The Joint Scientific Committee of the Center for Health Protection will meet this Wednesday. Xu Shuchang, a government expert consultant and chair professor of the Department of Respiratory System at CUHK, said in an interview with the Commercial Channel program today (24th) that the WHO has updated the guidelines earlier, and the recommendations can be made at the same time. For vaccinations against the new crown and flu, "one shot on the right, one shot on the left." He revealed that the relevant agenda will be discussed during the meeting to give the elderly the feasibility of being vaccinated at the peak of winter flu.
The committee will also discuss the arrangement of the third injection. Xu Shuchang mentioned that due to the raging variant of the virus and the decrease in antibodies over time after the injection, it may be necessary to inject a booster every other year.

Simultaneous flu shots and the new crown vaccine do not affect the protection rate
Xu Shuchang said that the elderly vaccination rate is low, and the Hong Kong government has strengthened vaccination channels, including providing vaccination services in community halls, and the Hospital Authority has also opened up public hospitals to set up vaccination stations.
He mentioned that the WHO updated its guidelines earlier to allow simultaneous flu shots and new crown vaccines, and one shot on the right and left hand, which has little effect on the protection rate of the two vaccines. The expert committee will discuss the relevant practices this Wednesday.
He pointed out that in the peak of winter flu, many elderly people will get flu shots, and they can get the new crown vaccine at the same time.
He also mentioned that many children did not agree to the injections by parents living in institutions because they were uneasy. He pointed out that the media initially widely reported the deaths of elders in Norway and other places after injections, which made the concept of death deeply ingrained. However, most of the elders concerned were over 85 years old. "Death can be explained." He believes that more effort will be needed to reverse the perception of Hong Kong people.
Xu Shuchang said that it may be necessary to vaccinate boosters regularly.

The third shot is estimated to have a problem with the immune system and the first batch of vaccinations for people over 60 years old
Discussing the arrangement of the third injection is also one of the agenda of the meeting, including the priority of vaccination. He believes that kidney or organ transplantation, or people with immune system problems, and elderly people over 60 years old can receive the first batch of vaccination; the second is the frontline Medical and anti-epidemic related jobs.
Coxinga Fubitai has a higher third-injection antibody
CUHK and the University of Hong Kong are conducting the third dose effectiveness study respectively. He mentioned that for the two doses of Kexing that he was responsible for following up, half of the people continued to take Kexing, and the remaining half were transferred to Fubitai. Preliminary data It showed that the antibodies increased relatively after the transfer to Fubitai, but it still needs to be analyzed.
He also pointed out that if the first two doses of vaccines are vaccinated with an inactivated platform, if the third dose is transferred to another platform, such as a nucleic acid vaccine, which is relatively better, it can stimulate the production of more antibodies.
When asked if Israel and others have also studied the fourth injection, whether the vaccination injection will become a regular habit, he said that he may need to receive booster regularly. "It is possible once a year." Because of the raging variant virus and the decline in antibodies after the injection Circumstances, "especially the inactivation falls quickly, so I always have to take a booster."
