Covid-19 may not go away with vaccine

Vaccine researcher at the University of Texas Medical Branch thinks that the dangers of Covid-19 may be mitigated by public immunity, but are unlikely to disappear entirely.
Mr Vineet Menachery, a nCoV researcher at the University of Texas Medical Branch, told NPR’s Weekend Edition about his predicted future world outlook. One of the most likely scenarios is that the rate of spread of Covid-19 will slow down due to community immunity.

“I would be surprised if we still wear a mask and keep a distance of 6 meters from others for another two or three years. And during that time, Covid-19 could turn into a disease similar to a cold. usually, it’s not too serious, ”said Mr. Menachery.

There are more than 20 million people infected with Covid-19. Of which, over 730,000 people died. In the US alone, there were nearly 5.2 million infections and more than 165,000 deaths. While scientists are racing to find a cure, they still cannot rule out the possibility that the disease will never go away completely, with vaccines or not. But according to Mr. Menachery, these figures do not mean that people around the world must keep a safe distance to prevent diseases forever.

In fact, scientists have failed many times to destroy many types of viruses. Except for smallpox which is actually eliminated, many other viruses still exist. Menachery said Covid-19 could be terminated around the world like humans did with SARS in 2002. But as with SARS, nCoV or the like, it will remain. in nature. At any time they can reappear and infect people.

Covid-19 bears the same characteristics as a common cold with a high degree of infection, but it is much more serious and affects the world heavily in many ways. With the common cold virus, the human body’s immunity to them does not last long. And with the nCoV virus too, there is no guarantee of how long the immune system will work and that people can be re-infected with the disease. Whereas viruses such as SARS and MERS, if a person has been infected, the person will develop an immune mechanism, which will usually last for a long time.

Like many scientists before that, Mr. Vineet Menachery said that the best way to develop community immunity is through a preventive vaccine and certain groups have been exposed or will be exposed.

Menachery said that nCoV would eventually be like OC43, a common cold-causing corona virus that originates in cows. Historically, it has been reported that there has been an outbreak of disease involving the conversion of the virus from cow to human and causing very severe symptoms. A few years later, OC43 was just a common cold virus.

“So I believe that in the next few years, the world may return to normal even though Covid-19 still exists, but it will just be a common cold with less serious symptoms”, Menachery said.
