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. Hong Jiang and her team from Fudan University in collaboration with Prof. Yanran Yang from Duke Kunshan University, and published in BMC Public Health, aimed to develop the Maternal Influenza Vaccine Hesitancy Scale based on the 5Cs vaccination hesitancy scale, containing the subscales of confidence, complacency, constraints, calculative, and collective responsibility. The study also provides a preliminary overview of the current hesitancy on maternal influenza vaccination in China.

This research conducted by Prof. Jing Li and team from Sichuan University, was published in Cancer Prevention Research. It presents a pilot randomized controlled trial evaluating the feasibility and acceptability of a pay-it-forward strategy to boost HPV vaccination among 15–18-year-old girls in China. Conducted in a community health center in western China, the study found a significantly higher uptake in the intervention group (98% vs. 82%), with strong participant support for the approach. The findings offer practical evidence for innovative strategies to improve vaccine uptake among adolescents.

This research, conducted by Prof. Dan Wu from Nanjing Medical University and collaborators, was published in BMC Global and Public Health and focuses on the feasibility of the pay-it-forward strategy in increasing vaccine uptake.The commentary highlights that the pay-it-forward approach demonstrates scalability and cross-cultural adaptability, with the potential to be integrated with digital tools and government immunisation programs to promote equitable vaccine access and advance the goal of universal health coverage.
