The antibody level of people who have injected the Kexing vaccine is often or insufficient. A study by Xu Shuchang, Chair Professor of Department of Respiratory System at Chinese University, found that the antibody level of the vaccinator had fallen to a low level within a few months, which surprised him. Today (18th) will be Some people received the third injection, half received the Kexing vaccine, and the other half received the Fubitai vaccine.

Xu Shuchang said on the commercial radio program that 700 people were recruited at the vaccination center on April 1 this year. Among them, 350 were vaccinated with Kexing vaccine and 350 were vaccinated with Fubital vaccine. He was surprised that 80 of the 160 KX vaccinators had a low level of antibodies for the new coronavirus. He was surprised that they would be given a third shot. Today, there will be more than 20 people. Going to the Zhongda Hospital for an injection, next week, there will be more than 20 people who are given the Kexing vaccine, half of them, 40 people, and the other half, 40 people being given the Fubitai vaccine.
He quoted Kexing Pharmaceuticals as saying that the third dose of Kexing vaccine can increase the antibody level by seven times, and there are mixed-injection studies overseas, hoping to provide the government with answers to the antibody level of mixed-injection.
However, he said that in addition to antibodies that can protect the vaccinated, the vaccine will also stimulate T cell protection in the body. The protection of Kexing and Fubitai vaccines are similar and can avoid the risk of severe illness and death after infection. Antibodies are used to prevent the onset of disease after infection. .

Medical experts have recently urged the public to abandon the idea of immune barrier. Xu Shuchang said that "it is not the same way of expression, and everyone must always build an immune barrier." Quoting Singapore and the United Kingdom experience, as long as the vaccination rate reaches 70 to 80%, the vaccination rate of high-risk groups is high. Even if there is an outbreak of an epidemic, the medical system will not collapse, but the vaccination rate in Hong Kong is still only 55%, and there is no condition to substantially relax the epidemic prevention regulations.
Zeng Qiyin, the co-chairman of the Infectious Disease Advisory Committee of the Medical Association, said on the Radio Hong Kong program that he should be careful to interpret the saying "abandon the immune barrier." Don’t wear a mask, you can still get infected and spread”, which also implies that even if the vaccination rate is high, the epidemic prevention regulations may not be loosened in a short time.
