Let's talk a little more about Corona with Cho Dong-chan, a medical reporter.



Q. Why did Britain declare an endemic disease?



[Cho Dong-chan / medical reporter (specialist): In the UK yesterday (21st), 50,000 people were confirmed and 30 people died.

Still, they saw Corona as an endemic disease and started coexistence again.

Let's see why.

The graph you see now compares the number of deaths before and after Corona.

Above the gray baseline, there are more deaths.

Corona may be the cause.

First of all, it's American.

There were more deaths in 2020 and 2021 at almost all ages, and this year has also decreased, but there are more deaths than before Corona.

This time we will look at the UK.

There has been a significant increase in the number of excess deaths in 2020.

It increased slightly at the end of 2021, but this year it is almost the same as before Corona.

That is why the United States cannot make a declaration of daily recovery, but the United Kingdom does.]



Q. The beginning of endemic disease?



[Cho Dong-chan/medical reporter (specialist): The quarantine authorities are saying that even though the spread continues now, it is in the early stages of an endemic disease.

Let's look at the graph.

If you look at the graph of excess deaths in Korea, it is almost the same level before and after Corona.

It's thanks to the world's highest vaccination rates and high standards of medical care.

Just looking at the indicators, it seems like we can declare a daily recovery like in the UK, but I don't think it's possible right now because the Omicron is on an upward trend.]



Q. How many vaccines should I get?



[Cho Dong-chan/medical reporter (specialist): He said that he had to get the Modern NASA corona vaccine every year.

The University of Pennsylvania said in an interview with the New York Times that three times would be enough.

The U.S. Centers for Disease Control and Prevention announced on the 11th.

The third dose was effective in preventing infection for just four months.

This is because antibodies that completely block the virus decrease rapidly after four months.

However, since we can't get it every four months, we have to get it every year.

On the other hand, the antibody that blocks the virus disappears quickly, but the T-immune cells that fight off the virus that enter the body are maintained for several years.

A person who contracted SARS in 2003 introduced a case in which T-immune cells were activated again in 2020.

If it is the standard of confirmed cases, it should be met every year, but if it is the standard of severe severity, it can be considered that three times are sufficient.

However, for those with compromised immunity and residents of nursing homes, there is controversy for the prevention of serious illness, but the government is proceeding with the fourth vaccination.]
