Abstract
Measles vaccination is currently recommended at 9 months, since maternal antibodies are supposed to protect infants until that age. In this study of 6-month-old Malawian infants 98.3% (58/59) had non-protective IgG levels against measles, irrespective of HIV exposure. Anticipating the first dose at 6 months could be considered.

Complete childhood vaccination and associated factors among children aged 12-23 months in Dabat demographic and health survey site, Ethiopia, 2022. BMC Public Health 2023; 23:802. [PMID: 37131146 PMCID: PMC10152426 DOI: 10.1186/s12889-023-15681-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 04/15/2023] [Indexed: 05/04/2023] Open
Abstract
INTRODUCTION Childhood immunization is one of the most cost-effective public health strategies to prevent children's mortality and morbidity from infectious diseases, but the Covid-19 pandemic and associated disruptions have strained health systems, and worldwide 25 million children missing out on vaccination in 2021. Of the 25 million, more than 60% of these children live in 10 countries including Ethiopia. Therefore, this study aimed to assess complete childhood vaccination coverage and associated factors in the Dabat district. METHOD A community-based cross-sectional study was conducted from December 10/2020 to January 10/2021Gregorian Calendar. The data for this study was extracted from information collected for the assessment of maternal, Neonatal, and Child Health and health services utilization in the Dabat demographic and health survey site. Vaccine-related data were collected using an interviewer-administered questionnaire. An adjusted odds ratio with a 95% confidence interval was used to identify the presence and the direction of the association. RESULTS Based on vaccination cards and mothers/caretakers' recall 30.9% (95%CI: 27.9-34.1%) of children aged 12-23 months in the Dabat district were completely immunized. Urban residency [AOR 1.813, 95% CI: (1.143, 2.878)], delivered in the health facility [AOR = 5.925, 95% CI: (3.680, 9.540)], ANC follow-up during their pregnancy [AOR 2.023, 95% CI: (1.352, 3.027)], rich wealth index [AOR = 2.392, 95% CI: (1.296, 4.415)], and parity [AOR 2.737, 95% CI: (1.664, 4.500)] were significantly associated with complete child vaccination. RECOMMENDATION AND CONCLUSION Complete vaccination coverage among children aged 12-23 months in the Dabat district was lower than the Global vaccine plan and Ethiopian ministry of health goal in 2020. Therefore, Health care providers and other stakeholders should mobilize the community to improve mothers' health-seeking behavior toward pregnancy follow-up and health facility delivery to improve childhood vaccination. Besides, expanding the service to remote areas are necessary to increase the immunization access.

Association between childhood immunisation coverage and proximity to health facilities in rural settings: a cross-sectional analysis of Service Provision Assessment 2013-2014 facility data and Demographic and Health Survey 2015-2016 individual data in Malawi. BMJ Open 2022; 12:e061346.

Abstract
OBJECTIVES Despite significant progress in childhood vaccination coverage globally, substantial inequality remains. Remote rural populations are recognised as a priority group for immunisation service equity. We aimed to link facility and individual data to examine the relationship between distance to services and immunisation coverage empirically, specifically using a rural population. DESIGN AND SETTING Retrospective cross-sectional analysis of facility data from the 2013-2014 Malawi Service Provision Assessment and individual data from the 2015-2016 Malawi Demographic and Health Survey, linking children to facilities within a 5 km radius. We examined associations between proximity to health facilities and vaccination receipt via bivariate comparisons and logistic regression models. PARTICIPANTS 2740 children aged 12-23 months living in rural areas. OUTCOME MEASURES Immunisation coverage for the six vaccines included in the Malawi Expanded Programme on Immunization schedule for children under 1 year at time of study, as well as two composite vaccination indicators (receipt of basic vaccines and receipt of all recommended vaccines), zero-dose pentavalent coverage, and pentavalent dropout. FINDINGS 72% (706/977) of facilities offered childhood vaccination services. Among children in rural areas, 61% were proximal to (within 5 km of) a vaccine-providing facility. Proximity to a vaccine-providing health facility was associated with increased likelihood of having received the rotavirus vaccine (93% vs 88%, p=0.004) and measles vaccine (93% vs 89%, p=0.01) in bivariate tests. In adjusted comparisons, how close a child was to a health facility remained meaningfully associated with how likely they were to have received rotavirus vaccine (adjusted OR (AOR) 1.63, 95% CI 1.13 to 2.33) and measles vaccine (AOR 1.62, 95% CI 1.11 to 2.37). CONCLUSION Proximity to health facilities was significantly associated with likelihood of receipt for some, but not all, vaccines. Our findings reiterate the vulnerability of children residing far from static vaccination services; efforts that specifically target remote rural populations living far from health facilities are warranted to ensure equitable vaccination coverage.

Multilevel Analysis of Individual and Contextual Factors Associated with Polio Non-Vaccination in Africa: Further Analyses to Enhance Policy and Opportunity to Save More Lives. Vaccines (Basel) 2021; 9:vaccines9070683. [PMID: 34206156 PMCID: PMC8310107 DOI: 10.3390/vaccines9070683] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 06/10/2021] [Accepted: 06/12/2021] [Indexed: 01/22/2023] Open
Abstract
Background: Africa was certified polio-free in 2020 and to maintain the polio-free status, African countries need to attain and maintain optimal routine polio vaccination coverage. One indicator for optimal polio vaccination coverage is the prevalence of children who have received no polio vaccination through routine services. The objective of the study was to examine the individual-, neighbourhood-, and country-level factors associated with non-vaccination against polio in Africa. Methods: We applied multivariable multilevel logistic regression analyses on recent demographic and health survey data collected from 2010 onwards in Africa. We identified 64,867 children aged 12-23 months (Level 1) nested within 16,283 neighbourhoods (Level 2) from 32 countries (Level 3). Results: The prevalence of non-vaccination for polio ranged from 2.19% in Egypt to 32.74% in Guinea. We found the following factors to be independent predictors of the increased odds of non-vaccination for polio: being a male child, born to mother with no formal education, living in poorer households; being from a polygamous family, living in neighbourhoods with high maternal illiteracy, high unemployment rate, and low access to media. Conclusions: We found that both individual and contextual factors are associated with non-vaccination for Polio.
