The effectiveness of pay-it-forward in addressing HPV vaccine delay and increasing uptake among 15–18-year-old adolescent girls compared to user-paid vaccination: a study protocol for a two-arm randomized controlled trial in China

This review, conducted by Innovation Lab for Vaccine Delivery Research (VaxLab) from Duke Kunshan University, was published in Vaccine. The study systematically compares the status of new vaccine introduction within national immunization programs across 13 countries in Southeast and South Asia, with a particular focus on differences associated with Gavi funding eligibility. The findings show that countries eligible for Gavi’s middle-income country (MIC) support approach lag behind in introducing key vaccines such as pneumococcal conjugate vaccine (PCV), human papillomavirus (HPV) vaccine, and rotavirus vaccine. Major barriers include underdeveloped evidence-based decision-making processes, limited domestic financing, high vaccine prices, and gaps in immunization system readiness. This article highlights the need to strengthen governance and sustainable financing mechanisms, optimize resource use, and leverage targeted technical support from global partners to accelerate equitable access to life-saving vaccines and advance the Immunization Agenda 2030.

This study, jointly conducted by Prof. Hong Jiang’s team from Fudan University and the Shanghai Municipal Center for Disease Control and Prevention, was published in the Journal of Clinical Pediatrics. Using data from the Shanghai Birth Medical Information System (2012–2022), the researchers analyzed trends and determinants of influenza vaccination among pregnant women and its association with preterm birth.The Study found that multiple sociodemographic factors are significantly associated with influenza vaccination behavior among pregnant women in Shanghai between 2012 and 2022, and influenza vaccination during pregnancy may be related to a reduced risk of preterm birth. It is recommended to further strengthen public education and service support, continuously promote vaccination efforts, and effectively safeguard maternal and infant health.
