Innovation Lab for Vaccine Delivery Research

The Innovative Lab for Vaccine Delivery Research (VaxLab) was founded in 2021 with strategic support from the Bill & Melinda Gates Foundation. Chaired by Professor Shenglan Tang, VaxLab aims to provide new evidence for the development of the National Immunization Program in China and scale up the use of WHO-recommended vaccines. In 2023, VaxLab concluded three projects with seven articles published in peer-reviewed journals. Four projects are ongoing. In September 2023, VaxLab received an additional investment of over 1.6 million U.S. dollars from the Bill & Melinda Gates Foundation and subsequently initiated new projects, covering topics on optimizing financing for key non-NIP vaccines, using the pay-it-forward strategy to promote HPV vaccine uptake, maternal vaccines, and vaccine equity, etc.

In addition to conducting research projects, the VaxLab team proactively initiated policy advocacy and communication campaigns. As of December 6th, 2023, the VaxLab released eight policy briefs in total and organized six workshops featured by domestic and internationally renowned experts and one media-PI workshop. In total, 31 news articles featuring VaxLab’s research findings and policy briefs were published through collaboration with the Caixin, Yicai, People’s Daily Health APP, Southern Weekly, BJNews, Southern Metropolitan, etc.

SUB-PROJECT | Gender Factors in Non-Immunization Program Vaccine Administration Amid Changing Maternity Policies

Led by Professor Qian Long and Professor Yu Wang, the sub-project of VaxLab aims to investigate the prevalence of preference of caregivers for several non-NIP vaccines for infants in Chongqing, China, and explore health system and social determinants that impact accessibility, availability, acceptability, and affordability of non-NIP vaccines. The research team invited mothers of infants aged two months in one downtown and one suburban district in Chongqing and completed the baseline study between December of 2023 and January of 2024. The evidence generated from this study will inform decision-making to enhance equity in access to non-NIP vaccines, particularly in less developed areas of China.

SUB-PROJECT | The Vaccination Rate and Influencing Factors of Non-NIP Vaccines in Remote Areas of China

Led by Professor Chenkai Wu, the sub-project of VaxLab aims to provide a scoping review to investigate vaccination coverage, uptake rates, barriers, facilitators, accessibility, and challenges among vulnerable, disadvantaged, and marginalized individuals and communities in China. A subsidiary study within an existing longitudinal cohort project will be part of the project and assess the vaccination rates of selected non-National Immunization Program (NIP) vaccines recommended by the World Health Organization in West China.
