Core Viewpoint - The article emphasizes the urgent need for increased COVID-19 vaccination rates in China, which currently stands at only around 9%. It highlights the importance of vaccination in the context of economic reopening and the challenges posed by virus mutations [1][2][4]. Vaccination Status and Challenges - The vaccination rate in China is notably low at approximately 9%, attributed to public perception of safety and concerns over side effects. This poses a risk as the country prepares for economic reopening [2][4]. - The global vaccination effort is ongoing, with the U.S. leading in total doses administered, followed by China. However, when considering doses per 100 people, countries like Israel and the UAE rank higher [4]. - The effectiveness of Chinese vaccines, such as Sinovac, is highlighted, with a 100% prevention rate for severe cases and hospitalizations, despite varying efficacy rates in preventing infections across different countries [5][4]. Virus Mutation and Its Impact - Virus mutations present significant challenges to vaccine effectiveness and antibody treatments. The duration of vaccine efficacy remains uncertain due to ongoing mutations [5][10]. - Current research indicates that some monoclonal antibodies may lose effectiveness against certain virus strains, necessitating global cooperation to address these challenges [10].
