ABSTRACT
Vaccines for immunization programs play a pivotal role in the prevention and control of infectious diseases in China. Since the implementation of the Expanded Program on Immunization in 2007, a total of 15 vaccines have been used in the national immunization program, which can prevent 15 kinds of diseases. The development of vaccines in China's immunization program in the past decade is analyzed in terms of variety, quantity, production enterprise, quality standard, and supervision system. The results show that the average dose of vaccines for China's immunization planning is about 570 million doses per year from 2011 to 2020. The overall development of the vaccine industry for immunization planning is stable, and there are between one to five manufacturers for each type of vaccine mainly relying on domestic production. Vaccine quality standards have been continuously improved and are basically consistent with international standards. The vaccine supervision system has been continuously completed and covered the entire process of research and development, production and distribution.
