This paper was published by Hai Fang and team from Pecking University in the JAMA Network Open. This cross-sectional study on 5294 children in China revealed higher coverage rates for National Immunization Program (NIP) vaccines compared to non-NIP vaccines, with notable inequity observed among the latter. Improvements in equitable coverage of non-NIP vaccination may be urgently needed to meet national immunization goals.
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.
