<Anchor> Let's



continue to talk a little more with medical reporter Cho Dong-chan.



Q. Is the 3rd vaccination over? Does it lead to 4th or 5th?



[Cho Dong-chan / Medical reporter (specialist): Earlier this year, I reported that if I achieve 80% of the second dose, collective immunity will develop and we can all return to our daily lives. But now, it is reported that the third vaccination is essential. According to the Nature paper, the effect of the third inoculation was predicted to be short-lived. The possibility of the 4th and 5th inoculation cannot be excluded. Even the best vaccine experts in Korea said that the third vaccination is necessary to reduce the death toll this winter, but the need for the fourth and fifth vaccinations should be judged scientifically and calmly while watching follow-up studies.]



Q. What is a special measure?



[Cho Dong-chan / Medical reporter (specialist): Yes, there have been many domestic and foreign studies that strong social distancing is not as effective as expected. We also practiced strong social distancing for the past year. Those in their 20s and 30s who are self-employed and insecure at work have suffered the damage, and I hope that from now on, it will be a scientific method rather than strong social distancing in an unscientific way. And the special measures inquired by the medical community are to postpone surgery for non-urgent patients at private tertiary hospitals, etc., and to drastically increase the rate of switching to the Corona 19 ward, but the backlash from the field doesn't seem to be formidable.]



Q. Obesity is more dangerous ?



[Cho Dong-chan / Medical reporter (specialist): If you are obese, the fatality rate of Corona is twice as high.

Let's take a look at patients with severe corona virus.

Viruses are so small that they cannot even infect others, and neutralizing antibodies are higher than those in mild patients.

That's why I don't take antiviral drugs or antibody treatments for critically ill patients, but I assumed it was because of some bad inflammatory reaction after the virus passed.

A US research team has found that corona cells not only infect mucosal cells, but also infect fat cells, causing them to secrete bad inflammatory substances.

It explains well how obese patients become critically ill due to a bad inflammatory response when they contract the corona.

Even if you are young, if you are obese, do not be vigilant and follow the vaccination and quarantine rules carefully.]
