Immunization coverage of oral live attenuated rotavirus vaccines and its influencing factors among children under 5 years old in Jinshan District of Shanghai

Abstract

Objective To investigate the immunization coverage of oral live attenuated rotavirus vaccines and its influencing factors among children under 5 years old in Jinshan District of Shanghai in order to provide references for optimizing vaccination management in this area. Methods A cross-sectional study was conducted in 6 community vaccination clinics randomly selected from 12 vaccination clinics in Jinshan District. In each selected clinic, 145 children under 5 years old were continuously recruited. Information on immunization status, demographics of children, family socioeconomic status and parents′ knowledge of vaccination were collected through questionnaire interview. Logistic regression was used to analyze factors influencing immunization status by using SPSS22.0. Results Among the 863 participating children, the immunization coverage rate of oral live attenuated rotavirus vaccines was 61.07%. Multivariate analysis revealed that children having an urban registration status (OR=2.21), better family income (OR=1.47) and parents with high recognition of rotavirus diarrhea (OR=8.56) and stronger intention to following doctor′s suggestions (OR=1.96) were more likely to accept oral live attenuated rotavirus vaccines, while those from families with a medical professional were less likely to be vaccinated (OR=0.57). Conclusion The immunization coverage rate of oral live attenuated rotavirus vaccines among children in Jinshan District were influenced by various factors such as children′s household registration status, household income, parents′ knowledge regarding vaccination and doctors′suggestions. Health education on immunization should be strengthened and tailor-made to improve the coverage of oral rotavirus vaccination.
