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 vacci-nation were collected through questionnaire interview. Logistic regression was used to analyze factors influen-cing immunization status by using SPSS22.0. Results Among the 863 participating children, the immuni-zation 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 par-ents 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.
ABSTRACT
Objective To investigate the immunization status of the left-behind/non-left-behind children in the rural areas of Zhejiang Province. Methods Multi-stage cluster random sampling was adopted to recruit 0-6 years old children and their guardians in a rural mountainous county in Lishui District of Zhejiang Province. Household survey was conducted using structured questionnaires. Records of vaccination were obtained and verified in the local disease control and prevention center. Results A total of 420 questionnaires were issued, with a number of 416 were complete and valid. The Valid responsive rate was 99.05% . Among them, 97 were left-behind and 319 were non-left-behind children. The immunization coverage rates did not differ significantly between the left-behind and non-left-behind children. The timely immunization rates of the third shot of hepatitis B vaccine and the first shot of encephalitis vaccine differed significantly between left-and non left-behind children (P=0.049 and P=0.044, respectively) . Conclusion Immunization status of the left-behind children in the rural areas of Zhejiang province was in a good condition in general. The local disease control and prevention center should strengthen the communication, to promote immunization knowledge and to improve family supervision of the left-behind children.
