ABSTRACT

The Chinese Center for Disease Control and Prevention (China CDC) has suggested that more than 1 billion people need to be vaccinated against COVID-19 to establish an effective immune barrier in China. According to the National Health Commission of the People's Republic of China 's website (National Health Commission, PRC), until 14 March 2022, the total number of COVID-19 vaccines in China had reached 122,537 million, and 1,239,171,000 people had been vaccinated with the coronavirus vaccine. Although the status of COVID-19 vaccination has met the requirements of an effective immune barrier, building the effective immune parclose still needs to be considered because of the characteristics of solid transmission, high viral load and high pathogenicity of Delta and Omicron strains, and continuous vaccination is still needed to cope with the virus mutation. Based on the expectation confirmation theory and risk perception, our study accurately evaluates the evolution of public risk perception and the influencing factors of public behavioral decisions on continuous vaccination under the post-epidemic situation, which is of great significance for the government to promote COVID-19 vaccination effectively.
