To understand the status of rotavirus vaccination among children born in Beijing from December 2010 to January 2017, and to analyze the factors affecting rotavirus vaccination.

Six hospitals in six districts of Beijing were selected. The general information of the first 30 patients of the month, who were aged from 2 months to 5 years old, visited hospital for the first time and diagnosed as infectious diarrhea, were collected. The information of rotavirus vaccination was confirmed with the Children Vaccination Information Management System. Vaccination rates and inoculation time of rotavirus vaccine (LLR strain) were compared and analyzed. Unconditional logistic regression was used to analysis the factors influencing rotavirus vaccination.

A total of 2 078 children were enrolled in this study. Three hundred and eight subjects (14.8%) received one dose of vaccine, 76 (3.7%) received two doses, and 11 (0.5%) received three doses. Using the children born from February 2016 to January 2017 as control, children born from December 2010 to January 2014 had the highest vaccination rate (OR=1.972; 95%CI: 1.361-2.858) and the highest rate of first-dose vaccination within 12 months after birth (OR=6.478; 95%CI: 3.050-13.762). The rotavirus vaccination rate (x²=30.300, P<0.01) and the vaccination rate of the first-dose vaccination within 12 months after birth (x²=32.439, P<0.01) decreased gradually along with time of birth goes by.

The vaccination rate of rotavirus vaccine in Beijing has decreased since 2010. The vaccination rate and inoculation time were closely related to the location of the children. Health education should be strengthened to improve the awareness of disease prevention. Meanwhile, standardized management of vaccination clinics for the promotion of class-two vaccines as well as the quality of vaccination services should be improved.
