, with lower participation in cancer screening and vaccination programs. These disparities are driven by diverse, intersecting obstacles (structural, financial, communicative, and social) that vary by disability type and context. Inclusive approaches, co-designed with PwD and supported by standardized assessment tools, are urgently needed to address persistent inequities in healthcare access and outcomes. Full article

Background: Human papillomavirus (HPV) is the most prevalent sexually transmitted infection with significant health implications, especially for women living with human immunodeficiency virus (HIV). The variability in reported prevalence and genotype distribution of HPV among HIV-positive women across different regions in Africa necessitates a comprehensive and systemic examination. Methods: A systematic search was conducted across several databases. A random effect model was used to evaluate study heterogeneity through Q statistics and I² measures. Publication bias was assessed using funnel plots and Egger’s tests. Risk factors for HPV among HIV-positive women were summarized qualitatively. This review was registered with PROSPERO: CRD42024525123. Result: Twenty-three studies involving 9954 HIV-positive women were combined to estimate HPV prevalence. The overall prevalence of all HPV types was 49.4% (95% CI: 42.43, 56.38), with evidence of heterogeneity (Q = 520.92, df = 16, I² = 96.93%, p < 0.0001). The prevalence of high-risk HPV was 45.26% (95% CI: 31.02, 59.91), showing heterogeneity across studies (Q = 439.18, df = 10, p < 0.0001, I² = 97.72%). Low-risk HPV had a prevalence of 24.98% (95% CI: 12.27, 40.41), with variation among studies (Q = 134.39, df = 6, p < 0.0001, I² = 95.54%). The most frequent genotypes were 16, 18, 52, 33, and 35. A higher cluster of differentiation 4 (CD4) count is associated with a lower prevalence of HPV. Conclusions: The pooled HPV prevalence among HIV-positive women in Africa is lower compared to previous studies, but the slow decline poses challenges to meet the WHO’s goal of eliminating HPV-related cervical cancer by 2030. Therefore, enhanced prevention efforts, including HPV self-sampling, improved vaccination coverage, and early treatment interventions, are essential to meet the goal of eliminating HPV-related cervical cancer.

Background: Hansen’s disease or leprosy is one of the 21 neglected tropical diseases (NTDs). In Ecuador, leprosy is considered eliminated as a public health problem; however, new cases are reported annually. Additionally, Mycobacterium leprae infection was detected in nine-banded armadillos across the country, suggesting a potential zoonotic reservoir. This literature review aims to provide an updated overview of the epidemiological situation of leprosy in Ecuador, identify knowledge gaps, and outline research priorities to support the development of a comprehensive national strategy for achieving zero autochthonous cases. Methods: This article analyses the current situation of leprosy in Ecuador based on international and national publications. A retrospective literature search using five international, regional, and national publications on leprosy published between 1954 and 2024 (70 years) with no restriction on language or publication date, was performed. Findings: Our review identified 28 publications with the earliest article dating back to 1954. Of these, 14 were published in international journals, 15 (53.6%) were in Spanish. Four nationwide studies documented leprosy cases across Ecuador’s three continental regions (Coast, Andes, and Amazon) with a predominance in the tropical coast. No cases have been reported from the Galápagos Islands. From 1983, Ecuador started multi-drug therapy. Data from the Ministry of Public Health (MoH) system identified 1539 incident cases, showing a significant decline in new cases from 2000 to 2024, with no cases in children. New cases detection rate by 100,000 inhabitants was 0.51 in 2019 according to the World Health Organization (WHO). No study has genotyped the Mycobacterium spp. in human cases, other animal species, or environment. According to the MoH, multibacillary leprosy accounts for 78.95% of diagnosed cases, with confirmation based on Ziehl–Neelsen staining and histopathology. No survey has assessed disabilities, knowledge, attitudes, and practices (KAP) or stigma related to leprosy. Research is needed on transmission routes, Mycobacterium genotyping, genetic susceptibility, and antibiotic resistance. BCG vaccination coverage fell to 75.3% in 2021. Cases are currently diagnosed and treated on an outpatient basis in large hospitals. Conclusions: This comprehensive review highlights persistent gaps in leprosy research and critical information, despite seven decades of documented cases in Ecuador. The disease is still endemic across the country, particularly at subnational level in the subtropics and tropics of the Pacific coast and the Amazon. There is a need for nationwide epidemiological research on reservoirs and the environment applying the One Health concept. Increased laboratory facilities and readily available official data are required to improve our understanding of leprosy in Ecuador. Strengthening community-level efforts is essential for Ecuador to meet the targets of the “WHO’s Towards Zero Leprosy: Strategy 2021–2030.” Full article

Background/Objectives: Booster vaccination coverage in the adult population in Poland remains insufficient. The objective of this study was to utilize the opportunity of a visit to the Regional Blood Transfusion Center in Wroclaw—associated with blood donation—as a means to remind individuals about the need for tetanus booster vaccination and to assess tetanus immunity in healthy adults (30–40 years after their last mandatory dose) who had not received booster immunizations. Materials and Methods: A total of 97 blood donors aged 50 to 64 years (median age: 54 years) were enrolled, of whom 78% were male. 1. Tetanus immunity was assessed by a single measurement of serum anti-tetanus IgG antibody concentration. 2. A questionnaire was used to collect data relevant to tetanus immune status. 3. Individuals with insufficient protection received a booster dose of the tetanus vaccine, and the post-vaccination serologic response was evaluated. Results: 1. In the study group, 10.3% of participants had no protective immunity against Clostridium tetani, while 5.2% exhibited uncertain protection. An additional 32% demonstrated antibody levels conferring only short-term protection. Satisfactory protection—defined as immunity lasting at least 3 years—or long-term protection (at least 5 years) was identified in 52.5% of patients. Although 72% of donors reported receiving mandatory childhood immunizations, only 5% could provide medical documentation. In this subgroup, a significantly higher geometric mean antibody concentration was observed (0.69 vs. 0.52 IU/mL; p = 0.04), and significantly fewer participants required immediate post-exposure prophylaxis (1/39 vs. 14/54; p = 0.003). 2. Among the 46 individuals eligible for a booster dose, 17 (37%) returned for vaccination. Of these, 16 (94%) achieved antibody titers consistent with long-term protection following a single vaccine dose. Conclusions: Tetanus immunity among adults is heterogeneous and difficult to predict due to the frequent lack of vaccination records and unreliable self-reported histories. A history of injury and associated surgical wound care involving injection often serves as the only indication of prior vaccination. A single booster dose is highly effective in eliciting a robust immune response in individuals vaccinated during childhood but lacking recent boosters. Rising vaccine hesitancy toward both mandatory and recommended immunizations in Poland negatively influences adult decisions regarding tetanus vaccination. Participation in voluntary blood donation programs presents a valuable opportunity for immunization education, immune status screening, and the implementation of effective catch-up vaccination strategies.

Background: The COVID-19 pandemic exposed major structural deficiencies in global health governance, including stark inequities in vaccine access, intervention timing, and mortality outcomes. While economic resources played a role, the influence of governance performance remains insufficiently examined. This study addresses a significant gap by integrating governance metrics with pandemic response data to assess how governance quality, independent of income level, affected national outcomes. Although the Oxford COVID-19 Government Response Tracker (OxCGRT) dataset has been widely used to document policy responses, this study offers a novel contribution by linking these policy interventions with governance performance and evaluating their joint effect on health outcomes and vaccine equity. Methods: This mixed-methods study combines quantitative analysis of global datasets with a qualitative literature review. Quantitative data were mainly obtained from the Oxford COVID-19 Government Response Tracker (OxCGRT), the World Bank’s Worldwide Governance Indicators (WGIs), and World Bank/WHO databases. A governance performance index was constructed using two WGI components: Government Effectiveness and Regulatory Quality. Countries were grouped into high, medium, or low governance categories. Statistical tests included ANOVA, Kaplan Meier survival analysis, and multivariable OLS regression. The qualitative component reviewed 45 academic and institutional sources on governance performance during COVID-19. Results: Countries with high governance performance had earlier public health interventions, lower mortality, and broader vaccine coverage, independent of income level. Kaplan Meier analysis revealed faster school closures in these countries (p < 0.01). Multivariable regression showed governance remained a significant predictor after adjusting for income and health spending. Qualitative findings highlighted recurring weaknesses in legal enforceability, intergovernmental coordination, and global financing mechanisms. Conclusions: Governance performance had a decisive impact on pandemic outcomes. The COVID-19 crisis revealed the need for robust governance systems capable of responding to complex emergencies that extend beyond the health sector into institutional, economic, and social spheres.

Background/Objectives: DTP3 (diphtheria–tetanus–pertussis vaccine, third dose) coverage is a key indicator of the strength and continuity of routine immunization programs, which demonstrably reduces the burden of infectious diseases globally. This study aims to assess trends in DTP3 vaccination coverage across Asian regions and countries from 2012 to 2023, focusing on changes associated with the COVID-19 pandemic. Methods: DTP3 vaccination data were obtained from official WHO/UNICEF Estimates of National Immunization Coverage (WUENIC) and analyzed using Joinpoint regression to detect statistically significant changes in vaccination trends. Data were grouped by five Asian subregions based on the UN geoscheme (Central, Eastern, Southeastern, Southern, and Western Asia), and trends were weighted using birth cohort sizes. The presence of joinpoints and annual percentage changes (APCs) was calculated, and potential pandemic-related disruptions were contextualized. Results: At the continental level, Asia experienced a modest 0.4% annual increase in DTP3 coverage between 2012 and 2023, with a significant joinpoint detected in 2018. Following this, Southeast Asia’s coverage declined at an annual rate of −4.32% before beginning to recover in 2021, while South Asia showed a similar pattern. Country-level analysis revealed significant heterogeneity, with a comparison between 2019 and 2023 showing profound post-pandemic declines in some nations, such as Lebanon (–21%) and Myanmar (–9.4%), while others, like Iraq and the Philippines, achieved substantial recoveries with coverage increasing by over 6 percentage points. These trends contrasted with persistent declines in fragile states (e.g., Afghanistan, Yemen) and sustained high coverage in others (e.g., Bangladesh, Israel). The pandemic, systemic weaknesses, emerging vaccine hesitancy, and misinformation were identified as key influences. Conclusions: There is progress in DTP3 coverage across Asia. There were pandemic-related disruptions, particularly in regions with fragile health systems. Strategies to address zero-dose and dropout children, improve service continuity, and counter misinformation are essential to meet immunization targets under the Immunization Agenda 2030.

Out-of-pocket expenditure (OOPE) comprises 62% of national health expenditure in India. This heavy reliance on direct payments has engendered economic vulnerability and catastrophic financial pressures (typically defined as out-of-pocket spending exceeding a certain threshold of household income, leading to financial hardship) on households in a country where public health spending remains below targeted levels. The onset of the COVID-19 pandemic intensified these financial hardships further, as both total healthcare spending and OOPE experienced significant escalations due to the increased need for emergency care, vaccination efforts, and expanded health infrastructure. A retrospective, single-center study was conducted using data from COVID-19 patients admitted between June 2020 and June 2022. Patient data were collected from the Medical Records, IT, and Finance departments. A validated proforma was used for data extraction. Descriptive statistics were calculated, and the Shapiro–Wilk test was applied to assess normality of billing and OOPE data. Patients were stratified into three groups based on their insurance status, allowing for comparative analysis of OOPE percentages and absolute expenditures. The 2715 COVID-19 patients were categorized into three groups according to their health financing: those covered under AB-PMJAY (42.76%), private health insurance (22.16%), and the uninsured (35%). While the median billing amounts were comparable across these groups (ranging between INR 85,000 and INR 90,000), a substantial disparity was observed in terms of financial burden. All patients covered under AB-PMJAY incurred no OOPE, whereas privately insured patients had a median OOPE that constituted approximately 21% of their total billing amounts, with significant variability among different insurers. The uninsured group represented 35% of the cases and experienced the highest median OOPE, indicating substantial financial risk. The COVID-19 pandemic has revealed critical gaps in India’s health financing framework. This study emphasizes the strong financial protection provided by AB-PMJAY, while also exposing the limitations of private health insurance in shielding patients from substantial healthcare costs. As the country progresses toward universal health coverage, there is a pressing need to expand public health insurance schemes that are inclusive, equitable, and effectively implemented. Additionally, strengthening regulation and accountability in the private insurance sector is essential. The study findings reinforce that AB-PMJAY has been highly successful in reducing OOPE and enhancing financial risk protection. Although private insurance reduced OOPE, patients still faced considerable expenses. The stark difference in OOPE of 100% for uninsured patients, 21.16% for privately insured, and 0% for AB-PMJAY beneficiaries underscores the importance of further expanding AB-PMJAY to reach more vulnerable populations.

Background: Vaccinations are crucial for preventing infectious diseases. Parental knowledge and attitudes significantly impact vaccination decisions. Methods: This study analyzed parental knowledge and opinions on childhood vaccinations (focus: measles, pertussis) and assessed vaccination coverage rates in Radomsko, Poland. A cross-sectional study (Jan–Mar 2025) combined the following: (1) parent questionnaires (children aged 6–11 years), including opinions based on the validated VAX scale and (2) analysis of official vaccination coverage data (sanitary inspection). Statistical analysis included descriptive statistics and logistic regression; results are presented as odds ratios (OR). Results: A total of 459 parents participated (mean age 38.9 years, 95% female, 67% Master’s-level education). Conclusions: Most correctly identified measles (92%) and pertussis (85%) vaccines as mandatory. Considerable confusion existed about newer mandatory vaccines and varicella (78% incorrectly thought mandatory). Analysis revealed the influence of both knowledge and opinions from the VAX scale on vaccination decisions. Higher parental education significantly increased vaccination adherence for pertussis (OR = 2.03; p < 0.001) and both diseases (OR = 1.83; p < 0.001). While general vaccination awareness was high (97%), detailed knowledge of Poland’s mandatory schedule was alarmingly low, especially for newer vaccines. Parental education level is a key determinant of both accurate knowledge and vaccination compliance. Targeted educational interventions are urgently needed to improve parental understanding and support public health goals. Full article

Background/Objective: To assess vulnerable Romanian children’s knowledge, attitudes, and beliefs regarding the HPV vaccination. Methods: Vulnerable children (ethnic minorities, high social vulnerability index, or low socioeconomic status) from three schools in Cluj County, Romania, were enrolled in a short educational presentation regarding HPV and were delivered a physical questionnaire consisting of 26 items. Results: 199 vulnerable school students concluded the questionnaire with a mean age of 14.62. Most participants were unaware of the HPV infection or the HPV vaccine. Following the educational program, most participants exhibited a reasonably elevated level of knowledge, which positively correlated with the intention to vaccinate. Fifty-three per cent of respondents would vaccinate in school if the vaccine were available, fifty-four per cent would vaccinate if the product were free of charge or at minimal cost, and over sixty-four per cent would vaccinate at their doctor’s recommendation. Several knowledge items, beliefs, and attitudes towards vaccination were disclosed to influence children’s preference to participate in vaccination campaigns. Conclusions: This analysis unveiled the pivotal role of knowledge about HPV in the immunization uptake within underserved, vulnerable populations of Romanian children. An intricate interplay between vulnerability, knowledge, accessibility, and the willingness to vaccinate was impacted by several beliefs and attitudes towards HPV vaccination. Most children were willing to participate in HPV immunization campaigns, whether school-based, reimbursed, or at the doctor’s recommendation. These findings act as pillars for assembling future educational campaigns in vulnerable Romanian communities of children, aiming to enhance awareness and coverage of HPV vaccination and ensure inclusive health policies.

Background: The COVID-19 pandemic magnified long-standing health disparities in the United States, particularly among rural, disadvantaged populations. These communities experience greater barriers to healthcare access, a higher prevalence of chronic illness, and increased vaccine hesitancy factors that collectively contribute to poorer health outcomes. Methods: This narrative review examines rural–urban disparities in COVID-19 vaccine uptake and their impact on mortality, with a focus on cardiovascular disease (CVD) outcomes. We synthesized the peer-reviewed literature, CDC data, and U.S. Census reports to assess factors contributing to vaccine hesitancy, vaccination coverage, COVID-19-related mortality, and CVD mortality trends. Results: Rural residents were less likely to initiate COVID-19 vaccination, showed greater vaccine hesitancy, and experienced higher rates of both COVID-19 and CVD mortality. These disparities were further driven by safety concerns surrounding mRNA technology, misinformation, infrastructural barriers, and sociodemographic factors including political affiliation, education, poverty, and religion. Notably, pre-existing CVD increased vulnerability to severe COVID-19 outcomes in rural communities. Conclusions: Expanding vaccination efforts and improving healthcare infrastructure are essential for addressing these widening health inequities. Future public health strategies should prioritize culturally tailored interventions and rural-specific outreach to reduce vaccine hesitancy and improve mortality outcomes in underserved populations.

Background: Vaccination is a crucial public health measure to control infectious diseases, including seasonal influenza. Yet, vaccine uptake varies globally due to sociodemographic factors, misinformation, and access disparities. Objectives: The objective of this study was to assess the prevalence and sociodemographic factors associated with vaccination and the main reasons for vaccine hesitancy in Albania. Methods: A cross-sectional study, conducted in Albania in November–December 2021, included a sample of 1302 individuals aged ≥18 years (≈57% females; mean age: 38.3 ± 15.0 years; response rate: ≈87%). A structured questionnaire was administered inquiring about co-vaccination status against seasonal influenza and COVID-19, reasons for not being vaccinated, and sociodemographic characteristics of participants. Binary logistic regression was used to assess the association of co-vaccination status with sociodemographic factors. Results: Overall, about 28% of individuals were co-vaccinated against seasonal influenza and COVID-19 at least with one dose (25% in males vs. 29% in females; 22% among 18–24-year-olds vs. 54% among those aged ≥65 years). Independent positive and significant correlates of being co-vaccinated included older age (OR = 7.0, 95%CI = 3.7–12.9) and a higher educational attainment (OR = 2.3, 95%CI = 1.4–3.6). The main reasons for vaccine hesitancy among non-vaccinated individuals included the belief that vaccines are: harmful (72%), not effective (66%), weaken the immune system (58%), are not safe (56%), and preference to recover naturally (52%). Conclusions: This study evidenced a relatively low co-vaccination rate in Albania with significant sociodemographic disparities, notwithstanding the availability of vaccines and their free-of-charge provision to the overall population. Older age and higher educational attainment were identified as independent positive predictors of co-vaccination uptake, suggesting the need for targeted public health strategies to address vaccine hesitancy, particularly among younger and less-educated population categories. Our findings emphasize the importance of tailored communication campaigns and community-based interventions to improve vaccine coverage and mitigate the impact of infectious diseases in Albania and elsewhere.

Background: Varicella remains a prevalent vaccine-preventable disease, but breakthrough infections are increasingly reported. However, long-term, population-based studies investigating the temporal and demographic characteristics of breakthrough varicella remain limited. Methods: This retrospective study analyzed surveillance data from Jinhua City, China, from 2016 to 2024. Varicella case records were obtained from the China Information System for Disease Control and Prevention (CISDCP), while vaccination data were retrieved from the Zhejiang Provincial Immunization Program Information System (ISIS). Breakthrough cases were defined as infections occurring more than 42 days after administration of the varicella vaccine. Differences in breakthrough interval were analyzed across subgroups defined by dose, sex, age, population category, and vaccination type. A bivariate cubic regression model was used to assess the combined effect of initial vaccination age and dose interval on the breakthrough interval. Results: Among 28,778 reported varicella cases, 7373 (25.62%) were classified as breakthrough infections, with a significant upward trend over the 9-year period (p < 0.001). Most cases occurred in school-aged children, especially those aged 6–15 years. One-dose recipients consistently showed shorter breakthrough intervals than two-dose recipients (M = 62.10 vs. 120.10 months, p < 0.001). Breakthrough intervals also differed significantly by sex, age group, population category, and vaccination type (p < 0.05). Regression analysis revealed a negative correlation between the initial vaccination age, the dose interval, and the breakthrough interval (R² = 0.964, p < 0.001), with earlier and closely spaced vaccinations associated with longer protection. Conclusions: The present study demonstrates that a two-dose varicella vaccination schedule, when initiated at an earlier age and administered with a shorter interval between doses, provides more robust and longer-lasting protection. These results offer strong support for incorporating varicella vaccination into China’s National Immunization Program to enhance vaccine coverage and reduce the public health burden associated with breakthrough infections.

Background/Objectives: The whole cell pertussis vaccine was introduced in the United States in the 1940s and switched to the acellular pertussis vaccine partially in 1992 and completely in 1997. This study examines the relationship between the resurgence of pertussis in the United States and the change in the type of pertussis vaccines. Methods: Pertussis cases from 1922 to 2024 were obtained from the CDC’s national notifiable disease surveillance system, and vaccination coverage was obtained from the WHO. A trend analysis and Pearson’s correlation test were conducted between the incidence of cases and the coverage of the third and fourth doses of the pertussis vaccine. An ANOVA test and multivariable linear regression were performed to assess the association between the type of vaccine and the number of pertussis cases. Results: The number of cases increased from 4083 in 1992 to 35,435 in 2024, with cyclical outbreaks in 2010, 2012–2014, and 2024. The third and fourth doses of pertussis vaccine coverage had mild and moderate correlations with the number of pertussis cases. The vaccine type had a significant association with the number of pertussis cases and stayed significant after adjusting for vaccination coverage. Conclusions: The switch in pertussis vaccine has impacted the epidemiology of pertussis outbreaks in the United States. A combination of factors, such as different types of immune response to vaccines, waning of immunity, and selection of non-vaccine bacterial strains, may explain the observed results. Further research on newer, improved vaccinations or alternative schedules in children needs to be conducted to address the resurgence of pertussis in this study. Full article

Background/Objectives: Mumps remains a relevant vaccine-preventable disease globally, especially in settings where immunization coverage fluctuates or vaccine-induced immunity wanes. This study aimed to assess long-term trends in mumps incidence, vaccination coverage, clinical outcomes, and demographic characteristics in the Autonomous Province of Vojvodina (AP Vojvodina), Serbia, over a 47-year period. Methods: We conducted a retrospective observational study using surveillance data from the Institute of Public Health of Vojvodina. Analyses included annual mumps incidence rates (1978–2024), coverage with mumps-containing vaccines (MuCVs; 1986–2024), monthly case counts, and individual-level case data for the 1997–2024 period. Variables analyzed included age, month of notification, gender, vaccination status, presence of clinical complications, and the method used for case confirmation. Results: Following the introduction of MuCV in 1986, the mumps incidence markedly declined, with limited resurgences in 2000, 2009, and 2012. Between 1997 and 2024, a total of 1358 cases were reported, with 62.7% occurring in males. Over time, the age distribution shifted, with adolescents and young adults being increasingly affected during the later (2011–2024) observed period. In 2012, the highest age-specific incidence was observed among individuals aged 10–19 and 20–39 years (49.1 and 45.5 per 100,000, respectively). Vaccination coverage for both MuCV doses was suboptimal in several years. The proportion of unvaccinated cases decreased over time, while the proportion with unknown vaccination status increased. Mumps-related complications—such as orchitis, pancreatitis, and meningitis—were rare and predominantly affected unvaccinated individuals: 84.2% of orchitis, 40.0% of pancreatitis, and all meningitis cases. Only two pancreatitis cases (40.0%) were reported after one MMR dose, while fully vaccinated individuals (two doses) had one orchitis case (5.3%) and no other complications. Laboratory confirmation was applied more consistently from 2009 onward, with 49.6% of cases confirmed that year (58 out of 117), and, in several years after 2020, only laboratory-confirmed cases were reported, indicating improved diagnostic capacity. Conclusions: Despite substantial progress in controlling mumps, gaps in vaccine coverage, waning immunity, and incomplete vaccination records continue to pose a risk for mumps transmission. Strengthening routine immunization, ensuring high two-dose MuCV coverage, improving vaccination record keeping, and enhancing laboratory-based case confirmation are critical. Consideration should be given to booster doses in high-risk populations and to conducting a seroepidemiological study to estimate the susceptible population for mumps in AP Vojvodina. Full article

Despite growing global momentum to reduce the number of children who never received a dose of any vaccine, i.e., zero-dose (ZD) children, persistent geographic and social inequities continue to undermine progress toward universal immunization coverage. In Madagascar, where routine vaccination coverage remains below 50% in most regions, the non-governmental organization Doctors for Madagascar and public sector partners are implementing the SOAMEVA program: a targeted community-based initiative to identify and reach ZD children in sixteen underserved districts in the country’s south. This paper outlines the equity-sensitive evaluation design developed to assess the implementation and impact of SOAMEVA. It presents a forward-looking evaluation framework that integrates both quantitative program monitoring and qualitative community insights. By focusing at the fokontany level—the smallest administrative unit in Madagascar—the evaluation captures small-scale variation in ZD prevalence and program reach, allowing for a detailed analysis of disparities often masked in aggregated data. Importantly, the evaluation includes structured feedback loops with community health workers and caregivers, surfacing local knowledge on barriers to immunization access and program adoption. It also tracks real-time adaptations to implementation strategy across diverse contexts, offering insight into how routine immunization programs can be made more responsive, sustainable, and equitable. We propose eight design principles for conducting equity-sensitive evaluation of immunization programs in similar fragile settings. Full article
