Joint study by the University of Hong Kong and China University: Coxing is not enough to get the 3rd shot of Omicron to get the antibody against Bitex

Since last month, the government has allowed all people who have received two doses of Kexing vaccine to receive a third shot. For the time being, only high-risk individuals can receive three shots for Fubitai vaccine.

However, the recent variant virus Omicron poses a threat to the global anti-epidemic. A joint study by the University of Hong Kong and the Faculty of Medicine of CUHK found that after two doses of Fubitai vaccine, the antibody response to neutralizing the Omicron mutant strain is very low, and all three injections of Fubitai are required. , Or two injections of Kexing vaccine followed by a re-bite booster injection will be enough to resist.

Earlier, Chief Executive Carrie Lam Cheng Yuet-ngor received the third shot of Kexing vaccine, saying that the antibody did not "get higher, the better."

However, studies have pointed out that if Coxing is administered to all three injections, there will not be enough antibody levels to resist Omicron.

Earlier, Beijing Kexing pointed out that all three injections and vaccines can effectively resist Omicron. However, a joint study by the School of Medicine of Hong Kong University and the School of Medicine of CUHK pointed out that the three doses are all people who have received the Kexing vaccine, and there is not enough antibody level to resist. Omicron mutant.

According to the research, Omicron has the ability to avoid neutralizing antibodies that have been infected with COVID-19 or have been vaccinated against COVID-19, and found that after the third dose of Fubitai vaccine, the antibody level can be raised enough to resist the Omicron mutant strain, even with two doses Kexing vaccine, the third injection chooses Fubitai, and there are enough antibodies.

A joint study by the University of Hong Kong and the Chinese University of Hong Kong has shown that the level of neutralizing antibodies is sufficient to resist Omicron for people who have received three injections of Fubitai vaccine, and those who have received two injections of Kexing and one injection of Fubitai.

However, studies have pointed out that if all three shots are vaccinated with Kexing vaccine, the antibody level will not provide sufficient protection.

Pei Weishi, a professor of virology at the School of Public Health of the University of Hong Kong who participated in the study, pointed out that people who have received two doses of Fubitai or Coxing vaccine should get the third dose about 6 months after the second dose to ensure adequate resistance. Resist Omicron.

Xu Shuchang, a government epidemic prevention expert and chair professor of the Department of Respiratory System at CUHK, also called on qualified persons to get a third shot.
