At a summit on indoor air purification held in Guangzhou recently, Academician Zhong Nanshan delivered a speech. He mentioned that all 13 seriously ill patients of COVID-19 in Guangzhou did not get the vaccine, which shows the importance of vaccination.
"Director of Fudan university in Shanghai huashan hospital infection Wen-hong Zhang also mentioned a set of data recently, British and Israeli vaccination rates are close to 70%, and the case fatality rate from 18% last year, the highest peak, down to the nearest 0.1%, the protection of the vaccine effect is very obvious."
Recently, the guangzhou Center for Disease Control and Prevention, Sun Yat-sen University, the State Key Laboratory of Respiratory Diseases and other multi-unit joint research team analyzed the data of the protective effect of COVID-19 vaccine during the local epidemic in Guangzhou this year. The results showed that the domestic vaccine was 100% effective in protecting against severe disease caused by the Delta mutant strain.
That is to say, after vaccination, no case of severe disease; In addition, the Chinese vaccine also had a good protective effect on moderate, mild and asymptomatic infected persons. This set of real data strongly suggests that the vaccines we currently use are effective.
