In Turkey, Brazil and Chile, the diagnosis rate continues to rise after receiving the Chinese Kosin vaccine, and the Philippine Presidential Security Guard has also revealed that many people have been diagnosed after receiving the Chinese national vaccine. The U.S. media revealed that Gao Fu, director of the Chinese Center for Disease Control and Prevention (CDC), recently made a rare admission about the low effectiveness of Chinese vaccines.
The Chilean Catholic Church confirmed on its official Twitter account on Oct. 10 that Aios, 76, and Auxiliary Bishop Alberto Lorenzelli were both diagnosed with Wuhan pneumonia a few days ago and have been admitted to a hospital in Santiago for treatment. In a statement, the church said they had both previously received two doses of the vaccine developed by the Chinese company Kexing, and the second dose was administered on March 11, further reinforcing international questions that the actual protection of the Chinese vaccine “may be very low.
According to the Associated Press, Gao Fu, director of China’s CDC, admitted at a seminar in Chengdu, Sichuan province, on March 10 that the Chinese vaccine’s “protection is not very high. He also revealed that the authorities are studying two ways to address the problem of low protection of the existing domestic vaccines, either by increasing the dose or adjusting the interval between vaccinations, or by considering a mixture of vaccines developed with different technologies to improve protection.
A hospital quarantine worker in Xi’an, China, who had already received two doses of the domestic vaccine, was also diagnosed with Wuhan pneumonia on March 18. Gao Fu later explained in an interview with the Chinese Communist Party’s official media that there are three possible scenarios: first, the vaccine may have produced antibodies in the body, but the virus infection is in the respiratory tract; second, the quarantine worker may be a non-responder to the vaccination; and third, “it may be that after two doses of inactivated vaccine, the antibody titer is not enough and a third dose may need to be made up “, making many Chinese netizens exclaim: “How many doses of vaccine are needed to provide protection in the end?”
Countries such as Turkey, Brazil and Chile have all recently launched large-scale vaccinations against Coxin China, but the outbreak in these countries has not abated and the confirmation rate has increased rather than decreased. The University of Chile recently published the results of a study of vaccination data and infection rates across Chile, which showed that after two weeks of vaccination with two doses of the Coxin vaccine, the efficiency of prevention of Wuhan pneumonia was only 5 with 4%. Data from phase III clinical trials of the Chinese Coxin vaccine, published by Brazilian researchers in February of this year, also showed that the vaccine provided only 50.4 percent protection.
To combat the Wuhan pneumonia outbreak in China late last year, countries have stepped up efforts to develop, review and purchase vaccines for administration. The Chinese Communist Party authorities have been engaging in “vaccine diplomacy” this year with some economically and technologically backward countries in an attempt to expand China’s international influence by providing vaccines to them. To date, however, the World Health Organization (WHO) has not approved the emergency use of any of the Chinese Wuhan pneumonia vaccines developed by Chinese companies.
