Spatial distribution and determinants of measles vaccination dropout among under-five children in Ethiopia: A spatial and multilevel analysis of 2019 Ethiopian demographic and health survey

BACKGROUND

Each year, vaccine-preventable diseases cost the lives of 8.8 million under-five children. Although vaccination prevents 1-2 million childhood deaths worldwide, measles vaccination dropouts are not well studied in developing countries, particularly in Ethiopia. Therefore, this study aims to assess the spatial distribution of the measles vaccination dropout and its determinants among under-five children in Ethiopia.

METHODS

Data from Ethiopian Demographic and Health Survey 2019 was used for data analysis. The study used a total of 5,753 children. Spatial autocorrelations was used to determine the spatial dependency of measles vaccination dropout. Ordinary interpolation was employed to forecast measles vaccination dropout. Factors associated with measles vaccination dropout were declared significant at p-values <0.05. The data were interpreted using the confidence interval and adjusted odds ratio. A model with the lowest deviance and highest logliklihood ratio was selected as the best-fit model.

RESULTS

In Ethiopia, one in three under-five children had measles vaccination dropouts. Factors such as birth interval (AOR = 1.87, 95% CI: 1.30, 2.70), unmarried marital status women (AOR = 3.98, 95% CI: 1.08, 8.45), ≤1 number of under-five children (AOR = 3.86, 95% CI: 2.56, 5.81), rural place of residence (AOR = 2.43, 95% CI: 2.29, 3.11), low community-level ANC utilization (AOR = 3.20, 95% CI: 2.53, 3.56), and residing in Benishangul Gumuz (AOR = 1.80, 95% CI: 1.061, 3.06) had higher odds of measles vaccination dropout.

CONCLUSIONS

Measles vaccination dropout rates in Ethiopia among under-five children were high compared to the maximum tolerable vaccination dropout level of 10% by the WHO. Both individual and community-level variables were determinants of measles vaccination dropout. The ministry of health in Ethiopia should give attention to those mothers of under-five children who reported underutilization of ANC services and rural residences while designing policies and strategies in areas of high spatial clustering of vaccine dropout in Ethiopia.

Referrals and Determinant Factors of a National School Health Campaign in Lebanon on Children Aged between 3 and 12 Years Old

In this extensive study examining the health of 7184 school children aged 3 to 12 in 27 Lebanese schools, screenings involved medical evaluation and interviews, complemented by phone interviews with 3880 parents. Notably, one in two students received a medical referral, revealing prevalent issues such as dental cavities (33%), under-vaccination (25%), undetected vision problems (13%), abnormal growth (6%), underweight (27%), and overweight (33%). Additional concerns encompassed abnormal vital signs (3%), abuse signs (0.6%), infectious skin lesions (1.6%), scoliosis (1.7%), abnormal auscultation (heart 1.1%, lungs 1.2%), ear problems (3.3%), precocious puberty (0.7%), and neurologic signs (0.6%). Mental health challenges affected 20-25% of students. Public schools and Beirut exhibited higher referral rates, with girls, older children, overweight students, those lacking regular pediatrician visits, and children of self-employed or less educated parents facing elevated referral rates. In contrast, children of healthcare workers experienced fewer referrals. Against this backdrop, the study emphasizes the imperative for targeted health initiatives, particularly in marginalized areas and for socioeconomically disadvantaged students. Priority areas include dental care, weight issues, mental health, vaccination compliance, and addressing vision problems to enhance learning outcomes.

Determinants of influenza and COVID-19 vaccine intent or uptake in Lebanon: a scoping review of the literature

BACKGROUND

Vaccination is essential to protect from influenza and recently from COVID-19, yet uptake in Lebanon is suboptimal. Several factors determine uptake including knowledge, attitude and policies. We conducted a scoping review of the literature to explore the determinants of influenza and COVID-19 vaccine intent or uptake in Lebanon.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, thirty one peer reviewed studies indexed in six databases Pub Med, EMBASE, Scopus, CINAHL, Medline, and the Cochrane Library were screened. Two students, a senior Librarian and an Associate Professor in nursing searched for eligible studies. The library search strategy followed a combination of three broad concepts (viral influenzas; vaccines; Lebanon). The search timeframe was up till December 31, 2022. Determinants of influenza and COVID-19 vaccine intent or uptake were categorized following the constructs of the Theory of Planned Behavior.

RESULTS

Nine studies investigated influenza vaccine intent or uptake among the public community, parents and healthcare workers. Twenty one studies investigated COVID-19 vaccine intent or uptake among the public community, older refugees, university students, patients with cancer, dentists, and social media users. One study investigated both types of vaccines. A conceptual model of the determinants of vaccine intent and uptake within the Lebanese context was developed. Various determinants included environmental factors, norms, knowledge, perceptions, attitudes, past experiences, behavioral control and hesitancy.

CONCLUSIONS

Research on vaccine intent and uptake in Lebanon is still in its infancy, while that of COVID-19 is on the rise. Multifaceted reasons behind the low vaccination rates were observed yet few attempts were made to target vulnerable groups. Further research studies are needed to target vulnerable groups.

Perceptions of, and Obstacles to, SARS-CoV-2 Vaccination Among Adults in Lebanon: Cross-sectional Online Survey

BACKGROUND

The COVID-19 pandemic is an additional burden on Lebanon's fragmented health care system and adds to its ongoing political, economic, and refugee crises. Vaccination is an important means of reducing the impact of the pandemic.

OBJECTIVE

Our study's aims were to (1) assess the prevalences of intention to vaccinate and vaccine hesitancy in Lebanon; (2) determine how vaccine hesitancy in Lebanon varies by sociodemographic, economic, and geographic characteristics; and (3) understand individuals' motivations for vaccinating as well as concerns and obstacles to vaccination.

METHODS

We performed a cross-sectional study from January 29, 2021, to March 11, 2021, using an online questionnaire of open- and closed-ended questions in Arabic via convenience "snowball" sampling to assess the perceptions of adults residing in Lebanon.

RESULTS

Of the 1185 adults who participated in the survey, 46.1% (95% CI: 43.2%-49.0%) intended to receive the SARS-CoV-2 vaccine when available to them, 19.0% (95% CI 16.8%-21.4%) indicated they would not, and 34.0% (95% CI 31.3%-36.8%) were unsure (with an additional 0.9% skipping this question). The most common reasons for hesitancy were concerns about safety, limited testing, side effects, and efficacy. Top motivations for vaccinating were to protect oneself, protect one's family and the public, and end the pandemic. Despite financial hardships in Lebanon, barriers to vaccine access were not frequently described as concerns. Established health care facilities, rather than new temporary vaccination centers, were most frequently selected as preferred vaccination sites.

CONCLUSIONS

Vaccine hesitancy appears to be high in Lebanon. Disseminating clear, consistent, evidence-based safety and efficacy information on vaccines may help reduce vaccine hesitancy, especially among the large proportion of adults who appear to be unsure about (rather than opposed to) vaccination.

Factors influencing the occurrence of infectious disease outbreaks in Lebanon since the Syrian crisis

Since the beginning of the Syrian crisis in 2011, the region has witnessed a major population displacement. Lebanon, a country with a population of 4.2 million, has welcomed around one million refugees. A rise in the incidence of Measles, Hepatitis A and Leishmaniosis was noted. This paper aims to document the incidence of outbreaks along with the factors that contributed to their emergence in Lebanon. A comprehensive literature review was conducted using electronic databases and (non) governmental reports, including studies reporting the state of Syrian refugees in Lebanon and those reporting on infectious outbreaks in Lebanon and Syria. Primary outcomes were defined as incidence or prevalence of Measles, Hepatitis A, and Leishmaniosis in both populations. Secondary outcomes were set to be the risk factors for the outbreaks. As of February 2016, Lebanon registered a total of 1.067.785 refugees. Infectious outbreaks were reported in Lebanon just after initiation of Syrian migration, with 1760 new measles cases, 1551 hepatitis A cases, and 1033 Leishmania cases in 2013. Local factors probably contributing to the emergence and dissemination of the outbreaks include living conditions, water and sanitation, nutritional state, and immunization. The outbreaks were not only reported in regions with higher refugee concentration, but also within other Lebanese regions. This was attributed to deficiencies in immunization of measles, low socioeconomic status and poor living conditions. The Syrian crisis has led to considerable impact on the demographic, economic, and political systems in Lebanon, next to an important burden on the healthcare system.

Charting mandatory childhood vaccination policies worldwide

Mandatory childhood vaccination is becoming an increasingly important policy intervention for governments trying to address low vaccination rates. Mandates require vaccination for a certain purpose, most commonly related to school entry for children. However, the discussion surrounding the extent and impact of mandatory vaccination programmes for babies and children have largely been limited to high-income countries. While many recent publications discuss the issue, they have not been inclusive of low- and middle-income countries. This paper thus presents a comprehensive and updatable database of mandatory childhood vaccination policies worldwide, covering 149 countries. The list indicates whether a country has a mandatory vaccination policy and the strictness of the mandate on a scale ranging across three levels of mandatory, mandatory for school entry or recommended. It draws on extensive desk-based research analysing a variety of sources, supplemented by consultations with experts from various health authorities. The paper provides an overview of the state of mandatory childhood vaccination across different World Health Organization (WHO) regions and with country case studies, setting out the general trends and issues, and engages with a discussion about why, how, and where mandatory vaccination is put in place. Our findings show in-country variation in vaccination policy and a variation between vaccination in policy compared to in practice. We observe, particularly for high-income countries, that the occurrence of recent outbreaks is a major factor for the introduction of mandatory vaccination. Also, many low- and middle- income countries have resorted to mandatory vaccination policies because of a lack of other policy options yet still have lower than targeted vaccination rates due to problems with vaccine supply, delivery, and access. Offering comparisons between countries will provide a useful tool for government decision-makers considering the merits of mandatory vaccination.

Predictors of immunization coverage among 12-23 month old children in Ethiopia: systematic review and meta-analysis

BACKGROUND

Immunization is one of modern medicine's greatest achievements in the last three decades. Annually it can prevent nearly 2 to 3 million deaths. Understanding the determinants of effective immunization coverage is a critical undertaking. Accordingly, we set out to check the best available evidence of outstanding predictors of immunization coverage among children aged 12-23 months in Ethiopia.

METHOD

Electronic databases including PubMed, Google Scholar, HINARI, and SCOPUS, Web of Science, African Journals Online, Ethiopian Medical Journals were searched. The search process, study selection, critical appraisal, and data extraction were done independently by two reviewers using Joanna Briggs Institute Meta-analysis for Review Instrument (JBI-MAStARI). The difference between reviewers was resolved with a third person. The risk of bias was assessed by the Newcastle Ottawa Tool for observational studies. Data were extracted using the Microsoft Excel checklist and exported to STATA 13. Heterogeneity was assessed using I2, Funnel plot and Egger's test was used to check for publication bias.

RESULTS

We identified 26 studies with 15,042 children with mothers/caretakers to assess factors associated with immunization coverage and significant factors were: maternal formal education, (OR = 2.45; 95% CI: 1.62-3.72), paternal formal education, (OR = 1.01; 95% CI: 0.27-3.77), residence, (OR = 2.11; 95% CI: 1.00-4.45), birth at health facility (OR = 1.86; 95% CI: 0.99-3.49), family size less than four, (OR = 1.81; 95% CI: 1.16-2.84), knowledge on age of immunization to be completed (OR = 6.18;95% CI: 3.07-12.43), knowledge on immunization schedule (OR = 2.49; 95% CI: 1.35-4.59), time to travel to health faculties, (OR = 1.74; 95% CI: 0.62-4.89), antennal care, (OR = 3.11; 95% CI: 1.64-5.88), and tetanus toxoid vaccination, (OR = 4.82; 95% CI: 2.99-7.75).

CONCLUSION

Our findings showed that literacy, residence, awareness, family size, maternal health services use, and proximity of the health facilities were factors associated with full immunization. This implies that there is a need for primary health service expansion and health education to "hard to reach areas" to improve immunization coverage for children aged 12-23 months.

Epidemiology of bacterial meningitis in Lebanon from 2011 to 2019

BACKGROUND

Meningitis is a clinical syndrome, characterized by the inflammation of the meninges, the protective tissues that envelop the brain and spinal cord. It can be due to bacterial, viraland even fungal pathogens.

OBJECTIVES

This study's aim is to investigate and observe the different aspects of meningitis in Lebanon between 2011 and 2019, specifically bacterial meningitis, and compare the incidence rates to different countries.

MATERIALS AND METHODS

This study is a descriptive epidemiological study. Data were collected from the epidemiological surveillance unit of the Lebanese Ministry of Public Health. Incidence according to year, months, age groups, governorates and causative agents were analyzed in the 9-years period.

RESULTS

With an incidence rate of approximately 7.56 cases a year per 100,000 individuals, bacterial meningitis accounted for most of the meningitis cases from 2011 to 2019. Four of the most commonly identified bacterial pathogens were studied: Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, and Mycobacterium tuberculosis, as well as other cases of meningitis with an identified or unidentified agent. The most common identifiable pathogen was S. pneumoniae (13.06%), followed by N. meningitidis (7.09%), and H. influenzae (0.56%).

CONCLUSION

The data provided by the MOPH was evaluated in order to get a better understanding of the disease and improve the plans of action towards its control and treatment. Efforts should be made to preserve and ameliorate the existing surveillance system, and to ensure that all cases of meningitis are reported and investigated in compliance with the WHO guidelines.

Parents' knowledge, attitude and practice towards children's vaccination in Lebanon: role of the parent-physician communication

Background

One of the most effective public health interventions in the world is immunization. However, some parents doubt its usefulness and safety. Many factors influence their decision to vaccinate, including their sociodemographic characteristics, their trust in the public health system, the parent-physician relationship, their level of knowledge and their attitudes towards vaccination. Our objective was to determine the factors, especially the parent-physician communication, associated with parental knowledge, attitudes and practices of their children’s vaccination.

Methods

Three thousand five hundred parents (father, mother or both) of children aged between 1 month and 15 years were approached by a trained personnel who performed the data collection through personal interviews (February–April 2019).

Results

The response rate was 79.5%. The results of the multivariable analysis showed that a better patient-physician communication was significantly associated with higher knowledge, better attitude and practice. Better knowledge was significantly associated with better attitude, whereas better knowledge and attitude were significantly associated with better practice.

Conclusion

Our study shows the importance of good physician-patient communication in improving knowledge, attitude and practice of parents towards their children’s vaccination.

Measles and mumps outbreaks in Lebanon: trends and links

BACKGROUND

Lebanon has experienced several measles and mumps outbreaks in the past 20 years. In this article, a case-based surveillance of both measles and mumps outbreaks in Lebanon was carried out in an attempt to outline factors contributing to the failure of elimination plans and to provide potential solutions. The relationship between the outbreaks of both diseases was described and explored.

METHODS

A retrospective descriptive study of confirmed cases of measles and mumps in Lebanon between 2003 and 2018 collected from the Lebanese Ministry of Public Health Epidemiological Surveillance Unit public database was carried out. The information collected was graphically represented taking into consideration dates of reported cases, age groups affected, and vaccination status.

RESULTS

The mean number of measles cases was 150.25 cases/year in the 1-4 years age group, 87 cases/year in individuals aging between 5 and 14, and 63.68 cases/year in those > 14 years old. In the latter group, only 18.05% were unvaccinated. The mean number of mumps cases was 30.4 cases/year in the < 4 year age group and 53.8 cases/year in the 10-19 years age group. During the study period, every spike in measles cases was followed by a similar spike in mumps. 9.66% of measles cases occurred in individuals who received at least 2 doses of the vaccine, 52.26% in the unvaccinated, and 38% in those whose vaccination status was undetermined.

CONCLUSIONS

Measles in Lebanon is a disease of the pediatric population, but adults remain at risk. Outbreaks of mumps followed those of measles and were mainly among adolescents. Presence of a large number of Syrian refugees in the country may further complicate the situation. Vaccination activities need to be intensified.
