Hong Kong's new crown vaccination plan was launched at the end of February, and Thursday (18th) has entered its 21st day.
The Scientific Committee on Vaccine Preventable Diseases and the Scientific Committee on New Discoveries and Animal Infectious Diseases under the Center for Health Protection of the Department of Health held a joint meeting on Thursday. The director of the Center for Health Protection Lin Wenjian later said that when the vaccine coverage rate increases to more than 50%, conditions are available. Consider relaxing some social distancing measures; and in some places, such as nursing homes, if the vaccination rate is as high as 100%, visits can also be relaxed.
The committee also pointed out that the BioNTech vaccine currently used in Hong Kong has a protection rate of 85% to more than 90% against the variant virus strains in the United Kingdom and Brazil, but it is "not effective, but effective" against the variant virus in South Africa. As for the Coxing vaccine, there is still no data to prove whether it is effective against the mutant virus.

According to the authorities, there have been nearly 450 imported cases in Hong Kong in the past three months, of which 93 were mutated virus strains, which were divided into 37 cases in the United Kingdom, 8 cases in South Africa, and 5 cases in Brazil. The remaining 43 cases are still subject to genetic analysis.
Liu Yulong, chairman of the Scientific Committee on Vaccine-Preventable Diseases, said after the meeting that Fubitai vaccine is effective against variant virus strains in the United Kingdom and Brazil, but it is "not effective, but effective against variant viruses in South Africa."
Kexing vaccine has no data showing that it is effective against variant viruses
As for the Coxing vaccine, Liu Yulong said that there is still no data to prove whether it is effective against the mutant virus.
The AstraZeneca vaccine that the Hong Kong government plans to purchase is effective against the variant viruses in the United Kingdom and Brazil, but "basically ineffective against the variant viruses in South Africa." As to whether the government would recommend that the government cancel the purchase of the AstraZeneca vaccine, he reiterated that this was not a committee decision. Should be considered by the government.
He also pointed out that there are reports in the United Kingdom showing that the virus variants can make the disease more serious, so in the future, we will still strictly prevent imports and increase the vaccination rate.

Lin Wenjian reiterated that it is important for those who have received the vaccine to "complete two doses", because only one dose of antibody is not enough. "The second dose will provide sufficient protection." He also pointed out that a recent case was diagnosed after vaccination. Reflecting the low level of vaccine coverage, it is necessary to relax epidemic prevention measures "be cautious." The combination of social distancing measures and vaccines has the greatest power.
Lin Wenjian: If the vaccination rate of elderly homes reaches 100%, visits can be relaxed
Lin also pointed out that social distancing measures need to be relaxed in stages. At present, local cases have not been "cleared", and cases of unknown origin reflect that there is still invisible transmission in the community.
If the vaccination rate is increased to more than 50%, "a certain measure can be relaxed"; if the vaccination rate in some places, including homes for the elderly, is as high as 100%, it is also possible to consider relaxing visits.
Liu Yulong pointed out that the requirements for herd immunity are high, and the world agrees that if the vaccination rate reaches 75%, you can "really consider that international mobility can be relaxed." He also mentioned that hospital visits and meeting with the elderly are all considerations. Column, "As long as everyone is united, it can happen gradually, but not soon."

Lin Wenjian also admitted that different countries may have mutual certification of different types of vaccines, but reminded the public to consider that the benefits of vaccines outweigh the risk of infection. He also pointed out that "you should be yourself first, and then travel or travel abroad." He added, Whether or not customs can be cleared after the needle is completed is not only a scientific issue, but also involves the policies of different countries and cannot be commented on.
He mentioned that the WHO still believes that the implementation of vaccine passports is immature, because there is still a shortage of vaccines worldwide. If it is implemented, people in developing countries will not be able to travel abroad, causing unfairness.
Xu Shuchang: Recovered patients can wait 90 days after being discharged from the hospital before being vaccinated
Xu Shuchang, chairman of the Scientific Committee on New Discoveries and Animal Infectious Diseases, pointed out that because people who have been infected with the new crown virus have antibodies in their bodies that can last for 6 to 9 months, those who have recovered should be vaccinated in the future, and they can choose a nucleic acid vaccine: That's enough, because the antibody level is already very high, and it obviously stimulates the immune system, and it seems to respond to two injections." He also pointed out that recovered patients do not need to "hurry up for injections," and they can wait 90 days after they are discharged from the hospital before being vaccinated.
However, he admitted that there are no complete data on vaccines such as Kexing that use inactivated technology.
