Suspension of social vaccination of COVID-19 vaccine in Guangzhou, strengthening flow adjustment and cutting off the transmission chain have become the primary task.

CCTV News:The Guangdong Provincial Health and Health Commission reported today (June 1) that there were 11 new confirmed cases in Guangdong on May 31, of which 1 case was diagnosed as asymptomatic infection, all of which were reported in Guangzhou. Two new cases of asymptomatic local infection were reported in Guangzhou. Since yesterday, Guangzhou has adjusted the pace of vaccination, first arranging group appointments and collective vaccinations for key industries and key groups in an orderly manner, suspending individual appointments and social vaccination for COVID-19 vaccines.

Dawn, Vice Mayor of Guangzhou:Recently, the general public’s willingness to vaccinate is high, and the inoculation points are overcrowded. In order to reduce the possible risk of Covid-19 infection, we temporarily stop social vaccination. Please rest assured! We will restart personal appointment vaccination and on-site vaccination as soon as possible according to the prevention and control situation.

The first task: strengthen the flow and trace the source and cut off the communication chain.

Li Ming, deputy mayor of Guangzhou, said that the virus gene sequencing of all the infected people in this epidemic is highly homologous, and all the infected people are mutant strains found in India. This virus has the characteristics of short incubation period, fast transmission speed and high virus load. Therefore, Guangzhou strengthened community prevention and control, and suspended social vaccination of COVID-19 vaccine. But will this affect the progress of establishing an immune barrier? Let’s listen to the experts.

Wu Hao, expert of Guangdong Working Group of the State Council Joint Prevention and Control Mechanism Comprehensive Group:Why stop the vaccination of some vaccines and concentrate on nucleic acid detection and screening is to strive for early detection. Vaccination is to produce antibodies, which may take some time. For the prevention and control of this epidemic, the role of vaccines is not particularly great. Generally speaking, the epidemic can be controlled within 28 days, that is, within two incubation periods. This is the first point. Second, generally speaking, vaccination in risk areas, especially social vaccination, may lead to the gathering of people and the possibility of unnecessary cross-infection. Therefore, the suspension of vaccination in some areas is also to avoid crowd gathering. Third, the primary task at present is to prevent and control the epidemic situation and cut off the community transmission chain. It is scientific to concentrate all efforts to control the source of infection and cut off the transmission route, and to suspend the adjustment of vaccination work.

As we all know, Guangzhou is a first-tier city, and we can’t completely stop the city, but for the "core area" of the epidemic, it is required to stop the area and reduce the possibility of cross-infection. Therefore, the core area and sub-core area are adopted to find the most appropriate balance between life production and epidemic prevention and control.
