Earlier, there were media reports that the government was discussing the need for a third vaccine in the future.
The director of the Infection and Infectious Diseases Center of the University of Hong Kong, Ho Pak-liang, stated on a radio program today (13th) that the general public does not need to consider the third shot for the time being unless there are occupational factors or plans to visit high-risk places.
However, since a large proportion of people in special groups have no antibody response after the two injections, the government can recommend the third injection.
He also pointed out that if two doses of the vaccine have been vaccinated, referring to global data, some patients have milder illnesses, and the effectiveness of preventing severe illness and death is 90% or more.

He Boliang quoted the World Health Organization as saying that more than 70% of the world’s population failed to receive the first dose of the vaccine, while some citizens in rich countries have already received the injection. Three needles were donated to people in need, and believed that there was a justification for public health ethics.
He Boliang pointed out that the United Kingdom will implement the "third needle" in September this year, and Israel also has related plans.
He pointed out that these places have several things in common, including that a large proportion of the public has already received two injections and a long time has passed. Therefore, relevant immunization data have been accumulated, including the decline in antibody levels of high-risk individuals.
In addition, these places are planning to unblock them, so some people are considered to be vaccinated with the third dose.

It is expected that only tens of thousands of people belong to special groups
He Boliang said that regardless of whether they are vaccinated with Kexing or Fubitai, the general public need not consider the third dose of vaccine.
Unless you have received organ transplantation or bone marrow transplantation, hematology cancer, patients with autoimmune system problems, or people who are taking oral high-dose steroids and other drugs, there is scientific evidence that even after two injections, a large proportion of them have no antibody response , Or the level of antibody response is low.
He said that the government can recommend a third shot for the above-mentioned special groups of people, and it also proposes to test for their antibodies. If the standard is not met, the third dose of Fubitai will be given. It is expected that only tens of thousands of people will be involved.
The UK does not give the third shot for everyone
He continued that in the UK, for example, they do not give everyone the third shot, but only a small number of people. For example, they only focus on the elderly over 70, residential homes for the elderly, and people with immune system problems.
He explained that these people may have no antibody response or low response after the second dose due to age or disease.
Cui Junming expects that it is only a matter of time before the Hong Kong government discusses with drug manufacturers to purchase the second-generation vaccine for the third injection.
