From now on, we will discuss this with Cho Dong-chan, a medical professional reporter, on what to do so that our daily life is not taken away by Corona again.



Q. Is the 'boost inoculation' valid?



[Cho Dong-chan / Medical reporter (specialist): Let's first look at the structure of the Omicron mutation that the Italian research team studied last night (28th). Marked in red is the mutated part of the spike protein, which is responsible for penetrating the body. There are 18 deltas and 43 microns. Therefore, the opinion of domestic vaccine experts is that even if the vaccine is added now, it is unlikely that Omicron will do well. The effectiveness of the current vaccine for Omicron is expected to come out in about two weeks.]



Q. How effective is the Omicron customized vaccine?



[Cho Dong-chan / Medical reporter (specialist): It is possible to make a customized Omicron vaccine by early next year, but it will take more time to fully verify the effectiveness and side effects. Although Omicron is highly contagious, it is not yet known how deadly it is. However, if the fatality rate is low, there is no need to get a vaccine that has not been fully verified too quickly. The quarantine authorities also said that they would respond flexibly according to the future research, but the booster vaccination is important because the elderly over 60 need to lower the current delta mortality rate with the booster vaccination.]



Q. What is the risk of Omicron?



[Cho Dong-chan/medical reporter (specialist): The president of South Africa said that the symptoms of omicrons were mild. Why did you say this, let's see.

If you look at the graph of the recent corona virus in South Africa, the number of confirmed cases has been increasing rapidly since two weeks ago.

The positive rate compared to the test also jumped 4.5 times from 2% to 9%.

Because of the micron mutation.

But let's look at the death graph.

It continues to be low at less than 1 in 1 million people.

I'm glad.

However, it usually takes about 10 days for a confirmed diagnosis to worsen to severe disease, so we will have to wait another two weeks.]



Q. What about the existing vaccines?



[Cho Dong-chan/Medical Correspondent (specialist): I will introduce you to the recent Nature thesis.

When the research team tested a lot of mutations, both those who were vaccinated and those who were naturally infected became infected, but only those who were naturally infected were protected by the vaccine.

It means that it is not easy to mutate again in the future with only the existing vaccine, so there is another homework to solve.]
