Centering community-based maternal and child nutrition services in Bangladesh’s rural primary healthcare: what has potential to scale

IntroductionThe extensive network of community health workers in rural Bangladesh has the potential to deliver maternal and child nutrition services, while promoting linkages with healthcare facilities. A strategy for strengthening community-based nutrition services was developed and tested.MethodsThe three-phased strategy included review of existing community-based systems, co-designing service package with multi-sector government representatives, and testing implementation feasibility. Integrated health and nutrition service delivery, supportive supervision, and increased accountability of local government were core components of the service package being implemented in selected geographies since March 2023. The assessment followed a mixed-method design with household survey of 1,166 pregnant women, mothers of children under-6 months and 6–23 months, and observations of 965 service delivery points along with qualitative study.ResultsA higher proportion of children received growth monitoring and promotion (GMP) services through expanded program on immunization (EPI) sessions, with better compliance to service delivery protocol in intervention areas compared with controls. Maternal nutrition services of gestational weight gain monitoring and distribution of supplements were better available in intervention areas. However, minimum dietary diversity among pregnant women (69% intervention, 72% control), early initiation of breastfeeding (55% intervention, 51% control), and complementary feeding practices were comparable in intervention and control areas. Nutrition services were successfully integrated in supervision which earlier covered EPI and family planning. The local government contributed to strengthening nutrition services but at a small scale.DiscussionThere is potential to scale-up GMP services through EPI and merging antenatal clinics with GMP and EPI such that all maternal and childcare services are available at the same place and same time. A coordinated investment and oversight from multiple national government departments is needed. At district and sub-district levels, scale-up requires joint annual planning of nutrition and EPI services, strengthened management of nutrition services, bridging health worker vacancies, introducing volunteers in sites with high EPI case load, capacity building, and supportive supervision. Replacement of multiple health and nutrition records with a single mother and child health and nutrition card is also feasible. However, behavior change interventions through home visits and courtyard meetings need more testing before recommending scale-up.

Assessment of Knowledge, Attitude and Practice Towards Childhood Vaccination among Pregnant Mothers Attending ANC Follow-Up at SPHMMC

Introduction: A vaccine-preventable disease is an infectious disease for which an effective preventive vaccine exists. The Expanded Program on Immunization (EPI) was established globally in 1974 to protect child health by routine immunization against diphtheria, tetanus, pertussis, poliomyelitis, measles and tuberculosis. Apart from the scarce resource of vaccines, awareness towards vaccines, the attitude towards it and practicability are major issues. Since Antenatal period is a birth preparedness period awareness towards VPD is essential.

A discrete choice experiment on Chinese parents' preferences of vaccine schedules against six childhood infectious diseases.

China's Expanded Program on Immunization (EPI) provides vaccinations against 12 vaccine preventable diseases (VPDs) at no cost to families. For some VPDs, parents may opt to substitute equivalent non-program vaccines, including combination vaccines, for EPI vaccines; substitute vaccines must be paid for by the family. Although parents have several choices for vaccinating their children, their preferences for vaccines and immunization schedules have not been systematically evaluated. We used a discrete choice experiment to evaluate four attributes of vaccines for routine immunization: number of injections, risk of mild side-effects, out-of-pocket cost, and location of manufacturer (domestic or imported). In a questionnaire-based survey conducted in vaccination clinics, guardians were asked to select their preferred vaccination schedule from five options in ten choice sets with the four attributes. We used a mixed logit model to determine parental preferences for vaccination schedules, relative importance of attributes, and predict the likelihood of successful vaccination under different scenarios. A total of 581 parents from seven provinces and cities in China participated in the survey, and 488 respondents had internally consistent responses and were included in the analysis. The number of injections in the schedule was the most important attribute for predicting uptake, followed by risk of mild side-effects. Preferences varied by region and parental role. Predicted uptake in the preferred vaccination scenario relative to base-case schedule uptake was a 99.55% increase. Number of injections and risk of mild side-effects were the two most important attributes of the routine immunization schedule. Results from this study can help optimize the immunization schedule in China to improve coverage of childhood vaccines.

Assessing the Effectiveness of Financial Management Technical Assistance to Immunization Programs:A Case Study on the Use of Mobile Money Payment Mechanisms in the Expanded Program on Immunization (EPI) Liberia

Molecular characterization and antimicrobial susceptibility for 62 isolates of Bordetella pertussis from children.

Pertussis is a highly contagious respiratory disease caused by Bordetella pertussis (BP). Despite global control of pertussis cases through the Expanded Programme on Immunization (EPI), there has been a significant increase in the incidence of pertussis in recent years, characterized by a "resurgence" in developed countries with high immunization rates as well as a comparable reemergence in certain areas of China. We aim to explore the genotypes and antimicrobial susceptibility of circulating BP from children in Hebei. Children diagnosed with BP infection from 2019 to 2020 in Hebei, China were enrolled. We performed antimicrobial susceptibility testing (AST), whole-genome sequencing (WGS) analysis, single nucleotide polymorphism (SNP) detection, mltilocus sequence typing (MLST), multilocus antigen sequence typing (MAST), multilevel genome typing (MGT). A total of 313 international BP genomes were selected for comparison to examine the genomic diversity and evolutionary traits of Chinese strains within a global framework. Sixty-two individuals were identified with BP infection via culture, yielding a positive rate of 15.62% (62/397) for BP. Two phylogenetic groups were identified, each carrying a dominating genotype. The two vaccine strains, CS and Tohama I, exhibited a distant relationship to these two groups. This study identified 56 erythromycin-resistant isolates, 55 azithromycin-resistant isolates, 58 sulfamethoxazole-sensitive isolates, and 53 cefotaxime-sensitive isolates. All BP isolates were sensitive to levofloxacin, amoxicillin, ceftriaxone, and meropenem. Meanwhile, all erythromycin-resistant strains, which belonged to lineage I and MGT2 sequence type 7 (ST7), shared the ptxP1 gene and contained the 23S rRNA A2047G mutation. The major MAST was prn1/ptxP1/ptxA1/fim3-1/fim2-1 (75.81%). All 62 BP strains were divided into 1, 2, 3, 14, and 52 types at the MGT1, MGT2, MGT3, MGT4, and MGT5 levels, respectively. This work showed that there may be a link between antimicrobial resistance and alterations in specific molecular types, and the isolates showed a clear change when compared with the vaccine strain and that selection pressure from both antibiotics and immunization may be responsible for driving Chinese BP evolution, and necessitate a reevaluation of the immunization strategy and the development of novel vaccines in China to halt the resurgence and medication resistance of pertussis.

Mothers’ Knowledge, Attitude and Practice about Expanded Program on Immunization (EPI) Vaccination: A Sociological Study in District Dera Ghazi Khan

Vaccination is aspect of public health that is considered the most cost-effective in reducing the prevalence of life-threatening disease. Therefore, it is important to have a sufficient amount of knowledge, a positive attitude, and correct practice regarding vaccinations. So present study has been designed to actually find out the mothers’ Knowledge, attitude, and practice about the expanded program on Immunization (EPI) Vaccination in district D.G Khan. The main objectives of the study are; (i) to identify the socioeconomic characteristics of the respondent; (ii) to assess the knowledge of mothers regarding childhood vaccination; (iii) to assess the perception of respondents about the availability and difficulty of EPI vaccination in the local study area; (iv) to suggest some recommendation’ to improve the accessibility of general care and encourage peoples for immunization activities and to enhance the parental level of knowledge for a positive attitude, and correct practice regarding vaccinations. In this regard, a survey was conducted, and data was collected through a multistage sampling technique from 200 mothers in tehsil Taunsa. The results showed that the majority 70.0% of the mothers possessed education up to matric; (SSC); 76.0% of respondents were of age group 20-30 years; 55.0% had 1 to 3 children; 58.0% of respondents were housewives; 93.5% mothers had knowledge about EPI vaccination; 89.0% said that difficulty of EPI vaccination is caused by lack of public awareness; 91.5% mentioned that availability of EPI vaccinations is important for parents;92.5% mentioned that availability of EPI vaccinations necessary for children;92.0% said that availability of vaccinations was caused to protect the children healthy life; 90.5% accessibility of general care encourage people for immunization. Results also showed a significant relationship between the availability of vaccination vs life protection of children; the Presence of doctors and paramedical staff vs adoption of vaccination and accessibility of general care vs immunization activities among people. Research suggested that the government should start an awareness program for the mothers regarding complete knowledge of EPI as well as ensure the availability of vaccination in hospitals i.e. DHQs, THQs, RHCs & BHUs for better child-mother health.

Securing the Future: Strategies for Global Polio Vaccine Security Amid Eradication Efforts.

Background/Objectives: As we commemorate 50 years of the Expanded Programme on Immunization (EPI), the global mission to eradicate polio stands at a critical juncture. While remarkable progress has been made over the past decades, ensuring a steady supply of polio vaccines remains a significant challenge that could undermine these achievements. This manuscript aims to address the complexities of polio vaccine security within the context of the Immunization Agenda 2030 (IA2030) and the Global Polio Eradication Strategy 2022-2029, proposing actionable strategies to strengthen the vaccine supply. Methods: This manuscript analyzes obstacles to vaccine security, including supply disruptions and market uncertainties. It presents the Polio Vaccine Security Framework as a key strategy for addressing these challenges. Data were gathered from Global Polio Eradication Initiative (GPEI) reports, consultations with key stakeholders, and analyses of past vaccine shortages. Results: The findings indicate that the primary risks to vaccine security include the lack of a coherent long-term policy framework on polio vaccination, the absence of a clear polio vaccine development roadmap, and insufficient long-term, predictable forecasting. Additionally, stronger coordination is needed between stakeholders involved in vaccine supply, polio containment, and research, as well as addressing challenges related to financing and access to resources. Conclusions: A robust, adaptable, and sustainable approach to vaccine security, proposed in the Polio Vaccine Security Framework, is critical to achieving and sustaining polio eradication. Collaboration among policymakers, manufacturers, and stakeholders to implement it is essential to ensure the uninterrupted supply of polio vaccines, protecting the progress made over the past half century, and preventing a resurgence of poliovirus in the future.

Essential programme on immunization in WHO South-East Asia: A five-decade journey of saving millions of lives & ending diseases.

Vaccination is one of the most successful and cost-effective interventions designed by science which has helped in preventing millions of deaths, especially in children. The Expanded Programme on Immunization (EPI) was established by World Health Organization (WHO) in 1974 to develop immunization programmes throughout the world with polio, measles, diphtheria, tetanus, tuberculosis and whooping cough. The WHO South-East Asia Region (SEAR) has a disproportionately high burden of infectious diseases and has greatly benefitted from the EPI as compared to other regions with more than 90 per cent of the population having access to vaccines. The story of vaccines in South-East Asia is a testament to scientific progress, global collaboration, and unwavering commitment to public health. This article aims to discuss the journey of EPI in the WHO SEAR.

Navigating vaccine procurement and financing challenges in Cameroon: Insights and recommendations from a mixed-methods study (2015–2020)

ObjectivesVaccine stockouts at the national level has been recognized as a critical challenge in ensuring sustained and equitable immunization coverage. These stockouts often arise from inherent issues within countries, including delays in government funding, suboptimal forecasting and stock management practices, and inefficiencies in the procurement process amongst others. Understanding the complexities and barriers within vaccine procurement and financing systems is crucial for developing effective strategies to enhance vaccine availability and strengthen immunization programs. This is particularly relevant in the context of reaching zero dose children and transitioning from Gavi. This study aimed to comprehensively assess the vaccine procurement and financing landscape in Cameroon from 2015 to 2020. Study designThis was a descriptive cross-sectional study. MethodsEmploying a mixed-methods approach, we conducted a desk review of pertinent documents and engaged in in-depth interviews with key stakeholders involved in the procurement and funding mobilization processes. Through data collection and analysis using Microsoft Excel 365 and Dedoose software, we delineated the intricacies of the procurement process and pinpointed specific barriers that have contributed to vaccine stockouts. ResultsThe mapping of vaccine procurement processes revealed complexity, protracted timelines, and the involvement of multiple stakeholders. The Expanded Program on Immunization (EPI) faced a USD 4 million funding deficit for vaccine procurement between 2016 and 2019. Consequently, the program experienced delays in acquiring 20 million vaccine doses, leading to 41 months of stockout for at least one antigen. Major bottlenecks identified by key stakeholders in vaccine procurement and financing encompassed delayed fund mobilization, inefficient and lengthy processes for fund mobilization and disbursement, poor data utilization, and discrepancies between forecasted, allocated, and mobilized funds. ConclusionThe findings of this research hold significant implications for many EPIs. By elucidating procurement and financing challenges, we can formulate evidence-based recommendations aimed at optimizing resource allocation, streamlining procurement processes, and bolstering vaccine availability. These insights are essential for fostering collaboration between government agencies, technical partners, and financial partners to achieve sustainable vaccine access in Cameroon. Establishing a joint procurement working group could streamline processes, potentially reducing stockouts and improving vaccine coverage.

The cost of COVID-19 vaccine delivery in Bangladesh

ABSTRACT COVID-19 vaccination has been instrumental in fighting the pandemic, but evidence on the actual costs associated with delivering these vaccines in resource-constrained settings has been limited. We estimated the cost of delivering COVID-19 vaccines in Bangladesh through five delivery strategies in 2021 and 2022, including Ministry of Health (MOH) hospitals, non-MOH government hospitals, outreach at Expanded Program on Immunization (EPI) centers, mass campaigns, and schools. This was a bottom-up costing study, estimating costs from a payer and beneficiary perspective. We also mapped the funding flows for COVID-19 vaccination activities and analyzed programmatic and financial challenges. The economic cost incurred by the health system to deliver COVID-19 vaccines was $1.05 per dose, excluding vaccine costs. This was made up of a financial cost of $0.29 per dose and an opportunity cost of $0.75 per dose. School-based delivery incurred the lowest financial cost of $0.27, while outreach at EPI centers incurred the highest at $0.44 per dose. The low financial cost per dose is attributed to the high daily volumes delivered at sampled sites, minimal additional resources provided to sites to implement the COVID-19 vaccination program, and a reliance on the existing workforce. Beneficiaries spent an average of $1.63 to receive a single dose of COVID-19 vaccination at fixed sites, with transport representing the largest cost driver ($0.75 per dose). The economic cost to receive one dose of the COVID-19 vaccine was $4.78. Findings can support the Government of Bangladesh to make efficient and equitable resource allocation decisions for vaccination programs.

Economic, social, and administrative barriers to achieving the sustainable development goal of good health and well-being

Good health and well-being are embedded in the 3rd Goal amongst the UN Sustainable Development Goals. The primary objective of this research was to identify the most critical economic, social, and administrative barriers to implementing the Expanded Program on Immunization (EPI) in the Punjab Province of Pakistan. A sequential exploratory design and case study technique were used, employing both qualitative and quantitative methods. In the first stage, in-depth interviews with 50 key officials were conducted to identify the most critical barriers to the EPI program. A quantitative analysis was then performed based on the results obtained from qualitative analysis, and rank orders of barriers were received from the same health department experts. The results indicate that twenty-eight barriers can cause implementation problems for this program. Still, the ten barriers that gained the maximum hits are the most important barriers, which include Shortage of vaccinators, mismanagement of vaccines’ cold chain, biometric android application, ice-lined refrigerators, communication gap, inadequate legislation of EPI program, capacity building issues with EPI staff, Misconceptions about EPI program, lack of awareness of the parents and community, refusal cases and inadequate cooperation of lady health workers (LHWs). Coordinated efforts of the government and the public are highly recommended to address these barriers.

Spectrum and Incidence of Adverse Reactions Post Immunization in the Taiwanese Population (2014-2019): An Analysis Using the National Vaccine Injury Compensation Program.

Background: Post-marketing surveillance is crucial for gathering data on vaccine reactogenicity, enhancing public trust in immunization, and promoting vaccine uptake. This study aims to characterize adverse events following immunization (AEFIs) and estimate the incidence rates of adverse reactions (ARs) associated with vaccines included in Taiwan's Expanded Program on Immunization (EPI). This study utilizes data from Taiwan's Vaccine Injury Compensation Program (VICP). Methods: Vaccine injury claims submitted to the VICP between 2014 and 2019 were analyzed. ARs were defined as AEFIs adjudicated as "related" or "indeterminate" by the VICP committee. Data on the annual number of vaccine doses administered were obtained from the Taiwan CDC, which helped calculate the AR incidence rates. Results: A total of 491 AEFI claims were reviewed, with 327 (66.6%) categorized as ARs. The AEFIs were mainly associated with the Bacillus Calmette-Guérin (BCG) vaccine (43.4%) and the seasonal influenza vaccine (22.0%). Most EPI vaccines demonstrated low AR incidence rates, ranging from 1.68 to 13.6 per million doses, with the exception of BCG, which exhibited 162.5 ARs per million doses. Shifting BCG immunization from below 5 months to at least 5 months reduced osteomyelitis incidence significantly, from 41.4 to 7.9 (p = 0.0014), but increased abscess and lymphadenitis cases. Conclusions: EPI vaccines in Taiwan are highly safe, with minimal AR incidences in the general population. The BCG vaccine remains an exception, occasionally causing severe ARs like osteomyelitis. Adjusting the immunization schedule to an older age may mitigate some of these adverse effects.

Mass screening of hepatitis B and C in Burkina Faso: seroprevalence update and impact of hepatitis B vaccine.

Updated data on the seroprevalences of hepatitis B and C viruses (HBV, HCV) are required to enable the adaptation of control strategies. In this study, we aimed to: (i) estimate the seroprevalences of HBsAg carriers and HCV exposure in the general population, and (ii) determine the impact of vaccination on HBV circulation since its introduction in 2006 in the Expanded Program on Immunization (EPI). From October 2020 to October 2022, a mass screening campaign was conducted in 10 cities across Burkina Faso. Individuals of all ages and genders who consented to participate were screened for viral markers (HBsAg, anti-HCV) using rapid diagnostic tests. The proportions of HBsAg carriers and HCV exposure were calculated using Stata, and logistic regression was used to assess the impact of HBV vaccination on HBsAg carriage. A total of 15,650 participants were enrolled in the study. Of these, 51.4% were women and the age range was from 1 to 97 years. All participants were screened for HBsAg and 7,507 were also screened for anti-HCV. Overall, the seroprevalence of HBsAg was 8.8% and 2.6% for anti-HCV. The results indicated that age, gender, and place of residence were associated with HBV infection. The prevalence of HBV and HCV infections remains high in Burkina Faso. Prevention strategies, including initial mass screening with rapid diagnostic tests and vaccination, need to be intensified.

Impact of oral azithromycin and intermittent preventive treatment with sulfadoxine-pyrimethamine regimen on child mortality in Sierra Leone: trial protocol for a randomised, two-arm, double-blinded, placebo-controlled clinical trial (ICARIA)

BackgroundAzithromycin has been shown to be beneficial in preventing infectious diseases, including malaria, infectious diarrhoea and pneumonia. A cluster randomised control trial on azithromycin MDA in children in Niger, Malawi and Tanzania found a reduction in all-cause under-five (U5) mortality in communities who received azithromycin compared to placebo. However, the reduction was largest and statistically significant only in Niger. The purpose of this trial is to evaluate the impact of azithromycin plus intermittent preventive treatment in infants (IPTi), recently renamed by the World Health Organisation as perennial malaria chemoprevention (PMC), with sulfadoxine-pyrimethamine (SP) on all-cause mortality up to 18 months of age in children living in areas of high mortality burden through the Expanded Program on Immunisation (EPI) in Sierra Leone.MethodsThe Improving Care through Azithromycin Research for Infants in Africa (ICARIA) trial is a phase III two-arm, individually randomised, double-blinded, placebo-controlled trial administering oral AZI (20 mg/kg bodyweight) at three time points to children attending EPI visits in Sierra Leone. A total of 20,560 infants attending the first EPI contact at around 6 weeks of age are recruited and randomised to AZI or placebo in a 1:1 ratio. The second and third AZI/placebo doses are given at 9 and 15 months of age. The primary outcome of the trial is all-cause mortality rate at 18 months of age assessed through mortality surveillance. Other trial outcomes include the impact on antimicrobial resistance, and on the immune response to certain key routine EPI immunisations, the safety of the intervention, the prevalence of SP resistance markers and the feasibility, and acceptability of adding AZI to the EPI programme.DiscussionThe trial will provide the evidence needed to inform policy regarding the adoption and large-scale implementation of AZI in areas of high-mortality burden in sub-Saharan Africa.Trial registrationClinicalTrials.gov NCT04235816.

Demographic and pathogen characteristics of incident bacterial meningitis in infants in South Africa: A cohort study.

Bacterial meningitis is a major cause of death, with an approximate case fatality rate of 37% across all age groups in South Africa. This study aimed to describe the demographic and pathogen characteristics of incident meningitis in children aged <1 year in South Africa from 2014 through 2018, during a period when Haemophilus influenzae type b vaccine and pneumococcal conjugate vaccines (PCV) were both included in the expanded program on immunization (EPI). We conducted a cohort study of routine laboratory data in the National Health Laboratory Service Corporate Data Warehouse, which covers approximately 80% of the South African population. We defined a case of laboratory-confirmed bacterial meningitis as any person aged <1 year with meningitis diagnosed by culture and identification of a pathogen documented as being a common cause of meningitis in CSF. The cause-specific incidence risks were calculated by dividing the number of positive specimens in each age group and year by the corresponding mid-year population for children under 1 year old and those in the post-neonatal period (≥ 28 days to 365 days old). For children under 28 days old, the annual numbers of registered livebirths were used. We used Poisson regression to compare the incidence of meningitis by year. We identified 3575 (1.5%) cases of culture-confirmed bacterial meningitis from the 232,016 cerebrospinal fluid (CSF) specimens tested from 2014-2018. The highest number of cases were recorded in children aged <28 days (1873, 52.4%), male children (1800, 50.4%) as well as in the Gauteng Province (2014, 56.3%). Acinetobacter baumannii (14.9%), followed by Klebsiella pneumoniae (13.5%), and group B streptococcus (GBS) (10.7%), were the most common pathogens detected. Overall, A. baumannii had the highest incidence risk, occurring at 9.8 per 100,000 persons in children aged <1 year in 2018. Among neonates, A. baumannii peaked at 14.9 per 100,000 livebirths in 2018, while Streptococcus pneumoniae was most common in the post-neonatal period (≥ 28 days to 365 days old), peaking at 9.8 per 100,000 persons in 2014. There was an increase in the annual incidence of most pathogens over the study period. There was an increasing trend in the annual incidence of bacterial meningitis in infants caused by most pathogens, particularly A. baumannii, K. pneumoniae and GBS. In addition to increased uptake of vaccination, prevention measures to reduce nosocomial and mother-to-child transmission of bacteria could include antenatal screening for GBS in pregnant women, rigorous hygiene in the hospital environment as well as rational antibiotic use.

The role of big data analysis for resources optimization of immunization programmes in Pakistan.

Madam, The significance of Big Data Analysis (BDA) in optimizing immunization programmes in Pakistan emerges within the context of global and regional immunization challenges post the COVID-19 pandemic. Despite recovery efforts, a substantial number of children globally remain under-vaccinated, with 14.3 million zero-dose children in 2022.[1] South Asia, primarily India, has shown notable progress, exceeding pre-pandemic coverage levels.[2] In Pakistan, the Expanded Programme on Immunization (EPI) launched in 1978 aims to combat high under-five mortality rates due to vaccine-preventable diseases.[3] However, vaccine coverage remains suboptimal, with only 66% of children aged 12-23 months receiving basic EPI vaccines.[3] This is compounded by reduced doses administered later in schedules, influenced by limited access, awareness gaps, and insufficient vaccinators, especially in rural areas. [3] Big data analytics can help tackle challenges, improve resource allocation, and optimize immunization in Pakistan. The vital role of BDA in optimizing Pakistan's immunization programmes is rooted in its manifold health benefits. BDA aids disease prevention, identifies health risk factors, and enhances healthcare strategies.[4] Amid health emergencies like COVID-19, BDA leverages information technology to fortify health systems, enhancing decision-making, reducing errors, and conserving resources.[4] BDA's dynamic potential is evident. Its predictive tools swiftly pinpoint high-risk patients, streamlining care and elevating healthcare outcomes.[4] BDA draws insights from vast datasets for informed decisions. A recent study conducted in Sindh, increased vaccinator attendance from 44% to 88%, by factoring in results of BDA of Electronic Immunization Registries into their decision making.[5] BDA of antigen administration during accelerated outreach efforts revealed substantial boosts, compared to routine activities.[5] These findings spurred continued efforts in high-risk areas, showcasing BDA's impact in project acceleration and resource optimization.[5] This case highlights BDA's transformative role, enhancing immunization programs through data-driven insights. To harness the potential of BDA in immunization, Pakistan's healthcare system requires a digital overhaul. This entails prioritizing active patient data collection, storage, and analysis on a national scale. Collected data would facilitate targeted vaccination efforts in vulnerable areas. Storing data supports future research and predictive analysis, offering insights into current measures' efficacy and enabling necessary adjustments. A robust data analysis infrastructure, coupled with healthcare professional training, is essential. Cost-effective data security is vital. Digital registries in tertiary care hospitals and rural centres can aid government analysis. This holistic approach seeks to establish a digital healthcare ecosystem, involve the public, and implement data-driven solutions for improved immunization and overall public health in Pakistan.

Celebrating 50 years of Essential Programme on Immunization: What's achieved and what's next for the Eastern Mediterranean Region.

The year 2024 marks a pivotal moment in global health: it is the 50th anniversary of the Expanded Programme on Immunization (EPI). This extraordinary achievement is a testament to the power of collective action, scientific innovation and unwavering commitment to child health.

Assessment of expanded programme on immunization routine data quality in the upper east region of Ghana

BackgroundData quality is a major challenge for most health institutions and organizations across the globe. The Ghana Health Service, supported by other non-governmental organizations, has instituted various strategies to address and improve data quality issues in regional and district health facilities in Ghana. This study sought to assess routine data quality of Expanded Programme on Immunization, specifically for Penta 1 and Penta 3 vaccines.MethodsA descriptive cross-sectional study design was used for the study. A simple random sampling method was used to select thirty-four health facilities across seven sub-municipalities. Records from the Expanded Programme on Immunization (EPI) Tally Books and Monthly Vaccination Summary Report were reviewed and compared with data entered into the District Health Information Management System 2 (DHIMS2) software for the period of January to December 2020. The World Health Organization Data quality self-assessment (DQS) tool was used to compare data recorded in the EPI tally books with monthly data from summary reports and DHIMS2. Data accuracy ratio was determined by the data quality assessment tools and STATA version 14.2 was used to run additional analysis. A data discrepancy is when two corresponding data sets don’t match.ResultsThe results showed discrepancies between recounted tallies in EPI tally books and summary reports submitted as well as DHIMS2. Verification factor of 97.4% and 99.3% and a discrepancy rate of 2.6 and 0.7 for Penta 1 and Penta 3 respectively were recorded for tallied data and summary reports. A verification factor of 100.5% and 99.9% and a discrepancy of -0.5 and 0.1 respectively for the same antigens were obtained for the summary reports and DHIMS2. Data timeliness was 90.7% and completeness was 100% for both antigens.ConclusionThe accuracy of Penta 1 and Penta 3 data on EPI in the Upper East Region of Ghana was high. The data availability, timeliness and completeness were also high.

Revealing the challenges and efforts of routine immunization coverage in Nigeria.

Nigeria adopted the expanded program on immunization (EPI) in 1978, which aimed at offering children under 2 years old routine immunization (RI). Early accomplishments with the program resulted in a decrease in childhood mortality. As of 2018, Nigeria accounted for about 4.3 million out of over 13 million unvaccinated children globally. Therefore, this study revealed the challenges and efforts associated with RI program in Nigeria and the way forward. In this perspective article, I conducted searches and extracted relevant information from publicly available sources such as Google Scholar, Pubmed, and grey literature. I employed RI, challenges, efforts, and Nigeria as the keywords. The 2021 Multiple Indicator Cluster Survey/National Immunization Coverage Survey reports revealed weaknesses in the program, with a national average coverage of 36%. The primary barrier to EPI across various zones is the challenge of reaching marginalized areas that were cut off from vaccination services due to operational and sociocultural issues. Some of the obstacles, such as restricted access to medical facilities, weak cold chain systems, and COVID-19 containment strategies had a great impact on the RI program. To scale up the RI program, the Nigerian government, through the National Primary Health Care Development Agency (NPHCDA), collaborated with the World Health Organization (WHO) and Gavi, the Vaccine Alliance, to optimize the "Big Catch-up campaign" and increase immunization coverage nationwide. By 2028, 80% of the projected zero-dose populace is expected to be covered, reaching these eligible children with life-saving vaccines. Nigeria still has a long way to go in making significant progress in the RI program. To further strengthen the immunization coverage, the country needs to maintain data on their achievements, as this will help identify gaps that need to be addressed in the immunization program.
