Husbands’ Support Synergistically with Distance to Vaccination Centre Associated with Childhood Immunization Compliance During the COVID-19 Pandemic in Indonesia

Introduction: During the COVID-19 pandemic, compliance with childhood immunization in Indonesia declined. Objective: To determine the independent factors and the relation between the synergistic effect of husbands’ support and distance to vaccination centres on compliance with childhood immunization during the pandemic. Material and Methods: A total of 506 mothers in Jambi Province, Indonesia, participated in a crosssectional study from March until May 2021. The associations between the factors were analysed using logistic regression. From the most contributing variables, the researchers made dummy variables (2x2) to investigate the synergistic association on compliance with childhood immunization of husband support and the distance to vaccination centres. Results: Among the variables with positive correlations to childhood vaccination, supportive husbands and less distance to vaccination centres had a synergistic effect on compliance with immunization (AOR 95% CI = 4.10 [2–8.41]). Groups that was less supportive from husband and the distance <4km as well as the groups was husband’s support but the distance?>4km had less compliance (AOR 95% CI = 2.47 [1.22–4.97]; 2.83 [1.18–6.81]). Conclusions: Family support and accessibility to childhood immunization should be increased during vaccination campaigns.
