The government recently announced that uninfected people aged 18 to 59 who have a higher risk of exposure or personal needs can receive a fourth dose of the new crown vaccine.
Liu Yulong, chairman of the Scientific Committee on Vaccine Preventable Diseases, said on the radio program this morning (23rd) that there have been many misunderstandings about the fourth injection in the past two days. There is no need to be vaccinated, it means "it really shouldn't be vaccinated", which is not a priority. Even after vaccination, there is only one to two more months of protection. Hey, your score has reached 70 points...you can't get any higher."
He continued that only about 20% of the elderly over the age of 80 have been vaccinated for the third dose, emphasizing that the highest priority is to increase the rate of the third dose.

Liu Yulong said on the Hong Kong and Taiwan program "Millennium" that he went to the vaccination center in the past two days and found that the public had many misunderstandings about the fourth shot.
He continued that although it was announced last week that people between the ages of 18 and 59 could get the fourth injection, in fact only a small number of people need it, not everyone between the ages of 18 and 59 needs it, saying, "It really shouldn't be [taken]. ”, its protective power is limited and short-lived, lasting only one to two months.
The risk is not high for medical border inspectors who do quick tests every day and have protective clothing
When asked under what circumstances the above-mentioned age group needs the fourth shot, he gave an example that he may be leaving for a study tour in Hong Kong, where masks are no longer required.
He also said that medical staff and border inspectors are exposed to high risks every day, but they do rapid tests every day and have protective clothing. The risks are not high, but they can judge their needs by themselves.

The injection is like a warm book: "The fourth time I warmed up, the score went to 70 points... There is no frame, no need to be higher."
Liu Yulong emphasized that the role of the vaccine is to prevent severe illness and death. Hong Kong is a few areas where the fourth dose can be vaccinated. Experts also have different opinions. The public can judge whether it is necessary at the individual level.
He bluntly said that with each additional dose, the benefits will be smaller, and there is also a risk of myocarditis. "There is a rule that you keep doing it, and in fact, every time you do it, you will get more benefits than the last time. low".
He continued: "You have warmed the book for the fourth time, you have thought about it, and your score has reached 70 points... There is no way to improve it."

Pushing up the third vaccination rate for people over 80 is the top priority
Although people aged 18 to 59 do not need the fourth injection, Liu Yulong also mentioned that the elderly and chronically ill patients do have their needs.
He went on to say that even after the third injection, the mortality rate in the group over 80 years old was still 1.2%, and the mortality rate could be further reduced after the fourth injection.
He emphasized that the top priority at present is to increase the third vaccination rate for people over 80 years old, which is only about 20% at present, describing it as "dropping sweat".

The current repeated epidemic should be viewed with a normal mind
When asked about the current epidemic, Liu Yulong described it as "the aftermath", and there are still ups and downs, depending on the ability to trace the virus.
He believes that if there is a sixth wave, it will be because of the emergence of new mutant virus strains, but it is believed that the number of cases will only increase, and there will not be too many severe cases and deaths. Even if the Omicron BA.2.12.1 virus may flow into the community now There are mainly young people in the community, and there are few chances of serious illness, so it can be viewed with normality.
