Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital: At present, the prevalence of Omicron Virus strains in my country is generally high in asymptomatic infections and mild cases. The reduced virulence of the Omicron strain is relative to the previous strains. At present, it is still more harmful than influenza, especially for the elderly who have not been vaccinated or have not been fully vaccinated.
Wang Guiqiang said that data from the Hong Kong Special Administrative Region shows that there are currently more than 1.1 million infected people in Hong Kong and more than 8,000 deaths, with a case fatality rate of 0.7%, which is much higher than that of influenza. In addition, the Hong Kong epidemic data gives us a very important reminder that vaccination is closely related to the case fatality rate. From the data in Hong Kong, the case fatality rate of the unvaccinated is 3.2%, the case fatality rate of one injection is 0.96%, and the case fatality rate of two injections is 0.96%. The case fatality rate is 0.14%, and the case fatality rate of three injections is 0.03%.
From this data, three doses of vaccination can effectively reduce the fatality rate after Omicron infection. (China News Network)
