Individual-, family- and community-level determinants of full vaccination coverage among children aged 12-23 months in western Kenya
ABSTRACT To identify individual-, family-, and community-level determinants of full vaccination status at most challenging areas in Kenya, we conducted a cross-sectional study among children aged 12-23 months and their mothers. 1965 children were involved in this research and their mothers completed a questionnaire. Middle or high knowledge of vaccination schedule (Adjusted Odds Ratio (AOR)=2.69, 95%CI: 2.01-3.60 or AOR=8.12, 95%CI:5.50-11.97), medium/long birth interval or first birth (AOR=2.46, 95%CI: 1.29-4.69 or AOR=1.84, 95%CI:1.10-3.09 or AOR=2.14, 95%CI: 1.20-3.84), less than 5 children under five years old (AOR=1.39, 95%CI: 1.04-1.88) and highest community health worker's (CHWs) performance (AOR=2.20, 95%CI: 1.39-3.47) were significantly associated with complete vaccination status in the final multiple regression model. In addition, a interaction between literacy and wealth was significantly related in full vaccination status (AOR=1.38, 95%CI: 1.08-1.75). Increased frequency and quality of CHW visits could be effective intervention to enhance vaccination coverage. Future interventions focusing on vaccination coverage should be given more attention especially to high risk group identified in this study.

ABSTRACT: Parents' knowledge about immunization is an important predictor factor for their children's immunization status. The aims of this study were to assess parents' knowledge and to evaluate the effect of a short educational intervention on improving parents' knowledge of childhood immunization.BMC Pediatrics 10/2014; 14(1):254.

ABSTRACT: Immunization is an important and cost-effective public health intervention to protect the population from illness. In Poland, in addition to free of charge vaccines, listed in the national program on immunization, self-paid vaccinations for pneumococcal, meningococcal, rotavirus, varicella, influenza infections and combination vaccines are recommended. The study objective was to measure the coverage and influencing determinants of self-paid vaccinations in 0-5-year-old children seen between June 2009 and January 2010 at 3 randomly selected GP practices located in one region in the south-western part of Poland. Parents of the children who were seen consecutively were invited to participate and complete questionnaires on socio-demographic data and other factors related to paid vaccination. The response rate: 93.3%. Among the 308 parents (18-50 years old, median 31 years) who agreed to participate, 77.9% (95%CI: 73.0-82.2%) had their child vaccinated with at least one paid vaccine. Combination vaccines were most commonly chosen (62.3%), followed by a pneumococcal (36.4%), influenza (14.7%), meningococcal (13.3%), and rotavirus (12.7%) vaccine. Most parents admitted that their decision was based on a healthcare worker's initiative informing them about the topic. The multi-variable regression model revealed that parent's factors: age≥25 years, high socio-economic status, having one child, and health system factor, i.e. practice location were each associated with greater odds of child immunization The high cost of a vaccine was associated with more than five times lower chance to immunize a child. Observed high coverage rate regarding self-paid vaccines among young children was influenced mostly by combination vaccines. As the cost of a vaccine was an important barrier for the immunization, the gradual introduction of some of currently self-paid vaccines in a national program would be of value. Future interventions on self-paid vaccination coverage should be more tailored, focusing especially on young parents with low income who have more than one child.Vaccine 10/2013; 31(48).

ABSTRACT: This study assesses full and timely vaccination coverage and factors associated with full vaccination in children ages 12-23 months in Gem, Nyanza Province, Kenya in 2003. A simple random sample of 1,769 households was selected, and guardians were invited to bring children under 5 years of age to participate in a survey. Full vaccination coverage was 31.1% among 244 children. Only 2.2% received all vaccinations in the target month for each vaccination. In multivariate logistic regression, children of mothers of higher parity (odds ratio [OR] = 0.27, 95% confidence interval [95% CI] = 0.13-0.65, P ≤ 0.01), children of mothers with lower maternal education (OR = 0.35, 95% CI = 0.13-0.97, P ≤ 0.05), or children in households with the spouse absent versus present (OR = 0.40, 95% CI = 0.17-0.91, P ≤ 0.05) were less likely to be fully vaccinated. These data serve as a baseline from which changes in vaccination coverage will be measured as interventions to improve vaccination timeliness are introduced.The American journal of tropical medicine and hygiene 12/2013; 90(2).
