Subnational inequalities have received limited attention in the monitoring of progress towards national and global health targets during the past two decades. Yet, such data are often a critical basis for health planning and monitoring in countries, in support of efforts to reach all with essential interventions. Household surveys provide a rich basis for interventions coverage indicators on reproductive, maternal, newborn and child health (RMNCH) at the country first administrative level (regions or provinces). In this paper, we show the large subnational inequalities that exist in RMNCH coverage within 39 countries in sub-Saharan Africa, using a composite coverage index which has been used extensively by Countdown to 2030 for Women's, Children's and Adolescent's Health. The analyses show the wide range of subnational inequality patterns such as low overall national coverage with very large top inequality involving the capital city, intermediate national coverage with bottom inequality in disadvantaged regions, and high coverage in all regions with little inequality. Even though nearly half of the 34 countries with surveys around 2004 and again around 2015 appear to have been successful in reducing subnational inequalities in RMNCH coverage, the general picture shows persistence of large inequalities between subnational units within many countries. Poor governance and conflict settings were identified as potential contributing factors. Major efforts to reduce within-country inequalities are required to reach all women and children with essential interventions.

BACKGROUND: Hepatitis B virus (HBV) immunisation is the first vaccine of infant life and one of the most commonly refused immunisations on the Australian Immunisation Schedule. AIMS: To quantify the frequency of declined HBV immunisation birth-doses, investigate reasons for refusal, and determine information sources used by parents. MATERIALS AND METHODS: A cross-sectional study using a questionnaire was conducted on postnatal women who declined their newborn's HBV birth-dose immunisation during December 2016-July 2017 at an Australian tertiary referral hospital. Mothers who were non-English-speaking, unwell or medically unstable, or otherwise unavailable were excluded. RESULTS: One hundred and thirty-seven of the 1574 (8.7%) eligible reviewed infants had HBV immunisation birth-doses documented as declined; 113 mothers consented to complete the questionnaire. The most common reasons for declining the dose were: 'baby too young' (55.8%); preference for two, four and six-month HBV immunisations only (56.6%); perceived low risk of contracting HBV (45.1%); and a fear of 'overloading' their baby's immune system (42.5%). General practitioners or nurses/midwives (43.3%) and the internet/media (33.6%) were the predominant information sources consulted, and 58.4% felt satisfied with the information they received antenatally. Eighty-eight of 113 mothers (77.9%) would still consider future immunisations for their infant. CONCLUSIONS: The majority of postnatal women decline HBV birth-dose immunisation for their newborns citing age-related safety concerns and vaccine misconceptions. Informal information sources such as the internet and media are often consulted. Addressing the need for antenatal and health professional education toward the birth-dose may be instrumental in improving uptake.

Background: Vaccination is one of the most effective public health interventions to prevent infectious diseases among children. However, vaccination coverage rates are lower among underserved pediatric populations because of barriers including lack of access to healthcare, socioeconomic factors, lack of health literacy, and logistical issues. Objective: To assess the impact of community-based interventions on vaccine coverage in underserved pediatric populations and to determine the major factors driving vaccine uptake. Methodology: A longitudinal community intervention study in 25 underserved communities in 2022-2025 with 4,500 children aged 0-14 years. Intervention strategies involved community health education, mobile vaccination clinics, digital reminder systems, and local stakeholder engagement. Descriptive statistics, logistic regression and trend analysis were used to analyze vaccination records, household surveys and healthcare databases. Findings: Vaccination coverage improved significantly from 68.4% at baseline in 2022 to 89.7% in 2025. Mobile vaccination clinics were the most effective, resulting in a 15.8% increase in coverage, followed by health education programs (12.4%). Logistic regression analysis showed that significant predictors of vaccine uptake were healthcare access (OR = 2.84), community participation (OR = 2.56) and parental education (OR = 2.31). Conclusion: Community-based interventions resulted in significant increases in vaccination coverage and reductions in immunization disparities among underserved pediatric populations. Innovative educational, technological and outreach-based strategies can improve vaccine access and foster sustainable outcomes for public health.
This study explores the enhancement of MMR vaccination rates in the deep south of Thailand through a culturally tailored intervention that incorporates storytelling and singing, aligning with local cultural and religious values. The “Anees has Measles” intervention, developed with input from community stakeholders including health workers, religious leaders, and parents, featured traditional melodies in its singing activities. The intervention comprised two main components: storytelling sessions and singing activities, both utilizing culturally resonant content and formats to effectively engage the community. Conducted from December 2019 to March 2020 across eight districts in five provinces, the study targeted children aged 18 months to 5 years in government child care centers. Results indicated a substantial increase in MMR vaccination coverage from 44.3% to 72.0% twelve months post-intervention, and further to 77.0% at 48 months post-intervention, representing a significant and sustained improvement (p < 0.001). This marked and continuous increase demonstrates the effectiveness of culturally adapted health education in areas with significant vaccine hesitancy. The findings highlight the importance of integrating culturally and religiously sensitive methods into public health strategies, significantly enhancing vaccine acceptance and coverage in diverse and conservative settings. This approach suggests a broader applicability for similar interventions in comparable contexts globally.

Vaccination is undoubtedly one of the most cost-effective child survival public health measure which are more affordable and accessible to community in preventing diseases. Government of India has undertaken several initiatives to strengthen maternal and child health services in the country and child immunisation being an important part of child healthcare system in India. The National Immunization Programme has taken many initiatives since its inception as Expanded Programme on Immunization in 1978. In recent years, there has been introduction of various newer vaccines. Introduction of pneumococcal vaccine in selected states in year 2017 and plan to scale up in the entire country is the newest change in National Immunization Schedule. This review aims to identify various articles related to pneumococcal infection and vaccine highlighting the burden, serotypic distribution, available vaccines, evidence regarding vaccine safety, efficacy, acceptability and cost effectiveness, in order to provide sufficient understanding on the demand and need of this vaccine in India. Important factors underpinned by this article are though there is a need of vaccination due to severe form of pneumococcal infections and antibiotic resistance due to which many developed countries have included PCV in their regular immunisation programmes, however studies regarding effectiveness of pneumococcal vaccines in developing countries like India, data regarding the burden of pneumococcal infections are not available. Also there are limited studies investigating the bacterial and viral etiology of Community Acquired Pneumonia and lack of data to show change in the serotype prevalence overtime. This review highlights the need of more research to provide substantial clinical and epidemiological evidence for the introduction of pneumococcal vaccine.
BACKGROUND: Sub-Saharan Africa has high under-5 mortality and low childhood immunisation rates. Vaccine-preventable diseases cause one-third of under-5 deaths. Text messaging reminders improve immunisation completion in urban but not rural settings in sub-Saharan Africa. Low adult literacy may account for this difference. The feasibility and impact of combined automated voice and text reminders on immunisation completion in rural sub-Saharan Africa is unknown. METHODS: We randomised parturient women at the Mother and Child Hospitals Ondo State, Nigeria, owning a mobile phone and planning for child immunisation at these study sites to receive automated call and text immunisation reminders or standard care. We assessed the completion of the third pentavalent vaccine (Penta-3) at 18 weeks of age, immunisation completion at 12 months and within 1 week of recommended dates. We assessed selected demographic characteristics associated with completing immunisations at 12 months using a generalised binomial linear model with 'log' link function. Feasibility was assessed as proportion of reminders received. RESULTS: Each group had 300 mother-baby dyads with similar demographic characteristics. At 18 weeks, 257 (86%) and 244 (81%) (risk ratio (RR) 1.05, 95% CI 0.98 to 1.13; p=0.15) in the intervention and control groups received Penta-3 vaccine. At 12 months, 220 (74%) and 196 (66%) (RR 1.12, 95% CI 1.01 to 1.25; p=0.04) in the intervention and control groups received the measles vaccine. Infants in the intervention group were more likely to receive Penta-3 (84% vs 78%, RR 1.09, 95% CI 1.01 to 1.17; p=0.04), measles (73% vs 65%, RR 1.13, 95% CI 1.02 to 1.26; p=0.02) and all scheduled immunisations collectively (57% vs 47%, RR 1.13, 95% CI 1.02 to 1.26; p=0.01) within 1 week of the recommended date. No demographic character predicted immunisation completion. In the intervention group, 92% and 86% reported receiving a verification reminder and at least one reminder during the study period, respectively. CONCLUSION: Paired automated call and text reminders significantly improved immunisation completion and timeliness. TRIAL REGISTRATION NUMBER: NCT02819895.

BACKGROUND: Pregnancy is a high-risk time for excessive weight gain. The rising prevalence of obesity in women, combined with excess weight gain during pregnancy, means that there are more women with obesity in the postnatal period. This can have adverse health consequences for women in later life and increases the health risks during subsequent pregnancies. OBJECTIVE: The primary aim was to produce evidence of whether or not a Phase III trial of a brief weight management intervention, in which postnatal women are encouraged by practice nurses as part of the national child immunisation programme to self-monitor their weight and use an online weight management programme, is feasible and acceptable. DESIGN: The research involved a cluster randomised controlled feasibility trial and two semistructured interview studies with intervention participants and practice nurses who delivered the intervention. Trial data were collected at baseline and 3 months later. The interview studies took place after trial follow-up. SETTING: The trial took place in Birmingham, UK. PARTICIPANTS: Twenty-eight postnatal women who were overweight/obese were recruited via Birmingham Women's Hospital or general practices. Nine intervention participants and seven nurses were interviewed. INTERVENTIONS: The intervention was delivered in the context of the national child immunisation programme. The intervention group were offered brief support that encouraged self-management of weight when they attended their practice to have their child immunised at 2, 3 and 4 months of age. The intervention involved the provision of motivation and support by nurses to encourage participants to make healthier lifestyle choices through self-monitoring of weight and signposting to an online weight management programme. The role of the nurse was to provide regular external accountability for weight loss. Women were asked to weigh themselves weekly and record this on a record card in their child's health record ('red book') or using the online programme. The behavioural goal was for women to lose 0.5-1 kg per week. The usual-care group received a healthy lifestyle leaflet. MAIN OUTCOME MEASURES: The primary outcome was the feasibility of a Phase III trial to test the effectiveness of the intervention, as assessed against three traffic-light stop-go criteria (recruitment, adherence to regular self-weighing and registration with an online weight management programme). RESULTS: The traffic-light criteria results were red for recruitment (28/80, 35% of target), amber for registration with the online weight loss programme (9/16, 56%) and green for adherence to weekly self-weighing (10/16, 63%). Nurses delivered the intervention with high fidelity. In the qualitative studies, participants indicated that the intervention was acceptable to them and they welcomed receiving support to lose weight at their child immunisation appointments. Although nurses raised some caveats to implementation, they felt that the intervention was easy to deliver and that it would motivate postnatal women to lose weight. LIMITATIONS: Fewer participants were recruited than planned. CONCLUSIONS: Although women and practice nurses responded well to the intervention and adherence to self-weighing was high, recruitment was challenging and there is scope to improve engagement with the intervention. FUTURE WORK: Future research should focus on investigating other methods of recruitment and, thereafter, testing the effectiveness of the intervention.

India's Universal Immunization Programme has been performing at a sub-optimal level over the past decade, with there being a wide disparity in terms of immunization coverage between states. This study investigates the covariates that affect immunization rates and inequality in India at the individual and district levels. We used data from the five rounds of the National Family Health Survey (NFHS), conducted from 1992-1993 to 2019-2021. We used multilevel binary logistic regression analysis to examine the association between demographic, socio-economic and healthcare factors and a child's full immunization status. Further, we used the Fairlie decomposition technique to understand the relative contribution of explanatory variables to a child's full immunization status between districts with different immunization coverage levels. We found that 76% of children received full immunization in 2019-2021. Children from less wealthy families, urban backgrounds, Muslims, and those with illiterate mothers were found to have lower chances of receiving full immunization. There is no evidence that gender and caste disparities have an impact on immunization coverage in India. We found that having a child's health card is the most significant contributor to reducing the disparities that exist regarding children's full immunization between mid- and low-performing districts. Our study suggests that healthcare-related variables are more crucial than demographic and socio-economic variables when determining ways in which to improve immunization coverage in Indian districts.

Childhood vaccination is crucial for safeguarding children against potentially life-threatening diseases. This study aims to investigate the significant factors influencing vaccination coverage among children aged 12–59 months in Bangladesh. The study utilizes cross-sectional data from the 2017–18 Bangladesh Demographic and Health Survey. A Kruskal–Wallis test is employed in bivariate analysis to identify significant predictors associated with childhood immunizations. A generalized Poisson regression model is applied to assess the impact of various risk factors on children’s incomplete vaccination status. Children born in the Sylhet division show lower chances of receiving immunizations. Additionally, children whose mothers are younger, have no education or only primary education, and are unemployed, are less likely to be fully vaccinated. Furthermore, children born into smaller families, first birth, those whose mothers had access to media, and those who received more than four antenatal visits during pregnancy are more likely to have received all recommended vaccines. Implementing targeted interventions to improve childhood vaccination coverage, particularly among vulnerable populations such as young and uneducated mothers with middle-income status, is crucial. Enhancing media access, promoting the utilization of antenatal care at health care facilities, and raising awareness about the benefits of vaccination can help ensure optimal vaccination coverage among children in Bangladesh.
