Determinants of Defaulting from Completion of the Second Dose of Measles Among 18 to 24 Month-Old Children in Gindeberet District, West Shoa, Ethiopia, 2022: An Implication for Action

A second dose of measles (MCV2) was established to immunize children who did not respond protectively to the first dose. However, outbreaks continue to occur despite the availability of safe and effective vaccinations. The objective of this study was to identify determinants of defaulting from completion of the second dose of measles among 18 to 24 month-old children in Gindeberet district, West Shoa, Oromia, from January 6 to March 5, 2022. A community-based, unmatched case-control study was conducted among 654 children (218 cases and 436 controls). A systematic sampling technique was used to select the study participants. Data were collected using a pretested and structured questionnaire. An adjusted odds ratio with a 95% CI and a p -value of <.05 was used to identify the determinants of defaulting from MCV2. Absence of reminder (PNC; AOR = 4.28, 95% CI: 2.34–7.82), Antenatal Care (ANC) contact ≥2 2 (AOR = 5.15, 95% CI: 2.86–9.25), long waiting time (AOR = 2.27, 95% CI: 1.18–4.36), no awareness (AOR = 7.95, 95% CI: 4.21–15.02), not receiving Penta3 (AOR = 4.08, 95% CI: 1.88–8.82), and not receiving ≥2 doses of vitamin “A” (AOR = 4.18, 95% CI: 2.15–8.10) were found to be determinants of defaulting from MCV2. Absence of reminder, ANC ≤2, long waiting time, no awareness, not receiving penta3, and not receiving ≥2 doses of vitamin “A” were determinants of defaulting from MCV2. Hence, mothers should be aware of the importance of a second dose of measles.
