In the post vaccine era, what will the Corona 19 virus remain for us?
To date, more than 20 million people around the world have received the corona vaccine. Scientists hypothesize that when the day comes when a large number of people complete vaccinations, Corona 19 seems to be a’common cold’ that bothers us around us, but is not threatening.
This is the content of a thesis by a research team at Emory University in the United States published in the international scientific journal’Science’ on the 13th.
The Corona 19 virus is currently a threatening and gloomy existence. Because the human immune system is not trained to fight this pathogen, the situation is overwhelming.
However, as we continue to be attacked by Corona 19, our ability to cope with it will also improve. Eventually, they will be able to competently respond to Corona 19, and the possibility of this infectious disease remaining as an’endemic (periodic outbreak)’ increases.
Will remain like a common cold… The timing depends on the vaccination rate
In order to predict the fate of the corona 19 virus’Sas-Cove-2′, the Emory research team looked at four coronaviruses that cause common colds, and another coronavirus, the SARS virus and MERS virus.
The four coronaviruses that cause colds are circulating around us in an endemic way, but they are only mild symptoms when infected. Usually, between the ages of 3 and 5, you first encounter the virus and catch a cold. On the other hand, SARS and MERS viruses, which appeared in 2003 and 2012 respectively, cause more serious symptoms, but are characterized by not spreading widely around the world.
As a result of studying these viruses, the research team predicted that SARS-Kov-2 would remain in a more similar form to the coronavirus that causes colds than SARS or MERS.
So when will it reach endemic? This depends on the rate of spread of the virus, the rate of vaccination, and the strength and retention of immunity after vaccination. The research team thought that it could take two to three years as short and several decades as long. Eventually, the speed of vaccination seems to be the dominant force.
What if there was no vaccine? To the endemic, more and more people have to pay the price of reaching a critical condition or dying. Vaccines have a positive function to shorten the time to enter the endemic and prevent more victims from occurring.
The concept of ending is irrelevant… May remain like the flu
However, vaccination does not mean eradicating Corona 19. Being endemic means that Corona 19 will not end. Scientists believe that Corona 19 will not disappear easily. However, it seems to be hovering around us in a more docile state.
Until the endemic is reached, constant caution is needed even after vaccination. According to Dr. Jennifer Gomerman, an immunologist at the University of Toronto, when directly infected with the coronavirus, a strong immunological reaction occurs in the nose and throat, but the vaccine currently being vaccinated does not cause a natural immune response in the upper respiratory tract. It doesn’t mean you’re completely free.
It is possible that the fate of Corona 19 will flow in a different direction from the hypothesis of this research team. Professor Mark Lipsich of Harvard University’s Graduate School of Health believes that Corona 19 may remain in a more similar form to seasonal flu than a cold. Sometimes it is meek, but sometimes it will appear in a more lethal form. If a new variant emerges in the future, the scenario may flow in an unexpected direction. Prof. Lipsic said that the possibility of remaining with a common cold is the most promising, like the Emory research team’s hypothesis, but explained that it is not 100% guaranteed.
Then, in what form did the coronaviruses, which are now common cold-causing viruses, first appear? One of the four coronaviruses the research team looked at is a virus that killed 1 million people around the world due to a pendemic in 1890. This virus that caused the pandemic eventually remained around us as a virus that caused common colds.
