People around the world are battling the Corona virus epidemic, and about 19 million people have been diagnosed with code 19 so far.
But in recent weeks there has been a lot of positive news about vaccines to prevent the disease.
Pfizer and BioNTech released the third phase of human trials of vaccines from Russia and Moderina, in which they proved to be more than 90% effective in preventing the disease.
But will this progress prevent the corona virus and how long will life return to normal?
Get to know the opinions of experts, whose estimates differ from each other, but they are all hopeful that the situation will improve next year.
Experts estimate that the outbreak will be possible only if 70% of the population develops immunity to the virus.
But it is unclear how long such a large-scale vaccination will be possible.
Speaking to CNN recently, Dr. Anthony Fauchi, a leading American epidemiologist, said he hoped the situation would return to normal between April and July.
He thinks this could be possible in the second or third quarter of 2021, especially in the United States.
"Preliminary results from vaccines have been encouraging, but we need to prepare people for the vaccine, after which conditions are expected to return to normal in the second or third quarter," he said.
On the other hand, Ugur Shaheen, a Turkish-born co-founder of the German company BioNTech, which is involved in the development of the fire vaccine, told the BBC that the epidemic would be eradicated.
He said he believed the situation would return to normal within a year and that life would be the same next winter because of the vaccine.
He said further analysis of the Pfizer vaccine is expected to further reduce the rate of transmission between people and prevent the onset of symptoms.
"I am hopeful that such an effective vaccine will reduce the transmission of the disease among the people, perhaps not 90 per cent but 50 per cent, but let us not forget that it will dramatically reduce the spread of the epidemic," he said. Will
Professor Ugur Shaheen said that if all goes well, it is expected that the distribution of vaccines will start by the end of the year or early 2021.
John Bell, a professor of medicine at Oxford University and a co-developer of the university's vaccine, told the BBC last week that he expects life to return to normal before spring next year.
But Julian Haskos, an expert at the University of Liverpool in the UK, told the BBC in October that "life before the epidemic will not be restored for five years".
He said early vaccines may not be financially viable and may not necessarily reduce the spread of the virus to a level that would prevent an epidemic, including years of use of face masks and precautions such as social distance. May have to act.
Not only the manufacture of vaccines but also their packaging and transportation for worldwide delivery is a major challenge.
According to Sarah Pitt, an expert in biomedical sciences at Brighton University, the process of introducing vaccines could take several months, after which delivery could take several months.
