Vaccination Coverage Cluster Surveys in Middle Dreib - Akkar, Lebanon: Comparison of Vaccination Coverage in Children Aged 12-59 Months Pre- and Post-Vaccination Campaign.

ABSTRACT:

Introduction

With the high proportion of refugee population throughout Lebanon and continuous population movement, it is sensible to believe that, in particular vulnerable areas, vaccination coverage may not be at an optimal level. Therefore, we assessed the vaccination coverage in children under 5 in a district of the Akkar governorate before and after a vaccination campaign. During the vaccination campaign, conducted in August 2015, 2,509 children were vaccinated.

Materials and methods

We conducted a pre- and post-vaccination campaign coverage surveys adapting the WHO EPI cluster survey to the Lebanese MoPH vaccination calendar. Percentages of coverage for each dose of each vaccine were calculated for both surveys. Factors associated with complete vaccination were explored.

Results

Comparing the pre- with the post-campaign surveys, coverage for polio vaccine increased from 51.9% to 84.3%, for Pentavalent from 49.0% to 71.9%, for MMR from 36.2% to 61.0%, while the percentage of children with fully updated vaccination calendar increased from 32.9% to 53.8%. While Lebanese children were found to be better covered for some antigens compared to Syrians at the first survey, this difference disappeared at the post-campaign survey. Awareness and logistic obstacles were the primary reported causes of not complete vaccination in both surveys.

Discussion

Vaccination campaigns remain a quick and effective approach to increase vaccination coverage in crisis-affected areas. However, campaigns cannot be considered as a replacement of routine vaccination services to maintain a good level of coverage.

Project description:BACKGROUND:Vaccination is one of the most cost-effective means of public health interventions to prevent childhood deaths from infectious diseases. Although several fragmented studies have been conducted concerning full vaccination coverage among children aged 12-23 months in Ethiopia, the pooled estimate has not been determined so far. Therefore, this systematic review and meta-analysis aims to estimate the pooled prevalence of full vaccination coverage among children aged 12-23 months in Ethiopian. METHODS:To find potentially relevant studies, we systematically searched five major databases (i.e., PubMed/MEDLINE, CINAHL, EMBASE, Google Scholar, and Science Direct). This review included community based cross-sectional studies reported in English language; had good quality, and published from the 1st of January 2000 to the 20th of November 2019. Data were analyzed using Stata™ Version 14.1 software. The pooled estimates with 95% confidence intervals (CIs) were presented using forest plots. Higgins and Egger's tests were used to assess heterogeneity and publication bias, respectively. Primary estimates were pooled using a random effects meta-analysis model. RESULTS:Of the total of 851 identified articles 21 studies involving 12,094 children met the inclusion criteria and were included in this meta-analysis. The included studies sample size ranged from 173 to 923. The lowest proportion of full vaccination coverage was reported from Afar Region [21% (95% CI: 18, 24%)], whereas the highest proportion of full vaccination coverage was reported from Amhara Region [73% (95% CI: 67, 79%)]. The overall prevalence of full vaccination coverage among children in Ethiopia was 60% (95% CI: 51, 69%). CONCLUSIONS:Our finding suggested that six in every 10 children in Ethiopia were fully vaccinated. However, this finding is much lower than the World Health Organization recommended rate. Moreover, high regional variations in terms of full vaccination coverage across the country was observed. Therefore, a special attention should be given to improve the overall childhood vaccination coverage.

Project description:BackgroundVaccination is one of the effective ways to develop immunity against potential life-threatening diseases in children in early age. This study is focused on analysing the age-appropriate vaccination coverage at national and subnational levels and identify the factors associated with age-appropriate coverage in Nepal.Methods460 children aged 12-36 months were included in the study. The data was obtained from Nepal Demographic and Health Survey (NDHS) 2016-17. Age-appropriate coverage of Bacillus Calmette-Guerin vaccine (BCG), oral polio vaccine (OPV) doses 1-3, pentavalent vaccine (PE) doses 1-3, and first dose of measles, mumps, and rubella vaccine (MMR) were estimated using Kaplan Meier method. Multilevel logistic regression with random intercept was used to identify the factors associated with age-appropriate vaccination.ResultsThe crude coverage of the vaccines included in the study ranged from 91.5% (95% CI, 88.5-93.7) for PE3 to 97.8% (95.8-98.7) for BCG. Although the crude coverage of all the vaccines was above 90%, the age-appropriate coverage was significantly low, ranging from 41.5% (36.5-46.6) for PE3 to 73.9% (69.2-78.1) for PE1. Furthermore, high disparity in timely vaccination coverage was observed at regional level. Compared to the age-appropriate vaccination coverage in other provinces, Province 2 had the lowest coverage of all, followed by that in Province 6. The timeliness of vaccination was significantly associated with subnational regions i.e., provinces and the season of childbirth.ConclusionAlthough the immunization program in Nepal has achieved the target of 90% crude coverage of all the childhood vaccines, the age-appropriate coverage is significantly low which undermines the effectiveness of the vaccines administered. Thus, along with crude coverage, timeliness of the vaccines administered should be taken into consideration and thoroughly monitored at national and subnational levels. Provincial government should formulate tailored strategies to ensure the timely administration of the childhood vaccines.

Project description:ObjectiveTo estimate the coverage and factors associated with full immunisation coverage among children aged 12-59 months in Bangladesh.Study designThe study is cross sectional in design. Secondary dataset from Bangladesh Demographic and Health Survey was used for this analysis. Immunisation status was categorised as 'fully immunised' if the children had received all the eight recommended vaccine doses otherwise 'partially/unimmunised'.SettingsBangladesh.ParticipantChildren aged 12-59 months were the study participants. Participants were randomly selected through a two-stage stratified sampling design. A total of 6230 children were eligible for the analysis.ResultsAbout 86% of the children (5356 out of 6230) were fully immunised. BCG has the highest coverage rate (97.1%) followed by oral polio vaccine 1 (97%) and pentavalent 1 (96.6%), where the coverage rate was the lowest for measles vaccine (88%). Coverage was higher in urban areas (88.5%) when compared with rural ones (85.1%). Full immunisation coverage was significantly higher among children who lived in the Rangpur division (adjusted OR (AOR)=3.46; 95% CI 2.45 to 4.88, p<0.001), were 48-59 months old (AOR=1.32; 95% CI 1.06 to 1.64, p=0.013), lived in a medium size family (AOR=1.56; 95% CI 1.32 to 1.86, p<0.001), had parents with a higher level of education (AOR=1.96; 95% CI 1.21 to 3.17, p=0.006 and AOR=1.55; 95% CI 1.05 to 2.29, p=0.026) and belonged to the richest families (AOR=2.2; 95% CI 1.5 to 3.21, p<0.001). The likelihood of being partially or unimmunised was higher among children who had the father as their sole healthcare decision-maker (AOR=0.69; 95% CI 0.51 to 0.92, p<0.012).ConclusionsThere were significant variations of child immunisation coverage across socioeconomic and demographic factors. These findings will inform innovative approaches for immunisation programmes, and the introduction of relevant policies, including regular monitoring and evaluation of immunisation coverage-particularly for low-performing regions, so that the broader benefit of immunisation programmes can be achieved in all strata of the society.

Project description:BackgroundIntestinal parasitic infections are the world's largest public health issue, primarily in developing nations. The World Health Organization (WHO) recommends deworming as a preventative or therapeutic measure for all vulnerable people residing in endemic areas. Despite this issue, there is little data on the prevalence and associated factors of deworming drug use among children under five years of age in East Africa.ObjectiveThis study aimed to evaluate the prevalence and contributing factors of deworming coverage among children under the age of five in East Africa using the most available national health survey data.MethodsData from the Demographic and Health Survey, which included 103,865 weighted children between the ages of 12-59 months, were used in this investigation. Our outcome of interest was taking deworming medicine six months before the interview. A logistic regression model was then fitted. A cutoff P value of 0.2 was used in the binary logistic regression analysis. To identify significant variables, a 95% confidence interval and adjusted odds ratio (AOR) with a value < 0.05 were used.ResultsThe prevalence of deworming in East Africa was 54.13% (95% CI: 53.83%-54.43%). The maternal age group of 24-34 years, and from 35-49 years (AOR = 1.37, 95% CI, 1.32,1.42), and (AOR = 1.71, 95% CI, 1.62,1.79), employed women (AOR = 1.62, 95% CI, 1.58,1.67), being from rural(AOR = 1.11,95% CI,1.07,1.15), unmarried mothers (AOR = 1.12,95% CI,1.09,1.15), mothers from poorer, middle, richer, and richest households (AOR = 1.16,95% CI, 1.12,1.21), (AOR = 1.23, 95% CI, 1.18,1.28), (AOR = 1.22,95% CI, 1.16,1.27), and (AOR = 1.27, 95% CI, 1.21,1.34) having at least one antenatal care follow up(AOR = 2.90, 95% CI, 2.63,3.16), health facility delivery(AOR = 1.69, 95% CI,1.64,1.75), mass media exposure AOR = 1.32, 955 CI, 1.29,1.36), having of 3-5 children (AOR = 0.89, 95% CI, 0.86,0.93), more than five children (AOR = 0.79, 95% CI, 0.73,0.86), and parity of 2nd or 3rd birth order (AOR = 1.05, 95% CI, 1.01,1.09) as compared to primi mothers were associated with the deworming among under five children in east Africa respectively.ConclusionThe under-five population in East Africa had a lower prevalence of deworming medication per the most recent DHS findings. Promoting mother and child health services (antenatal care, institutional delivery, family planning), as well as women's empowerment, should be prioritized.

Project description:BackgroundThere are few estimates of vaccination-averted influenza-associated illnesses in China.MethodsWe used a mathematical model and Monte Carlo algorithm to estimate numbers and 95% confidence intervals (CI) of influenza-associated outcomes (hospitalization, illness, and medically-attended (MA) illness) averted by vaccination among children aged 6-59 months in Suzhou from October 2011-September 2016. Influenza illnesses included non-hospitalized MA influenza illnesses and non-MA influenza illnesses. The numbers of influenza-associated outcomes averted by vaccination were the difference between the expected burden if there were no vaccination given and the observed burden with vaccination. The model incorporated the disease burden estimated based on surveillance data from Suzhou University Affiliated Children's Hospital (SCH) and data from health utilization surveys conducted in the catchment area of SCH, age-specific estimates of influenza vaccination coverage in Suzhou from the Expanded Program on Immunization database, and influenza vaccine effectiveness estimates from previous publications. Averted influenza estimations were presented as absolute numbers and in terms of the prevented fraction (PF). A hypothetical scenario with 50% coverage (but identical vaccine effectiveness) over the study period was also modeled.ResultsIn ~250,000 children, influenza vaccination prevented an estimated 731 (CI: 549-960) influenza hospitalizations (PF: 6.2% of expected, CI: 5.8-6.6%) and 10,024 (7593-12,937) influenza illnesses (PF: 6.5%, 6.4-6.7%), of which 8342 (6338-10,768) were MA (PF: 6.6%, 6.4-6.7%) from 2011 to 2016. The PFs declined each year along with decreasing influenza vaccination coverage. If 50% of the study population had been vaccinated over time, the estimated numbers of averted cases during the study period would have been 4059 (3120-5762) influenza hospitalizations (PF: 27.2%, 26.4-27.9%) and 56,215 (42,925-78,849) influenza illnesses (PF: 28.5%, 28.3-28.7%), of which 46,596 (35,662-65,234) would be MA (PF: 28.5%, 28.3-28.7%).ConclusionInfluenza vaccination is estimated to have averted influenza-associated illness outcomes even with low coverage in children aged 6-59 months in Suzhou. Increasing influenza vaccination coverage in this population could further reduce illnesses and hospitalizations.
