The research was conducted by Xiaohua Ying and team from Fudan University and published in Infectious Diseases of Poverty. This study investigates the vaccination rates and primary obstacles associated with four non-National Immunization Program (NIP) vaccines in China which reveals disparate coverage rates, with the Hib vaccine leading at 54.9-55.9%. The research underscores the urgency of improving the coverage for these vaccines, reducing regional disparities, and suggests a cautious, gradual approach to their inclusion in the national immunization plan, with special attention to high-risk populations and underdeveloped regions.
Independent and joint associations of sex and birth order with non‑national immunization program vaccine coverage among Chinese children: a cross-sectional analysis
This research conducted by Prof. Xiaolin Xu and team from Zhejiang University, was published in the International Journal for Equity in Health. Based on a 2022 survey in Zhejiang and Henan provinces, the study analyzed the independent and joint associations of sex and birth order with non-National Immunization Program (non-NIP) vaccine coverage among Chinese children aged 1–6. The results showed that birth order was an important factor influencing vaccination, with the lowest coverage observed among later-born girls, particularly third or later-born daughters.
