Multiple-component interventions to increase rotavirus vaccine uptake in children: a randomised controlled trial

Rotavirus vaccine has not been included in the Hong Kong Government's Childhood Immunisation Programme. This randomised controlled trial examined whether a simple intervention package can increase rotavirus vaccine uptake in Hong Kong children. Postpartum mothers were recruited from two public hospitals in Hong Kong and randomly allocated into three groups using block randomisation, with block sizes kept unknown to investigators and research staff. Control-subjects received public rotavirus information. Subjects in intervention group 1 additionally received: key rotavirus information with a hyperlink to a webpage showing private clinics providing rotavirus vaccines and guidance on searching the clinics, and vaccination reminders. Subjects in intervention group 2 received the same intervention as group 1, plus tokens to receive free rotavirus vaccines at specific health centres. Rotavirus vaccination status was collected when children were approximately 8 months old. Maternal attitudes towards rotavirus vaccine were assessed at enrolment and at the end of the study. This trial has been registered in the Chinese Clinical Trial Register (Ref.:ChiCTR2000039791). From 16 February to 30 July 2021, 788 eligible mothers were recruited and randomly allocated to control group (n=263), intervention group 1 (n=263), and intervention group 2 (n=262). The full intervention package (intervention group 2 relative to control group) increased rotavirus vaccine uptake by 1.7 times (95% confidence interval [CI]=1.49-1.97) or by 33 percent-points (from 48% to 81% uptake). Provision of key rotavirus information with vaccination reminders (intervention group 1 relative to control group) and removal of financial barrier (intervention group 2 relative to intervention group 1) increased uptake by 1.17 times (95% CI=0.99-1.38) or 8 percent-points, and by 1.46 times (95% CI=1.29-1.66) or 25 percent-points, respectively. A multiple-component intervention package, and in particular providing free vaccine, could increase the uptake of rotavirus vaccine in Hong Kong children. The impact of the intervention package was greatest in low-income families, emphasising the importance of removing financial barriers to vaccination to promote equity. Incorporating rotavirus vaccine into the routine CIP could further protect more young children from rotavirus infection and improve equity. This work was supported by the Health and Medical Research Fund by the Health Bureau, Government of Hong Kong SAR [Ref.: 19180202].

IMMINENT CONTESTS AND SCENARIOS OF ROTAVIRUS VACCINATION IN PAKISTAN

Background: Rotavirus is one of the significant causes of gastroenteritis in children under the age of five years. Thousands of fatalities have occurred in low socioeconomic, underdeveloped countries. It is also an essential contributor to child death in Pakistan and a critical economic burden due to hospitalization. Objectives: The Extended Program on Immunization (EPI) in Pakistan planned to include a vaccine for rotavirus in a routine immunization program for children in two doses from October 2016. Methodology: The literature was searched using databases, including Google Scholar, Scopus, and PubMed. Results: Reports on vaccination coverage have revealed a number of problems associated with inadequate vaccination coverage, such as medical malpractice, neglect, illiteracy, community issues, and denials from parents on account of their child's illness, among other things. It is also impossible to keep the appropriate vaccination program going due to a lack of personnel needed for the precise delivery of the rotavirus vaccine. Conclusion: Including this vaccine will save the lives of approximately 29,000 children every year. However, the proper administration of the rotavirus vaccine to all children who are eligible for vaccination will be a real challenge to the government and health agencies in Pakistan.

Childhood vaccination among Polish immigrants in Norway: a qualitative study

BackgroundConfidence in childhood vaccination is high in Norway and the Norwegian Childhood Immunization Programme (NCIP) achieves high overall coverage rates. However, lower coverage has been observed for some immigrant groups, including Polish immigrants who represent the largest immigrant group in Norway. Anti-vaccine sentiments and increased refusal of mandatory childhood vaccination has been on the rise in Poland, but it is unknown whether such attitudes also apply to Polish immigrants in Norway, as they experience a different vaccination policy and perhaps also different attitudes to vaccines. This qualitative study aims to explore attitudes towards childhood vaccination in Norway among Polish immigrants.MethodsWe interviewed 15 Polish parents living in Norway in 2022. We recruited the participants by purposive sampling and analyzed the interviews by reflexive thematic analysis.ResultsThree themes were identified: views of childhood vaccination, vaccine hesitancy, and differences in childhood vaccination between Poland and Norway. Overall, the participants favored childhood vaccination and viewed most of the vaccines included in the NCIP as safe and reliable. Human papilloma virus, meningococcal and pneumococcal vaccines were declined by some of the parents. Comparisons of childhood vaccination in Poland and Norway was evident in many of the interviews, especially among parents whose children had received vaccines in both countries. The participants were well acquainted with the NCIP, favored voluntary childhood vaccination, and the majority expressed a high level of trust in Norwegian health authorities.ConclusionsPolish immigrants to Norway generally expressed positive views about childhood vaccination. Non-vaccination was related to lack of knowledge and/or unfamiliarity with certain vaccines and not with anti-vaccine sentiments or conspiracy theories. The study highlights how parents’ knowledge, in combination with norms and trends from both birth country and country of residence, influence parents’ decision making about vaccination.

The Impact of Vaccination Status on Anthropometric Indices of Growth Among Children: A Cross-Sectional Study.

Background Childhood immunization programs in underdeveloped nations can improve children's growth and nutritional status and prevent growth delays while protecting against infectious diseases and meeting growth norms. This study aimed toassess the impact of vaccination status on the anthropometric indices of children aged 12-18 months at an Expanded Programme on Immunization vaccination center and compare the anthropometric indices of growth in children with complete and incomplete vaccination statuses. Methodology This study was conducted at the rural health center in Kala Shah Kaku, Pakistan, from November 2023 to December 2023. Children aged 12-18 months were enrolled and their vaccination status was recorded. Height and weight were measured using World Health Organization growth charts. The data were analyzed using descriptive statistics and chi-square and Fisher's exact tests. A p-value <0.05 was considered statistically significant. Results The mean age of the 110 children who visited the vaccination site for this study was 16.36 months ± 2.415. There were 28 (25.5%) stunted children. In the study, 17.6 (16%) participants were underweight, and 15.95 (14.5%) were wasted. Of the children, 79% had received all recommended vaccinations. A statistically significant(p < 0.05) association was foundbetween vaccination and nutritional status. Conclusions This study emphasizes the significance of vaccination in promoting child health and nutrition, reducing stunting risk, and ensuring equitable access to vaccination services and comprehensive healthcare interventions. This can help mitigate the malnutrition burden and promote optimal growth, contributing to global health and development goals.

Comparative Analysis of Childhood Immunization Programmes in Northern Ireland and China

Childhood immunization programs play a crucial role in safeguarding public health by preventing the spread of infectious diseases. This report compares and contrasts the childhood immunization programs in Northern Ireland (NI) and China, assessing their impact on public health outcomes. The respective programs, existing findings on their impact, criteria for comparison, and outcomes are discussed. The analysis reveals both similarities and differences between the two programs, highlighting implications for policy recommendations.

Pneumococcal Carriage in Burkina Faso After 13-Valent Pneumococcal Conjugate Vaccine Introduction and Before a Schedule Change.

In October 2013, Burkina Faso introduced 13-valent pneumococcal conjugate vaccine (PCV13) into the routine childhood immunization program using 3 primary doses with no booster. Previous pneumococcal carriage studies showed reductions in vaccine-type (VT) carriage in children aged <5 years but not in older age groups. We conducted a cross-sectional, age-stratified pneumococcal carriage study among healthy persons aged ≥1 month in Bobo-Dioulasso in March 2020. Pneumococci isolated by culture from nasopharyngeal swabs (all participants) and oropharyngeal swabs (participants aged ≥5 years) were serotyped by polymerase chain reaction; a subset was serotyped by Quellung. Using data from a study with the same design from March 2017, we examined changes in pneumococcal carriage by age group. Among 1005 (2017) and 1002 (2020) enrolled participants, VT carriage decreased (21.6% to 15.9%; adjusted prevalence ratio [aPR], 0.76 [95% confidence interval {CI}, .63-.92]). By age group, decline in VT carriage was significant among children aged 5-14 years (28.9% to 16.3%; aPR, 0.57 [95% CI, .39-.84]) but not among children aged <5 years (22.4% to 19.1%; aPR, 0.87 [95% CI, .70-1.09]) or adults aged ≥15 years (12.0% to 5.5%; aPR, 0.52 [95% CI, .26-1.05]). Between 3 and 6 years after PCV13 introduction, significant declines in VT carriage were observed in older children, possibly reflecting indirect effects of PCV13 use. VT carriage in children aged <5 years remained stable with almost 1 in 5 carrying VT pneumococci, suggesting limitations to a PCV schedule without a booster dose.

Electronic Immunization Registry in Rwanda: Qualitative Study of Health Worker Experiences.

Monitoring childhood immunization programs is essential for health systems. Despite the introduction of an electronic immunization registry called e-Tracker in Rwanda, challenges such as lacking population denominators persist, leading to implausible reports of coverage rates of more than 100%. This study aimed to assess the extent to which the immunization e-Tracker responds to stakeholders' needs and identify key areas for improvement. In-depth interviews were conducted with all levels of e-Tracker users including immunization nurses, data managers, and supervisors from health facilities in 5 districts of Rwanda. We used an interview guide based on the constructs of the Human, Organization, and Technology-Fit (HOT-Fit) framework, and we analyzed and summarized our findings using the framework. Immunization nurses reported using the e-Tracker as a secondary data entry tool in addition to paper-based forms, which resulted in considerable dissatisfaction among nurses. While users acknowledged the potential of a digital tool compared to paper-based systems, they also reported the need for improvement of functionalities to support their work, such as digital client appointment lists, lists of defaulters, search and register functions, automated monthly reports, and linkages to birth notifications and the national identity system. Reducing dual documentation for users can improve e-Tracker use and user satisfaction. Our findings can help identify additional digital health interventions to support and strengthen the health information system for the immunization program.

Serotype epidemiology and antibiotic resistance of pneumococcal isolates colonizing infants in Botswana (2016-2019).

In 2012, Botswana introduced 13-valent pneumococcal conjugate vaccine (PCV-13) to its childhood immunization program in a 3+0 schedule, achieving coverage rates of above 90% by 2014. In other settings, PCV introduction has been followed by an increase in carriage or disease caused by non-vaccine serotypes, including some serotypes with a high prevalence of antibiotic resistance. We characterized the serotype epidemiology and antibiotic resistance of pneumococcal isolates cultured from nasopharyngeal samples collected from infants (≤12 months) in southeastern Botswana between 2016 and 2019. Capsular serotyping was performed using the Quellung reaction. E-tests were used to determine minimum inhibitory concentrations for common antibiotics. We cultured 264 pneumococcal isolates from samples collected from 150 infants. At the time of sample collection, 81% of infants had received at least one dose of PCV-13 and 53% had completed the three-dose series. PCV-13 serotypes accounted for 27% of isolates, with the most prevalent vaccine serotypes being 19F (n = 20, 8%), 19A (n = 16, 6%), and 6A (n = 10, 4%). The most frequently identified non-vaccine serotypes were 23B (n = 29, 11%), 21 (n = 12, 5%), and 16F (n = 11, 4%). Only three (1%) pneumococcal isolates were resistant to amoxicillin; however, we observed an increasing prevalence of penicillin resistance using the meningitis breakpoint (2016: 41%, 2019: 71%; Cochran-Armitage test for trend, p = 0.0003) and non-susceptibility to trimethoprim-sulfamethoxazole (2016: 55%, 2019: 79%; p = 0.04). Three (1%) isolates were multi-drug resistant. PCV-13 serotypes accounted for a substantial proportion of isolates colonizing infants in Botswana during a four-year period starting four years after vaccine introduction. A low prevalence of amoxicillin resistance supports its continued use as the first-line agent for non-meningeal pneumococcal infections. The observed increase in penicillin resistance at the meningitis breakpoint and the low prevalence of resistance to ceftriaxone supports use of third-generation cephalosporins for empirical treatment of suspected bacterial meningitis.

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.

Vaccine coverage among children born to immigrant parents in Norway, 2000–2020

BackgroundThe Norwegian Childhood Immunization Program maintains a high national coverage of 95–97% in the most recent years. Whether there are subgroups with lower uptake is less studied. This study examines pertussis and measles vaccination coverage among six immigrant groups in Norway. These vaccines are normally administered as part of different combination vaccines and their coverage rate indicate the national vaccination coverage against a range of additional infections. MethodsData from the Norwegian National Population Register were linked at individual level with vaccination data from the Norwegian Immunisation Registry. The final sample consisted of 53,052 children born during 2000–2018 in Norway to parents who were born in Iraq, Lithuania, Pakistan, Poland, Somalia, or Vietnam. Vaccination coverage was measured at 2-years of age. Multivariate linear regression was utilized to estimate the relationship between vaccinations status, year of birth, gender, mother’s length of residency in Norway, and area of residence. ResultsAt two years of age, the majority of the children were vaccinated. Coverage among the groups varied at, above, and below the national average for the two vaccines. For most of the years examined, children born by parents from Lithuania, Poland, and Somalia had lower coverage for the measles vaccine (range 81–84% in 2020) than the national level (97% in 2020). Children born by parents from the Eastern-European countries also had lower coverage than the national level for the pertussis vaccine (range 87–89% in 2020). DiscussionThis study illustrates how subgroups with lower vaccination coverage may exists within a well-established vaccination program with high national coverages. Differences in coverage were found for both vaccines, but the differences were more pronounced for the measles vaccine. The high vaccination coverage in Norway provides indirect protection through herd immunity for unvaccinated individuals, however, the lower vaccination coverage in some immigrant groups is a concern.

COVID-19 vaccines: history of the pandemic’s great scientific success and flawed policy implementation

The COVID-19 vaccine has been a miraculous, life-saving advance, offering staggering efficacy in adults, and was developed with astonishing speed. The time from sequencing the virus to authorizing the first COVID-19 vaccine was so brisk even the optimists appear close-minded. Yet, simultaneously, United States’ COVID-19 vaccination roll-out and related policies have contained missed opportunities, errors, run counter to evidence-based medicine, and revealed limitations in the judgment of public policymakers. Misplaced utilization, contradictory messaging, and poor deployment in those who would benefit most—the elderly and high-risk—alongside unrealistic messaging, exaggeration, and coercion in those who benefit least—young, healthy Americans—is at the heart. It is important to consider the history of COVID-19 vaccines to identify where we succeeded and where we failed, and the effects that these errors may have more broadly on vaccination hesitancy and routine childhood immunization programs in the decades to come.

Impact of COVID-19 Pandemic on Routine Childhood Immunization Programs in Indonesia: Taking Rural and Urban Area into Account.

To date, the primary global concern has revolved around addressing the COVID-19 pandemic. However, there is a growing awareness of the pandemic's secondary impacts on critical aspects of healthcare, such as childhood immunization programs. This study aims to assess the impact of the COVID-19 pandemic on childhood immunization programs in Indonesia, with a specific focus on performance disparities between rural and urban areas. It considers factors like access, utilization, and program workload. Data were collected from primary health cares (PHCs) in two regions in West Java Province, Indonesia, representing rural and urban areas. A descriptive analysis was conducted to compare vaccination coverage, drop-out rates, and the ratio of vaccinators per dose from 2019 to 2021 in 40 and 22 PHCs for rural and urban areas, respectively. A general linear model was employed to evaluate the differences in these parameters over the three consecutive years. The results indicate fluctuations in vaccine coverage over the three years, with the most significant impact observed in 2020, particularly in rural areas. Statistical analysis revealed a significant difference in routine immunization coverage, drop-out rates, and vaccinator ratios between rural and urban areas from 2019 to 2021 (p<0.05). In 2021, both rural and urban areas displayed significant differences in performance parameters for routine immunization and COVID-19 vaccination (p<0.05), except in terms of coverage for IPV and COVID-19 vaccination. The study highlights a reduction in routine immunization coverage during the pandemic, a concerning issue that increases the risk of vaccine-preventable diseases, particularly in rural areas.

Seroepidemiological analysis of hepatitis B virus infection among adolescents aged 0-14 years in Henan Province and preliminary evaluation of the effectiveness of childhood hepatitis B vaccine immunization program

Objective: To analyze the seroepidemiological characteristics of hepatitis B virus (HBV) infection among adolescents aged 0-14 years in Henan Province and to evaluate the effectiveness of the childhood hepatitis B vaccine (HepB) immunization program. Methods: From September 2021 to March 2022, a total of 4 883 adolescents aged 0-14 years were selected from 25 villages or communities of 18 provincial-level cities in Henan Province by using the multi-stage random cluster sampling method. Demographic data were collected through questionnaires. The 3 ml of blood samples were collected from individuals aged 0-4 years and 5 ml of blood samples were collected from individuals aged 5-14 years to test HBsAg, HBcAb and HBsAb. Data on vaccination were collected through Henan Provincial Immunization Information System and hepatitis B cases in Henan Province were collected through China Infectious Disease Reporting System. The effectiveness of the childhood HepB immunization program was analyzed. Results: The average age of 4 883 subjects was (7.32±2.81) years old. The positive rates of HBsAg and HBcAb were 0.1% (7/4 883) and 1.0% (50/4 883), and the population standardized rates were 0.3% and 1.7%. In 2002, the positive rate of HBsAg among adolescents aged 0-14 years in Henan Province was 3.39%. Compared with that in 2002, the number of chronic HBV infections among adolescents in Henan Province in 2022 decreased by about 0.7 million. In 2002, the vaccination rate of newborns who completed all three doses of vaccine was 6.26%. In 2003, the vaccination rate of the hepatitis B vaccine rose rapidly, reaching 90% in 2013 for the first time. After 2014, the vaccination rate in Henan Province continued to remain above 95%. The proportion of cases among children aged 1-4 years in clinical reports decreased from 0.43% (1 108/256 566) in 2006 to 0.01% (78/80 655) in 2021. The proportion of cases among adolescents aged 5-19 years decreased from 18.21% (46 710/256 566) in 2006 to 1.1% (827/80 655) in 2021. Conclusions: From 2002 to 2022, the positive rate of HBsAg among adolescents aged 0-14 years has decreased significantly in Henan Province. The effectiveness of the HepB immunization program for children is good.

Assessing the relationship between existing childhood, adolescent and adult immunization programmes and national COVID-19 vaccination capacities in 2021

BackgroundDuring the COVID-19 pandemic, nearly all countries introduced COVID-19 vaccination programmes. Yet, countries had a wide range of programmatic experiences. This analysis aims to identify national characteristics associated with COVID-19 vaccination programmatic success. MethodsWe used the following outcome measures: the presence of national COVID-19 vaccination capacities and COVID-19 coverage as of December 2021, June 2022, and December 2022. We developed a standardized metric for assessing national COVID-19 vaccination capacities as a proxy for speed of introduction. We developed this metric through adaptation of the WHO Guide for Conducting an Expanded Programme on Immunization Review and consultations with technical experts specializing in vaccine introduction and emergency deployment; monitoring and data; childhood, adolescent and adult programmes; and COVID-19 vaccination roll-out. Through multivariable linear regressions, we evaluated whether having a mature immunization programme for children, adolescents and adults; recent use of emergency vaccination; World Bank income classification; past early adoption of new vaccines; density of the health workforce; and/or trust in science and government were associated with higher COVID-19 vaccination capacities and coverage. ResultsThe COVID-19 vaccination capacities scores ranged from 0 to 5 points with a global median score of 2 and an interquartile range of 1;4. After adjusting for World Bank income classifications, the presence of a mature influenza vaccination programme was independently correlated with statistically significant higher scores of national COVID-19 vaccination capacities and higher COVID-19 vaccination coverage in December 2021, June 2022, and December 2022. Trust in government was also associated with higher coverage for all three time stamps. ConclusionsAs countries consider how to prepare for and respond to future pandemics, having an adult seasonal influenza vaccination programme, building trust in government, and ensuring equitable access to vaccines supply emerged as key aspects that can benefit from additional national and global focus.

Sustainability of pneumococcal conjugate vaccination in Ghana: a cost-effectiveness analysis in the context of donor transition.

Streptococcus pneumonia is responsible for 18% of infant deaths in Ghana. With co-financing from Gavi in 2012, Ghana introduced the PCV13 into the childhood immunization programme to reduce the burden of Streptococcus pneumonia. However, Ghana will graduate to the Gavi fully self-financing phase in 2026, when the nation assumes full responsibility of paying for the PCV13. This research aims to evaluate the health impact and cost-effectiveness of PCV13 immunization in Ghana since its implementation and after the cessation of support from Gavi. We used the UNIVAC tool to evaluate two main scenarios of cost-effectiveness, from vaccine introduction (2012-2025) and after Gavi transition (2026-2031) in comparison with no vaccination. The sources of data include national data, international estimates and expert opinion. Cost was considered from both the government and societal perspectives. We discounted health outcomes at 3%. Currency values were stated in US Dollars. We tested the robustness of the base case results by performing scenario and sensitivity analyses. PCV13 will reduce the pneumococcal disease burden by 48% from 2012 to 2031. The vaccination programme costs are USD 130 million and USD 275 million in 2012-2025 and 2026-2031 respectively. It also has a budget impact of USD 280 million for the 2026-2031 period from the perspective of government. The incremental cost-effectiveness ratios are USD 89 and USD 73 respectively from the perspectives of government and society in 2012-2025. The incremental cost-effectiveness ratios are USD 530 and USD 510 respectively from the perspectives of government and society in 2026-2031. The PCV13 vaccination programme in Ghana is cost-effective at 50% GDP per capita threshold even when Gavi withdraws co-financing support from 2026 onwards.

Recurrent diphtheria outbreaks in Nigeria: A review of the underlying factors and remedies.

The introduction of the diphtheria-tetanus-pertussis (DTP) vaccine into childhood immunization programs resulted in its widespread elimination in high-income countries. However, Nigeria is currently experiencing an outbreak. The primary cause of diphtheria outbreaks and its high mortality rates in Nigeria was waning herd immunity due to low DTP coverage and a lack of diphtheria antitoxin (DAT), respectively. However, the underlying causes of Nigeria's low DTP coverage and DAT supply remain unknown. Relevant studies and reports included in our review were obtained by a search through Google Scholar, PubMed, and organization websites using the terms "Diphtheria-Pertussis-Tetanus vaccine OR Diphtheria antitoxin and Nigeria OR Diphtheria Outbreak." All articles considering diphtheria outbreaks, DTP vaccine, and DAT supply in Nigeria were considered without time restriction due to the paucity of data. We used the narrative synthesis approach to critically appraise, analyze, and draw inferences from the selected articles. The main causes of low DTP coverage are insufficient supply, an inefficient cold chain system, and low uptake due to poor health literacy and negative sociocultural and religious beliefs, whereas the key barriers to DAT availability are insufficient production by pharmaceutical industries because of low demand and priority. The underlying causes of Nigeria's low DTP coverage and DAT supply are multifactorial. Both short-term and long-term measures are needed to control this outbreak and prevent future occurrences.

Vaccination compliance of selected childhood immunization programs and the socio-determinant factors in Nigeria

Introduction: Adherence to full vaccination is important in preventing childhood diseases. The aim of this study was to evaluate the level of compliance to full vaccination and identify the socio-cultural factors associated with full vaccination compliance in children. Methodology: The socioeconomic variables associated with each of the four binary dependent variables of whether or not a child is fully vaccinated against tetanus, BCG, measles, and pentavalent were determined using logistic regression. Results: While compliance to full tetanus and BCG vaccinations was &gt; 60% at the national level, less than 50% and 10% full vaccination compliance were recorded for pentavalent and measles vaccinations, respectively. The South East region of Nigeria recorded the overall highest full vaccination compliance while the least performing region was the North West zone. The mother or guardian literacy level, employment status, antenatal care attendance, and internet usage were strong predictors of full vaccination compliance (p &lt; 0.05). Conclusions: The socio-cultural factors associated with achieving full vaccination coverage in Nigeria in this study should drive the implementation of policies that will be best suited to each geopolitical zone of Nigeria.
