Vaccine awareness and hesitancy among Ukrainian refugee mothers in Bulgaria

Abstract Issue Migration carry out risk of disrupting the epidemiological well-being among refugees and host populations. Since the beginning of Ukraine crisis over 50 000 refugees remain in Bulgaria; 92% are women and children. There is suboptimal childhood immunization coverage among Ukrainian refugee community prior to arrival in Bulgaria. Description of the problem Childhood vaccination is mandatory in Bulgaria for TB, hepatitis B, diphtheria, tetanus, pertussis, poliomyelitis, rubella, measles, mumps, Haemophilus influenzae B and pneumococci. Refugees with uncertain immunization status are vaccinated according to the national immunization schedule and receive personal immunization card. As of March 2024, we conducted cross-sectional study to assess knowledge and attitudes of Ukrainian mothers through an interview. Results Of 105 mothers interviewed, 72.38% were with higher education. Arrived women were not familiar with Bulgarian health system and especially with vaccination. Absence of language barrier and presence of doctors among them facilitated our study.56.19% believe that migration has disrupted their children’s vaccinations. 56.19% consider that migration has disrupted their children’s vaccination. Aware of benefits of vaccines were 91,43%, they mainly trust doctors-84.76%, they pay attention to the positive discussion in the media-55.77%.Mothers realize the importance of herd immunity, considering that vaccinated children protect the others-68.57%.Leading reasons for mistrust of vaccines, mothers indicate - doubt in favor of vaccine-24.76%, medical contraindications for child-21.90% and doubts about quality of the vaccine-19.05%.They pay attention to positive discussion in the media-55.77% and have confidence in Bulgaria’s institutions. Lessons The Government of Bulgaria provided significant support and medical care for the prevention of vaccinepreventable diseases among Ukrainian children. Institutions and volunteers work for successful integration of refugees. Key messages • Need to know the immunization status of Ukrainian children admitted to Bulgaria. • Increasing trust in vaccines and the health system in general in Bulgaria requires additional explanatory campaigns among refugees.

Routine Immunization Status and Factors Associated with Immunization Coverage among Children Aged 12-23 Months in Tanzania.

Immunization has saved millions of lives globally from vaccine-preventable diseases. Childhood immunization is an effective public health strategy for decreasing morbidity and mortality among children in developing countries. Tanzania has one of the highest rates of coverage of routine child immunization among sub-Saharan African countries. However, obstacles to universal immunization still exist, particularly in rural areas of the country. Assessing routine immunization coverage is essential to inform vaccine policies and program implementation. This study aimed to assess routine immunization status and factors associated with its coverage among children aged 12-23 months. We conducted a cross-sectional, quantitative household survey in 31 regions with caretakers of children in Tanzania, where a total of 4,560 households were visited. Nationally, 85.5% of children aged 12-23 months had completed the full recommended course of vaccines. Overall, 14.5% of children aged 12-23 months did not complete routine immunization schedules in 2019. We found that factors associated with immunization coverage included having one to six family members, higher household wealth, the family's head engaging in subsistence farming, caretakers' age, children's age, educational level, children with clinic cards, and children receiving the diphtheria, pertussis, tetanus-3 vaccine. The country is about to reach the vaccination coverage target set by the WHO and the United Nations Children Fund. Improving existing vaccination coverage and optimizing the use of recommended interventions are required. We strongly advise using the periodic micro-planning tool and satellite image technology, particularly in areas where immunization coverage is less than 80%.

Faktor-Faktor yang Berhubungan dengan Kejadian TB Paru pada Anak di Poliklinik RSUD Embung Fatimah

Pulmonary TB in children is an infection caused by the germ Mycobacterium Tuberculosis. Pulmonary TB is transmitted from human to other human through the air when a BTA positive pulmonary TB sufferer talks, sneezes or coughs and indirectly the sufferer emits phlegm splashes in the air and there are ±3000 phlegm splashes containing germs. This research was conducted to determine the factors associated with the incidence of pulmonary TB in children at the Embung Fatimah Regional Hospital Polyclinic. The research method is descriptive with a cross sectional design. The sample consisted of 34 pediatric TB patients at the Embung Fatimah Regional Hospital Polyclinic using a sampling technique, namely total sampling. Data were processed using the chi square test. The results of this study show that there is no significant relationship between BCG immunization status and the incidence of pulmonary TB in children (P value of 0.450 > 0.05), there is a significant relationship between contact with TB sufferers and the incidence of TB in children (P value of 0.021 > 0.05), and there is a significant relationship between family smoking status and TB sufferers and the incidence of TB in children (P value of 0.014 > 0.05). It is hoped that the role of nurses can overcome the problem of childhood TB through health promotion and increasing immunization coverage for children in the community.

Inequality in Childhood Immunization Coverage: A Scoping Review of Data Sources, Analyses, and Reporting Methods.

Immunization through vaccines among children has contributed to improved childhood survival and health outcomes globally. However, vaccine coverage among children is unevenly distributed across settings and populations. The measurement of inequalities is essential for understanding gaps in vaccine coverage affecting certain sub-populations and monitoring progress towards achieving equity. Our study aimed to characterize the methods of reporting inequalities in childhood vaccine coverage, inclusive of the settings, data source types, analytical methods, and reporting modalities used to quantify and communicate inequality. We conducted a scoping review of publications in academic journals which included analyses of inequalities in vaccination among children. Literature searches were conducted in PubMed and Web of Science and included relevant articles published between 8 December 2013 and 7 December 2023. Overall, 242 publications were identified, including 204 assessing inequalities in a single country and 38 assessing inequalities across more than one country. We observed that analyses on inequalities in childhood vaccine coverage rely heavily on Demographic Health Survey (DHS) or Multiple Indicator Cluster Surveys (MICS) data (39.3%), and papers leveraging these data had increased in the last decade. Additionally, about half of the single-country studies were conducted in low- and middle-income countries. We found that few studies analyzed and reported inequalities using summary measures of health inequality and largely used the odds ratio resulting from logistic regression models for analyses. The most analyzed dimensions of inequality were economic status and maternal education, and the most common vaccine outcome indicator was full vaccination with the recommended vaccine schedule. However, the definition and construction of both dimensions of inequality and vaccine coverage measures varied across studies, and a variety of approaches were used to study inequalities in vaccine coverage across contexts. Overall, harmonizing methods for selecting and categorizing dimensions of inequalities as well as methods for analyzing and reporting inequalities can improve our ability to assess the magnitude and patterns of inequality in vaccine coverage and compare those inequalities across settings and time.

Assessing the resilience of child immunisation programmes using geospatial modelling and interrupted time series analysis in Ethiopia and Kenya amidst the COVID-19 pandemic: tracking coverage and identifying key challenges

IntroductionThe COVID-19 pandemic disrupted healthcare provision and access in sub-Saharan Africa. Lockdowns and travel restrictions, coupled with fear of contracting the virus, disrupted services, especially for women’s and children’s health,...

Of Money and Men: A Scoping Review to Map Gender Barriers to Immunization Coverage in Low- and Middle-Income Countries.

Among the multiple factors impeding equitable childhood immunization coverage in low- and middle-income countries (LMICs), gender barriers stand out as perhaps the most universal. Despite increasing recognition of the importance of gender considerations in immunization programming, there has not yet been a systematic assessment of the evidence on gender barriers to immunization. We conducted a scoping review to fill that gap, identifying 92 articles that described gender barriers to immunization. Studies documented a range of gender influencers across 43 countries in Africa and South Asia. The barrier to immunization coverage most frequently cited in the literature is women's lack of autonomous decision-making. Access to immunization is significantly impacted by women's time poverty; direct costs are also a barrier, particularly when female caregivers rely on family members to cover costs. Challenges with clinic readiness compound female caregiver's time constraints. Some of the most important gender barriers lie outside of the usual purview of immunization programming but other barriers can be addressed with adaptations to vaccination programming. We can only know how important these barriers are with more research that measures the impact of programming on gender barriers to immunization coverage.

Specialist nurse's health promotion work with the national childhood immunization programme: A qualitative study.

Childhood immunizations have proven to be one of the most beneficial interventions to promote public health and prevent childhood deaths due to disease. However, global coverage of childhood immunization has decreased throughout the world due to guardians' growing hesitancy towards immunizations. This study aims to describe how specialist nurses promote legal guardians to adhere to national childhood immunization programmes. This study had a qualitative design. Semistructured interviews with 11 specialist nurses, who were paediatric primary care nurses or nurse practitioners, were conducted. Data were analysed using qualitative content analysis. The findings, with four main categories including four subcategories, showed nurses using both local guidelines and national guidelines to promote guardians to adhere to the childhood immunization programme. The main intervention the nurses did to promote childhood immunization coverage was giving legal guardians general information about the programme. With hesitant guardians, adopting a person-centred approach towards the legal guardian improved adherence. Further research should focus on how specialist nurses can respond to guardians who decline immunization for their children, as this study identified difficulties in this area. Furthermore, research on guardians' perspectives towards childhood immunization may also help generate further effective guidance on how to promote immunization coverage among children.

The synergistic impact of Universal Health Coverage and Global Health Security on health service delivery during the Coronavirus Disease-19 pandemic: A difference-in-difference study of childhood immunization coverage from 192 countries.

Universal Health Coverage (UHC) and Global Health Security (GHS) are two high-priority global health agendas that seek to foster health system resilience against health emergencies. Many countries have had to prioritize one agenda over the other due to scarce resources and political pressures. To aid policymakers' decision-making, this study investigated the individual and synergistic effects of countries' UHC and GHS capacities in safeguarding essential health service delivery during the COVID-19 pandemic. We used a quasi-experimental difference-in-difference methodology to quantify the relationship between 192 countries' progress towards UHC and GHS and those countries' abilities to provide 12 essential childhood immunization services between 2015 and 2021. We used the 2019 UHC Service Coverage Index (SCI) to divide countries into a "high UHC group" (UHC SCI≥75) and the rest (UHC SCI 75), and similarly used the 2019 GHS Index (GHSI) to divide countries into a "high GHS group" (GHSI≥65) and the rest (GHSI<65). All analyses were adjusted for potential confounders. Countries with high UHC scores prevented a 1.14% (95% CI: 0.39%, 1.90%) reduction in immunization coverage across 2020 and 2021 whereas countries with high GHSI scores prevented a 1.10% (95% CI: 0.57%, 1.63%) reduction in immunization coverage over the same time period. The stratified DiD models showed that across both years, high UHC capacity needed to be augmented with high GHS capacity to prevent a decline in immunization coverage while high GHS alone was able to safeguard immunization coverage. This study found that greater progress towards both UHC and GHS capacities safeguarded essential health service delivery during the pandemic but only progress towards GHS capacity was both a necessary and likely sufficient element for yielding this protective effect. Our results call for strategic investments into both health agendas and future research into possible synergistic effects of the two health agendas.

Decentralization and immunization program in a single-party state: the case of the Lao People’s Democratic Republic

BackgroundThe Lao People’s Democratic Republic (Lao PDR), a lower-middle-income country, lags behind other Southeast Asian countries in immunization coverage for children under two years of age. The organization of health services is a key determinant of the functionality of immunization programs. However, this aspect, and in particular its decentralization component of the healthcare system, has never been studied.MethodsA case study in the Lao National Immunization Program was performed using a neo-institutional theory-based conceptual framework, highlighting the structure (rules, laws, resources, etc.) and interpretative schemes (dominant beliefs and ideas) that underlie the state of decentralization of the healthcare system that support the conduct of the immunization program. Twenty-two semi-structured interviews were conducted with representative actors from various government levels, external donors, and civil society, in four provinces. Data were complemented with information retrieved from relevant documents.ResultsThe Lao healthcare system has a deconcentrated form of decentralization. It has a largely centralized structure, albeit with certain measures promoting the decentralization of its immunization programs. The structure underlying the state of centralization of immunization services provided is coherent with a shared dominant interpretive scheme. However, the rapid economic, technical, and educational changes affecting the country suggest that the coherence between structure and interpretative schemes is bound to change.ConclusionUnprecedented opportunities to access quality higher education and the use of social networks are factors in Lao PDR that could affect the distribution of responsibilities of the different levels of government for public health programs such as the National Immunization Program.

Demographic determinants of poor childhood immunization coverage among women in Bayelsa state

The study examined at the extent demographic factors influence childhood immunization coverage in Bayelsa State. The design was cross-sectional. The total female population of Bayelsa State is estimated to be 1,116, 200.9. National Population Commission and National Bureau of Statistics (2016); National Bureau of Statistics (2018) According to the World Health Organizatio, women of reproductive age account for 22% of the total population of 501, 502 people. The study population consists solely of women in Bayelsa State who have child(ren) between the ages of 0 and 5 years. A multi-stage procedure was used to select 20 women with at least one child under the age of five from each selected community, yielding a sample size of 1100. The instrument's internal consistency was assessed using Cronbach's Alpha statistics, yielding a reliability of 0.77. At the 0.05 level of significance, simple regression statistics was used to analyze the hypotheses. The findings revealed that mothers’ age and education influence childhood immunization coverage, as the educated and older mothers have higher probability of getting their children immunized completely. Maternal education was recommended in the State, also that the National Orientation Agency should ensure mass media exposure and community education awareness and campaigns on immunization.

Perbandingan Angka Cakupan Imunisasi Dasar Anak Sebelum, Selama dan Setelah Pandemi Covid-19

This research aims to provide a clear picture of the impact of the Covid-19 pandemic on children's basic immunization coverage at the Parongpong Community Health Center, West Bandung Regency from 2019-2023. The research uses a quantitative descriptive approach with sampling techniques using methodstotal sampling. The data used is secondary data from monthly reports of routine immunization results every month. The research results show that the basic immunization coverage rate for children in the Parongpong Community Health Center working area before the 2019 Covid-19 pandemic had good coverage with the highest coverage in December amounting to 1237 (115%). In 2020, during the pandemic, basic immunization coverage for children experienced a significant decline with the highest coverage in January being only 514 children (48%) and in 2021 increasing with the highest coverage being 953 children (88%). In 2022 there will be an insignificant decline. After the Covid-19 Pandemic in 2023, the figure for basic immunization coverage among children showed an increase of 88% or around 953 children were vaccinated. Conclusion, there is a comparison of basic immunization coverage rates for children before, during and after the Covid-19 pandemic. This shows the need for special attention in efforts to restore and increase children's basic immunization coverage after the pandemic. Keywords: Immunization Coverage, Covid-19, Basic Immunization

IJCM_225A: Assessment of factors influencing measles vaccine uptake in a metropolitan city: A cross-sectional study

Background: Globally, measles deaths were estimated to be over 1,28,000 in the year 2021, despite the easy availability of safe and effective vaccines to prevent the infection. Routine childhood immunization coverage rates dropped during the COVID-19 pandemic and India has been one of the worst affected countries. The most recent measles outbreak was reported last year in Mumbai, Maharashtra. Objectives: 1. To estimate the level of uptake of measles vaccine in children aged 12 months to 5 years 2. To determine the factors associated with the uptake of measles vaccine. Methodology: This cross-sectional study was conducted over 2 months in a municipal ward of Mumbai during Oct-Nov 2023 in mothers with children aged 12 to 60 months, living in the area for at least past 6 months. Five out of fifteen clusters of Municipal Health Post areas were selected randomly &amp; from each, 82 eligible households were chosen randomly for door-to-door interviews with the participants. Results: Among the sample of 428 children, measles vaccine coverage was 96.7%, but only 263 (61.45%) children were vaccinated in timely manner. The facilitator for mothers in vaccine uptake was receiving information from healthcare workers during and after pregnancy (77.57%). The barriers were lack of information about vaccination schedule (18.69%), and child being unwell during vaccination (10.74%). Conclusion: Huge efforts have been taken by the Public Health Department for achieving this level of vaccine coverage, however, measles elimination is still a challenge due to delayed vaccination.

Coverage, mapping and barriers to complete vaccination for age among children under 5 years in 2021: case of Adjara-Hounvè and Ahouicodji villages in southern Benin

Vaccination is a protective measure against infectious diseases and remains one of the best investments in public health. Some African countries are still struggling to reach the required child immunization coverage. Several factors are responsible for limiting immunization coverage. Most of the factors considered to limit immunization coverage are related to the health system. In addition, inaccessibility to care, especially during the critical period of the Covid-19 pandemic, greatly reduced vaccination coverage rates. In Benin, several vaccines are included in the Expanded Programme on Immunization or are administered as part of routine immunization. However, cases of non-compliance with the vaccine and persistent flaccid paralysis are still recorded in the commune of Ouidah in southern Benin. The aim of this study was to investigate the coverage and factors associated with full immunization for age in children aged 0-5 years. A cross-sectional survey was conducted from August to October 2021 in two villages (Adjara-Hounvè and Ahouicodji) in southern Benin. All the households were included. The survey regarded children under 5 for whom a vaccination record was presented. A couple child/mother was recruited after informed consent of the mother and her child. An univariate analysis followed by a multivariate analysis was performed by using a logistic regression model to identify the variables that influence vaccine completeness. Spatial description of vaccine completeness was performed using the kriging method using ArcGIS 10.8 mapping software. Results. Of the 414 mothers surveyed, 57.49% had an immunization card, from which information was collected. Of the 238 children recruited, 141 were in Adjara-Hounvè and 97 in Ahouicodji. Of the 238 children with an immunization card, 20.6% were fully immunized for their age. All children received Baccille Calmette Guérin vaccine at birth. Since poliomyelitis, pentavalent, pneumococcal conjugate, and rotavirus are three-dose vaccines, the percentage of children who received these vaccines decreased as the number of doses increased: 96.6%, 88.2%, 78.1% and 72.3% for the four doses of polio respectively. According to 53.4% of the respondents the reception at the vaccination site was poor, and according to 70.3% of them waiting time for vaccination sessions was long. Several reasons justified the absence of complete vaccination for the age of the children: vaccination site too far from the place of residence (59.54%), lack of financial means (29.78%) and the mother's ignorance (12.76%). Education level "primary" vs "none" (ORa = 3.32; CI95% 1.07-10.25), occupation "health staff" vs "housewife" (ORa = 21.18; CI95% 3.07-145.94), mothers' knowledge of Expanded Programme on Immunization diseases (ORa = 2, 20; CI95% 1.03-4.68) and children's age 0-2 months vs ≥ 16 months (ORa = 8.53; CI95% 2.52-28.85) and 9-15 months vs ≥ 16 months (ORa = 2.99; CI95% 1.24-7.23) increased complete immunization status for age. The homogeneity of behaviour related to age-complete immunization coverage in children under 5 years was evident at mapping. Age-complete immunization coverage in children under 5 years of age is very low, with a spatial homogeneity in community immunization uptake behaviour. Age-complete immunization coverage is an innovative indicator that can contribute to achieving age-specific immunization targets.

Acute malnutrition relapse and associated factors among 6-59 months old children treated in the community-based management of acute malnutrition in Dessie, Kombolcha, and Haik towns, Northeast Ethiopia.

Undernutrition is a major health concern in many developing countries, and is one of the main health problems affecting children in Ethiopia. Although many children experience multiple relapses following the management of severe acute malnutrition, it is scarcely studied in Ethiopia. A community-based cross-sectional study was conducted in Dessie, Kombolcha, and Haik towns among 6-59-month-old children enrolled and discharged from community-based acute malnutrition management (CMAM). The total sample size was 318 children, and data were collected from April 15, 2021, to May 14, 2021. The data were entered into EPI data version 4.4.1 before being exported and analyzed with SPSS version 25 software. A multivariate logistic regression analysis was performed, and a 95% confidence interval and p-value <0.05 were used to identify significantly associated variables. Additionally, the weight-for-height z-score (WHZ) was generated using the WHO Anthro 3.2.2 software. The overall acute malnutrition relapse after discharge from CMAM was 35.2% (6.6% relapsed to severe acute malnutrition and 28.6% relapsed to moderate acute malnutrition). The following variables were significantly associated with the relapse of acute malnutrition: child age (AOR: 3.08, 95% CI; 1.76, 5.39), diarrhea after discharge (AOR: 2.93, 95%CI; 1.51, 5.69), have not immunized (AOR: 3.05, 95% CI; 1.14, 8.23), MUAC at discharge (AOR: 3.16, 95% CI; 1.56, 6.40), and poorest and poor wealth index (AOR: 3.65, 95% CI; 1.45, 9.18) and (AOR: 2.73, 95% CI; 1.13, 6.59), respectively. Over one-third of children treated with the CMAM program reverted to SAM or MAM. The age of the child, diarrhea after discharge, lack of immunization, MUAC at discharge (<13 cm), and poor and poorest wealth index were significantly associated with acute malnutrition relapse. Therefore, adequate health education and counseling services are essential for mothers to improve child immunization coverage and maintain adequate hygiene to prevent diarrhea. In addition, further experimental research is needed to investigate the effect of MUAC at discharge on the risk of acute malnutrition relapse.

Child Immunization Coverage in Urban Settings of Twelve Provinces Plus Kabul, Afghanistan, 2019.

Background: Low immunization and discrepancies in data sources have been a consistent challenge in Afghanistan. The objective of this was to estimate the coverage of immunization status among children of 12-23 months in urban settings of 12 provinces plus Kabul, Afghanistan in 2019. Methods: A cross-sectional survey was conducted in the capital of 12 cities of polio high-risk provinces plus Kabul during October-December 2019. A two-stage cluster sampling was used to approach 30 clusters and interview seven households. The coverage for 13 vaccines against 10 childhood diseases prioritized by the Afghanistan Immunization program was assessed through observation of vaccine cards or by history from caregivers of children. Epi Info v.7.2.5 was used for data management and analysis. Results: Totally, 3382 caregivers of children aged 12-23 months, of whom 50.8% were boys, were interviewed. The literacy of mothers was 35%, and 86.4% were housewives with no formal employment. The average age of children was 17.07 ± 4.05 months. In total, 1261 (37.29%) children were fully vaccinated, 833 (54.2%) were partially vaccinated, and 288 (8.52%) did not receive any dose of routine vaccine. Of total, 71.82% had vaccination cards, 17.24% had lost them, and 11% had no cards. Generally, coverage of immunization by cards and history was 91.70% for BCG, 52% for Penta, 78% for OPV-4, 63% for PCV2, 61% for Rota2, 68.50% for measles 1, and 58% for IPV. Nangarhar and Kunar provinces have the highest and lowest immunization coverage, respectively. Lack of awareness and time was the main factor cited by partially vaccinated individuals, while misconceptions about vaccines were reported among the unvaccinated. Conclusion: Child immunization levels, varying across cities, were suboptimal in the study population. Realistic goal-setting and awareness campaigns are necessary to address the low immunization coverage and fight against barriers in Afghanistan.

Influence of women empowerment on childhood (12–23 months) immunization coverage: Recent evidence from 17 sub-Saharan African countries

BackgroundThere is a global consensus that child immunization plays an important role in promoting the health and well-being of children. Despite the quintessential role of immunization, not all children receive full immunization coverage. We examined the association between women empowerment and childhood immunization coverage in sub-Saharan Africa (SSA).MethodsThe most recent Demographic and Health Survey data of 17 SSA countries were used for the analysis, with a sample of 19,223. The outcome and exposure variables were full immunization coverage and women empowerment, respectively. Full immunization was computed from percentage of children between the ages of 12 and 23 months who had received the following vaccines at any point in time: one dose of Bacille Calmette–Guérin, three doses of the vaccine protecting against diphtheria, pertussis, and tetanus or the tetravalent/pentavalent vaccine, three doses of the polio vaccine, and one dose of the measles vaccine (either as a standalone measles vaccine or as part of a combination with other immunogens). Women’s empowerment was an index of labour participation, acceptance towards spousal violence, decision-making capacity and general knowledge level. Descriptive analysis and multilevel logistic regression were performed. Results were reported in adjusted odds ratio with a corresponding 95% confidence interval.ResultsThe study found that 56.6% of children were fully immunized. Children of employed mothers were 1.16 times more likely to be fully immunized. Children of mothers with higher acceptance toward violence were less likely to be fully immunized [aOR = 0.90, CI 0.81, 0.99]. The odds of full immunization were higher among children born to mothers with high [aOR = 1.11, CI 1.01, 1.22] decision-making capacity. Higher odds of full immunization were found among children born to mothers with medium [aOR = 1.24, CI 1.13, 1.36] to high [aOR = 1.44, CI 1.27, 1.63] general knowledge level.ConclusionsWe conclude that empowering women through livelihood empowerment interventions can increase their decision-making capacity and foster their resolve to ensure the full immunization of their children. This can be achieved by consciously investing in initiatives such as vocational training programs, job placement services, or support for entrepreneurship initiatives to encourage and support women's workforce participation.

Cost-efficient child vaccination project results from hard-to-reach rural communities in Kenya

Abstract Child immunization is a cost-effective public health measure for reducing child morbidity and mortality. Child immunization coverage in Kenya has improved in recent years, with coverage rates for most vaccines exceeding 80%. However, there are still pockets of low coverage, particularly in remote or hard-to-reach areas. We implemented a community-based project to improve access and equity in child immunization services in three Kenyan counties (Nairobi, Wajir and Mandera). We trained health workers, promoted community acceptance, and provided logistical support to Ministry of Health (MoH) for child immunization services through community outreach centers. During the project period (January 2020 to February 2023), our project facilitated full immunization coverage for 93,879 children and we reached 200,554 community members whom we communicated relevant messages for recommended practice about health, nutrition and child vaccination. Our project achieved a 26 percentage-point increase (increased from 62% at baseline in 2020 to 88% at endline in 2022) in age-appropriate child vaccinations by end of the project. We also conducted a cost-efficiency analysis by taking the actual costs incurred and project achievements into account. The key results from the cost-efficiency analysis revealed approximate cost for a fully immunized child as 21 US dollar, while per capita cost for communicating health messages to community members and health care worker training was 10 US dollar. UNICEF estimated approximately 32 US$ as vaccine delivery cost (=total cost - cost of vaccine and supply) per fully vaccinated child with standard schedule for children &amp;lt; 24 months which is higher than the cost for ensuring a fully immunized child in our project. These data clearly indicate the efficiency and success of community-based approach for strengthening MoH child immunization services in Kenyan rural and hard-to-reach communities. Key messages • Strong collaboration with Ministry of Health and community participation are critical key aspects for implementing child vaccination program successfully and cost-efficiently in rural communities. • Facilitating Ministry of Health for health system strengthening focus yields sustainable impact as footprint after end of a short-term of a community based project in developing country settings.

High vaccine confidence and strong approval of the mandatory immunization schedule among Bulgarian general practitioners in 2022

ABSTRACT In a context of recently decreasing childhood immunization coverage and low uptake of COVID-19 vaccines in Bulgaria, this study measures vaccine hesitancy among general practitioners (GPs) in the country, as they are central to forming patients’ attitudes. In 2022, a face-to-face survey was conducted through a simple random sample from an exhaustive national database of Bulgarian GPs. This study measured attitudes on vaccine importance, safety, and effectiveness, and attitudes toward the Bulgarian immunization schedule. Information was collected on demographic and GP practice characteristics and possible predictors of vaccine confidence in order to test for associations with attitudes toward immunization. GP attitudes toward vaccines and the immunization schedule in Bulgaria were generally positive. Among 358 respondents, 351 (98%,95%CI96–99%) strongly agreed/agreed that vaccines are important, 352 (98%,95%CI96–99%) that vaccines are effective, and 341 (95%,95%CI93–97%) that vaccines are safe. 347 respondents (97%,95%CI95–98%) affirmed that “it’s good that vaccines from the children’s immunization schedule are mandatory”, and 331 (92%,95%CI89–95%) agreed with the statement “Bulgaria’s childhood immunization has my approval”. Trust in information from official institutions was among the strongest predictors of vaccine confidence. Respondents’ vaccine confidence levels are within the ranges reported by GPs in other European countries and above those reported within the general Bulgarian population. GPs’ vaccine confidence is highly associated with trust in official institutions. It is important to maintain trust in official institutions and to support GPs in communicating vaccine knowledge with patients so that vaccine hesitancy in the general population is countered.

Immunization coverage, knowledge, satisfaction, and associated factors of non-National Immunization Program vaccines among migrant and left-behind families in China: evidence from Zhejiang and Henan provinces

BackgroundMigrant and left-behind families are vulnerable in health services utilization, but little is known about their disparities in immunization of non-National Immunization Program (NIP) vaccines. This study aims to evaluate the immunization coverage, knowledge, satisfaction, and associated factors of non-NIP vaccines among local and migrant families in the urban areas and non-left-behind and left-behind families in the rural areas of China.MethodsA cross-sectional survey was conducted in urban areas of Zhejiang and rural areas of Henan in China. A total of 1648 caregivers of children aged 1–6 years were interviewed face-to-face by a pre-designed online questionnaire, and their families were grouped into four types: local urban, migrant, non-left-behind, and left-behind. Non-NIP vaccines included Hemophilus influenza b (Hib) vaccine, varicella vaccine, rotavirus vaccine, enterovirus 71 vaccine (EV71) and 13-valent pneumonia vaccine (PCV13). Log-binomial regression models were used to calculate prevalence ratios (PRs) and 95% confidence intervals (CIs) for the difference on immunization coverage of children, and knowledge and satisfaction of caregivers among families. The network models were conducted to explore the interplay of immunization coverage, knowledge, and satisfaction. Logistic regression models with odds ratios (ORs) and 95% CIs were used to estimate the associated factors of non-NIP vaccination.ResultsThe immunization coverage of all non-NIP vaccines and knowledge of all items of local urban families was the highest, followed by migrant, non-left-behind and left-behind families. Compared with local urban children, the PRs (95% CIs) for getting all vaccinated were 0.65 (0.52–0.81), 0.29 (0.22–0.37) and 0.14 (0.09–0.21) among migrant children, non-left-behind children and left-behind children, respectively. The coverage-knowledge-satisfaction network model showed the core node was the satisfaction of vaccination schedule. Non-NIP vaccination was associated with characteristics of both children and caregivers, including age of children (> 2 years-OR: 1.69, 95% CI: 1.07–2.68 for local urban children; 2.67, 1.39–5.13 for migrant children; 3.09, 1.23–7.76 for non-left-behind children); and below caregivers’ characteristics: family role (parents: 0.37, 0.14–0.99 for non-left-behind children), age (≤ 35 years: 7.27, 1.39–37.94 for non-left-behind children), sex (female: 0.49, 0.30–0.81 for local urban children; 0.31, 0.15–0.62 for non-left-behind children), physical health (more than average: 1.58, 1.07–2.35 for local urban children) and non-NIP vaccines knowledge (good: 0.45, 0.30–0.68 for local urban children; 7.54, 2.64–21.50 for left-behind children).ConclusionsThere were immunization disparities in non-NIP vaccines among migrant and left-behind families compared with their local counterparts. Non-NIP vaccination promotion strategies, including education on caregivers, and optimization of the immunization information system, should be delivered particularly among left-behind and migrant families.Graphical
