The community transmission chain of Yingkou epidemic has been basically blocked, and the transmission chain is relatively clear. Of the 970,000 tourists who recently met with Bayuquan District, about 1.4 million came from Dalian. The vaccination rate in Dalian reached about 70%, which played a role in blocking the spread of vaccines and had obvious protective effect. 6.5438+0.02 million people in Shenyang were tested for nucleic acid, and all the results were negative. Anshan City and Panjin City, which are adjacent to Yingkou City, were not found to be positive in the screening of dangerous personnel. The main function of novel coronavirus vaccine is to stimulate the body to produce protective antibodies and prevent novel coronavirus infection.
Novel coronavirus is an acute infectious disease caused by novel coronavirus infection. The outbreak of epidemic worldwide has caused tens of millions of infections and millions of deaths, causing extremely serious harm. All parties are actively carrying out epidemic prevention and control work. However, the epidemic situation in some countries and regions is still very serious. Novel coronavirus is a highly contagious disease. It is necessary to prevent and control the spread of droplets through the respiratory tract in time. When sneezing or coughing, you can cover your nose and mouth with clean paper towels to avoid the spread of droplets, keep regular work and rest, go to bed early and get up early, and keep indoor ventilation.
The drug resistance effect is good, and the successful development of the vaccine will not bring great side effects to the human body, and only a few people will have obvious adverse reactions. The vaccine has not been officially marketed, but it has entered the third clinical trial stage. If the test is successful, it will be officially launched and widely used. China is accelerating vaccination in COVID-19 in key areas, key populations and key cities. If China wants to establish an immune barrier, it may need more than 654.38 billion people to be vaccinated with new vaccines. The higher the vaccination rate, the stronger the immune barrier. We still have a long way to go. The research and development of vaccines in novel coronavirus must be carried out before and after marketing, which is the guarantee of vaccine safety.
