The government has previously disclosed that if citizens receive two doses of the new crown vaccine 14 days apart, the number of quarantine days can be shortened.
It is understood that the government will announce the details tomorrow (7th).
Professor Pan Liewen of the School of Public Health of the University of Hong Kong said on a radio program that vaccines do not protect everyone 100%. To shorten the quarantine period, it is recommended to cooperate with antibody tests. If the antibody concentration is high and the virus test is negative, multiple protections can be provided.
He believes that because their risk is relatively small, in addition to shortening the quarantine period, when the building is submitted for inspection, it is also worth considering home quarantine, but still subject to compulsory testing.

Pan Liewen emphasized that vaccines do not protect everyone 100%, and some people have the chance to get infected after being vaccinated.
Therefore, he thinks it is necessary to observe the antibody level of the quarantined person. If the virus test is negative and the antibody has a high concentration, it will be safer.
Pan Liewen continued that as far as immigrants are concerned, since they come to Hong Kong from other places, there are many hidden worries. For example, it is difficult to grasp their physical condition, vaccination method or vaccine type, so they need to be reflected in the antibody level.
He pointed out that if there is a high concentration of antibodies after vaccination, the risk will be lower, so shortening the testing period is a "reasonable choice."
When asked whether the quarantine person has received injections and 14 days apart, can frequent virus tests be used instead of antibody tests. Pan believes that if the quarantine person has a low amount of virus, there is a chance that the virus cannot be recovered, so the antibody test can better reflect reality .

Consider home quarantine and still subject to mandatory testing
Recently, the mutant virus has flowed into the community. When there is a case in a building, the residents of the entire building must be submitted for inspection.
Pan Liewen pointed out that if residents have been vaccinated, the rapid test is negative and they have a high concentration of antibodies, their risk is relatively small, and it is worth considering home isolation. At the same time, it can provide incentives to encourage more citizens to vaccinate.
However, he believes that even if the vaccine has been vaccinated, the relevant persons still need to be subject to mandatory testing.
He explained that they had only been vaccinated and their immune response was not yet known, so they must be tested.

Underreporting is not ideal
In addition, the Indian man who was diagnosed with the variant virus and his Filipino girlfriend who lived with him only recently explained that he had participated in the gathering.
Pan Liewen said that he does not comment on whether the incident involves concealment, but the risk can be very high. Referring to the past fitness room, K11 and other groups, one case has been able to infect many people, and the transmission rate of the variant virus is high, so concealment is not ideal .
