Reliability and validity study of the “5Cs” hesitancy scale for maternal influenza vaccination among pregnant and postpartum women

This research, led by Prof. Jing Li from Sichuan University, in collaboration with Prof. Dan Wu from Nanjing Medical University, was published in PLOS ONE. Based on a randomized controlled trial conducted in Chengdu, China, the study investigated key factors influencing caregivers’ actions to vaccinate adolescent girls against HPV. The results highlighted the significant role of a novel “pay-it-forward” intervention in doubling HPV vaccine uptake. Other factors, including caregivers’ knowledge, intention to delay vaccination, occupational status, and prior vaccine refusal, were also strongly associated with vaccination behavior. Recommendations to promote universal and equitable access to HPV vaccine through targeted health education, financial support and community engagement.

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.

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.
