At the beginning of the founding of New China, the government implemented a series of health policies and measures to quickly improve the people's health. The development of vaccine and the construction of public health facilities work together to provide important support for the implementation of the ??prevention first'' policy, and have played an important role in preventing the spread of various infectious diseases. Since the outbreak of COVID-19, China has rapidly deployed five technical routes to accelerate vaccine research and development. Combining vaccination with public health emergency measures, Chinese government stopped the spread of COVID-19 scientifically and effectively. Due to the rebounded global epidemic, the pressure of ??external defense input, internal defense rebound'' keeps increasing. How to adjust the strategies for epidemic prevention and control has become an important issue. This article reviews the vaccine research and development, vaccine administration, dynamic adjustment of immunization strategies, booster immunization, immunization for the elderly, and the immunization plan. With predicting the trend of global epidemic and analyzing China's COVID-19 vaccination strategy, it provides new thoughts for the next strategic adjustment of China's COVID-19 vaccination as well as the epidemic prevention and control.

Key words: COVID-19, vaccine, booster immunization, the elderly, immunization program, immunization strategy
