On October 14, 2021, Nature published a news commentary, pointing out that the Chinese-made new crown vaccine has played a vital role in the global epidemic, but it also faces doubts about the protection time.

A total of about 7.3 billion doses of the new crown vaccine have been vaccinated globally, of which China's new crown vaccine accounts for about half, the most important being Beijing Kexing and Sinopharm Zhongsheng, who received 1.8 billion doses and 1.5 billion doses respectively.

China's domestic vaccination volume exceeds 2.2 billion doses. At the same time, more than 1 billion doses of China's new crown vaccine have been vaccinated in 110 other countries, including Indonesia, Brazil, Pakistan, Turkey, Iran, Philippines, Morocco, Thailand, Argentina, Venezuela, Cambodia, Sri Lanka , Chile, Mexico, Bangladesh, etc.

Summarize

The covid-19 virus is a huge disaster. There are currently 239 million confirmed cases worldwide and 4.87 million deaths. The research and development of vaccines and new drugs has made a huge contribution to epidemic control. Vaccines have controlled the infection rate. Small molecule drugs such as neutralizing antibodies and Merck's Molnupiravir have prevented most of the transition from mild to severe, and greatly reduced the mortality rate.
