Will Coronavirus burn out naturally even before the vaccine arrives?

The former Director of Cancer programme of the World Health Organisation (WHO), Professor Karol Sikora, revealed that the deadly coronavirus might burn out naturally. He said that the process could take place even before a vaccine would be developed.
Professor Sikora tweeted and said, "There is a real chance that the virus will burn out naturally before any vaccine is developed. We are seeing a roughly similar pattern everywhere - I suspect we have more immunity than estimated. We need to keep slowing the virus, but it could be petering out by itself."
