Currently, China’s new crown vaccination policy is that all new crown vaccinations are free for Chinese citizens, and the price of foreign new crown vaccines usually ranges from one hundred to several hundred yuan. Starting from 2021, China’s new crown vaccination policy is that all Chinese citizens will receive the new crown vaccine free of charge, without charging for the vaccine and without charging for the injection. Foreign countries have not realized the free vaccination, usually due to the vaccine manufacturer and technology varies slightly, usually equivalent to RMB 100 yuan to several hundred dollars. After vaccination, the vaccine usually produces antibodies specific to the New Crown virus in the body, which protects the human body from being infected by the New Crown virus. China’s free vaccination policy for the New Crown vaccine can improve the immunity of the overall population, which is of positive significance for the prevention and control of the New Crown epidemic in China.
