Hong Kong’s new crown pneumonia vaccination program has been launched for more than two weeks. The dean of the Hong Kong University School of Medicine and the government’s anti-epidemic expert consultant Liang Zhuowei stated on the commercial channel today (13th) that there is a phenomenon of "vaccine hesitation" all over the world, but the protective power of masks At only 15% to 20%, Kexing vaccine is three times as effective as masks, and Fubitai vaccine is 4 to 5 times more effective.
He emphasized that the expert's recommendation to approve the emergency use of the vaccine is a deliberate one, "it must be that the benefits outweigh the risks."
At present, about 160,000 citizens have received injections, accounting for only about 2.2% of the total population of Hong Kong.
Liang Zhuowei said that at this rate, it is estimated that it will take two years to vaccinate the entire population.
He believes that the authorities issuing specific vaccination guidelines for chronically ill patients will help doctors give them injections.
The Faculty of Medicine of the University of Hong Kong will operate the vaccination center at Ap Lei Chau Gymnasium, and the public will be vaccinated from next Tuesday (16th).
Several professors will lead the research and recruit volunteers at the center.

Leung Cheuk Wai, Dean of the Faculty of Medicine of the University of Hong Kong and an expert consultant to the government’s anti-epidemic said, Hong Kong people often think that masks are a panacea for epidemic prevention. In fact, their protective power is only 15% to 20%. The effectiveness of Kexing vaccine is three times that of masks. The vaccine is up to 4 to 5 times.
He understands the phenomenon of "vaccine hesitation" all over the world, but emphasized that experts have read thousands of pages of documents for each vaccine, and that emergency use is approved after careful consideration. "It must be that the benefits outweigh the risks."
At present, about 160,000 citizens have been vaccinated, accounting for only about 2.2% of the total population of Hong Kong. If this rate is used, it is estimated that it will take two years to vaccinate the entire population.
"No one is truly safe, until everyone is safe." He urged the public to cherish the vaccine, especially Fubitai needs to be thawed and diluted, and if you give up the vaccination, you should cancel the appointment.

Leung Zhuowei said frankly that he is not entirely sure that the deaths and critical cases have nothing to do with Kexing Vaccine, but Kexing may not be the only one in this situation. It is the first to launch Kexing in Hong Kong, and the number of vaccinations is relatively large.
He pointed out that several European countries have discontinued the AstraZeneca/Oxford vaccine, which is believed to be involved in blood clotting problems, and several deaths in Hong Kong have also experienced cardiac embolism.
In addition to studying the anatomy report and comparing the unusual signs in the past 4 to 5 years, the experts will also conduct a case study. The control group includes acute deaths, such as car accidents, poisoning, and other cases that are definitely not related to the vaccine.
Liang believes that the authorities issued specific vaccination guidelines for chronically ill patients to help doctors give injections to patients, but each patient's medical history and medical history are different, and family doctors know best whether their condition is under control.
He reminded that for chronically ill patients who have not managed their heart problems well, they should stop and think about it before getting the injection, and don't rush for a while.

In terms of vaccine selection, Liang Zhuowei said that Kexing and Fubitai vaccines are developed by different platforms. Kexing is a traditional inactivated vaccine. Fubitai uses new technology, but the efficiency should be the highest.
Millions of people in Israel have been vaccinated with the Pfizer vaccine/BioNTech vaccine (same version of Fubitai) and found that the effect is similar to the research data.
He also said that Fubitai has been confirmed by research to be effective against the B117 variant virus circulating in Europe, America and Canada, and people who need to work on business can consider vaccination.
As for the side effects and reactions, many people have a greater reaction after vaccination with Fubital, especially young people have better immune systems. After the second dose, they are prone to symptoms such as mild fever, fatigue, and chills.
Severe allergic reactions such as facial paralysis, facial swelling, dyspnea and other side effects will occur in one person per 1 million people inoculated with Kexing; and 4.7 people in every 1 million people inoculated with Fubitai.
