Producing a working coronavirus vaccine could be nearly impossible, believe a lot of scientists globally. Several health officials believe that people may just have to live with coronavirus and be under constant threat of suffering from COVID-19.

Scientists are concerned about the possible production of a viable vaccine based on the fact that no vaccine for any coronavirus infection reports earlier has been approved for use either in the U.K. or the U.S.

Christopher Whitty, U.K.'s Chief Medical Officer recently tole the parliamentary committee that there is mounting evidence suggesting that a vaccine may not be able to produce the natural immunity in people against the COVID-19 infection.

"The first question we do not know is 'do you get natural immunity to this disease if you have had it, for a prolonged period of time?’,” Whitty said.

He further added that if the natural immunity to the virus is not known then it does not make the production of a viable vaccine impossible but much less likely. Nothing is known with complete certainty at the moment.

Another fact which is more concerning is that many patients around the world have been tested positive again for COVID-19 after being treated and reported negative at the time of discharge.

In the case of other coronaviruses, the immunity of the patient has shown to wean off relatively fast. Therefore, it would be not alright to believe at the moment that the coronavirus vaccine, if produced, would be viable and protect against COVID-19 infection for a lifetime, as done vaccines procedure for other infections such as measles and smallpox.

The professor of global health at Imperial College London, David Nabarro, believes that the world is going to live with the consequences of the coronavirus pandemic for a long time and people should not expect a coronavirus vaccine to come in the short-term.

“ For the foreseeable future, we are going to have to find ways to go about our lives with this virus as a constant threat to our lives,” he said.

According to Nabarro, people around the world will have to continue the drill of isolating those who show signs of coronavirus infection and those who came into their contact. Also, they will have to protect the elderly. It is going to become the new normal for the global population.

Even though having a fully viable vaccine seems a distant possibility at the moment, it may still be possible to have a vaccine with a mild response. This may protect people against severe COVID-19 infection, if not against the infection itself.

The coronavirus vaccine may be less effective but sufficiently effective to prevent fatalities across the world.

Coronavirus COVID-19 Laboratory Test, Cure, Vaccine

The Ministry of Health convened The Technological Vaccine Center of the Federal University of Minas Gerais laboratory to conduct research on the coronavirus (COVID-19) in order to diagnose, test and develop a vaccine. According to the Ministry of Health, as of Tuesday, March 24, Brazil has 1.891 confirmed cases of the coronavirus (COVID-19) and at least 34 recorded deceases. Pedro Vilela/Getty Images
