The director of the Chinese Health Commission recommended different doses of the vaccine or additional doses to make the vaccine more effective.
The director of the Chinese Center for Disease Control and Prevention (CCCPM) acknowledged that the effectiveness of Chinese vaccines is limited, and the country is considering mixing doses from different laboratories to enhance its effectiveness. “Currently existing vaccines do not have a high protection rate”Gao Fu talked about Chinese vaccines at a meeting held in the western city of Chengdu on April 10 (Saturday). “The official plan is to use different vaccines with different technologies in the immunization process”, He added.
Since Chinese vaccines are used in about 20 countries, and more than 70 countries have reached agreements with Chinese vaccine manufacturers, this move will have a significant impact on a global scale. According to various studies, the efficacy of the most exported Chinese vaccines, namely Sinovac and Sinopharm, is between 50% and 80%. Data collected by the British scientific observation company Airfinity shows that a total of 115 million doses have been exported from China.
Experts elsewhere in the world are considering vaccination in different doses: British researchers are specifically studying the possibility of combining a certain dose of AstraZeneca vaccine with a certain dose of Pfizer-BioNTech. Professor Gao also suggested to continue research on messenger RNA vaccines: “Everyone should consider the benefits of vaccines [issus de cette technologie] For humanity. We must study them carefully and don’t ignore them, because we already have different types of vaccines. “
After the initial weakness, especially due to the fact that the virus is under control in the country, China has accelerated its vaccination campaign for several weeks. By the end of March, at least 65 million people had received the first dose, of which 34 million had received the second dose. Although China’s Fosun Pharma has signed agreements with Pfizer and BioNTech to produce vaccines in China, so far, China has only approved five vaccines developed in the country, and the agreement has been suspended until the Chinese National Health Commission approves the formula.
Despite the uneven data, China is still working hard to defend the effectiveness of its vaccine. Gao Fu’s comments are surprising. In December, the director of CCCPM even participated in questioning the safety of messenger RNA vaccines in the Chinese population, and said that unknown side effects cannot be ruled out. To this end, Chinese official media and some scientific blogs have also published several articles, using a more mature virus inactivation technology to ensure that it is empty for Chinese products. “I am surprised by what Gao said, not because it is different from what we already know, but because it deviates from the state’s narrative about vaccine effectiveness. China faces Western vaccines.”, Commented on Twitter, Huang Yanzhong, head of international health issues at the Committee on External Relations (CFR) of the Center for American Studies.
