No treatment has yet been received for the epidemic coronavirus but the discovery of the corona vaccine is still going on globally. In all this, the World Health Organization has warned the world that it may be possible that the coronavirus vaccine could never be obtained. WHO director Tedros Adnom Gabries said this while leading a virtual meeting. He said in his statement, 'many medicines are facing a trial of Phase III. With which it is hoped that soon its effective vaccine will be available in the market. So that people can get rid of corona infection. However, at the moment there is no effective treatment for it, and it may be that effective treatment is never found. On the discovery of the worldwide corona vaccine, Gabries said, 'It seems that we do not find any effective corona medicine or it should only work for a few months. But until we complete the clinical trial, we cannot know anything about it.' The WHO chief urged people to continue with measures like wearing masks, social distancing, washing hands, and conducting tests. The mask should be considered a symbol of solidarity in the world.
