Experts have suggested that vaccination is advantageous in many aspects, as concerns arise that the vaccine may not be effective even if it is infected with the COVID-19 mutant virus.
Professor Nam Jae-hwan of the Department of Medical Life Science at the Catholic University said in an online briefing of the Central Defense Countermeasure Headquarters on the 8th, “The effect of the vaccine has the function of preventing the virus from entering the body, and the other is “There is a function that prevents you from getting sick,” he explained.
Professor Nam analyzed that “all vaccines that will be introduced in Korea seem to be able to somewhat prevent the person who received the vaccination from becoming severe due to viral infection.”
In particular, “Jansen and NovaVax vaccines have been clinically conducted in South Africa by accident and the effect on mutants has been reported.” What prevents you from going is much higher than this.”
He added, “Once you get the vaccine, you can at least think that even if the virus attacks, you will not get sick,” he said. “Don’t worry too much, and once the vaccination sequence comes back, it is very important to get the vaccination. “He emphasized.
According to Professor Nam, all vaccines planned to be introduced in Korea were made based on a virus that was prevalent in Wuhan, China.
However, there have been various mutations since then, and among them, mutant viruses that have stronger transmission power than existing viruses such as from the UK and South Africa have been reported one after another.
Prof. Nam said, “It seems that most of the vaccines currently developed have a sufficient protective effect,” and said, “If you get the vaccine, you don’t have to worry about the UK mutation.”
Regarding the mutation from South Africa, he said, “It is reported that the defense ability of neutralizing antibodies induced by the vaccine is slightly lowered.”
Meanwhile, Prof. Nam said about the COVID-19 vaccine antibody production rate, “The five vaccines that are to be introduced in Korea show an antibody production rate of at least 90% to almost 100%.”
However, it is not well known how long the antibodies produced are maintained, as the period for which the COVID-19 vaccination began worldwide is not long.
In this regard, Professor Nam said, “There is no accurate data on long-term immunity because the vaccination period is very short. Therefore, it is difficult to give an accurate answer to exactly how long the defense capacity of this vaccine is maintained.”
Still, he said, “There are reports that some mRNA (messenger ribonucleic acid) vaccines maintain sufficient neutralizing antibody titer against viral infection 4 months after vaccination.” “The vaccine is already being vaccinated, and this year, there are probably many related data. I’m afraid it will come out.”
