Measles immunization coverage and dropout rate on children between 6 months and 14 years in the City of Tshwane, Hammanskraal

Abstract

Measles is a highly contagious virus that can affect the entire population if an effective immunisation programme is not in place. This study was aimed at determining the measles immunisation coverage and the dropout rate among children aged between 6 months and 14 years and at assessing factors associated with caregivers’ knowledge and perception of, and attitude towards the measles immunisation programme. Between 14 May 2018 and 31 July 2018, a descriptive, cross-sectional study design was conducted using simple random sampling to sample 381 caregivers of children at nine public health facilities at Tshwane Sub-district 2, Hammanskraal town. Data were collected by means of a structured questionnaire and observational checklist, and analysed using IBM SPSS version 23.0. Overall, the measles immunization coverage was 95.8% (365/381) and the MCV1-MCV2 dropout rate was 4.1%. The association between educational level and employment status (correlation coefficient=0.157**, p=0.0002), measles knowledge (correlation coefficient=-0.244**, p=0.000), immunization importance (correlation coefficient=-0.194**, p=0.000) and measles vaccine schedule (correlation coefficient=-0.138**, p=0.007) were found to be significant at p<0.05. The findings in this study revealed that caregivers’ positive attitude towards, and knowledge of measles immunisation programme resulted in high measles immunisation coverage and low dropout rate. It is recommended that continuous positive immunisation education about the benefits and importance be emphasized in order to increase immunisation uptake.
