Developing an effective and sustainable national immunisation programme in China: issues and challenges.

Since its establishment in 1978, China's National Immunization Program has made remarkable achievements in the control of vaccine-preventable diseases. The National Immunization Program is a vertically integrated programme in the health system, which delivers immunisation services to children. However, achieving the ambitious goals of the Immunization Agenda 2030 and Healthy China 2030 will require overcoming challenges to the National Immunization Program's future expansion and development. Key challenges include inclusion of all WHO-recommended vaccines into the routine programme, improving the function and support of the National Immunization Advisory Committee, increasing and sustaining reliable vaccination financing, ensuring uninterrupted vaccine supplies, overcoming regional disparities in immunisation practices and cold chain processes, strengthening the workforce, and integrating immunisation information systems into all aspects of the programme. It is crucially important to strengthen the National Immunization Program to attain universal coverage of life-saving vaccines in China and meet the 2030 goals.
