The trial of the experimental vaccine prepared by British scientists for the treatment of corona virus is reaching the next stage and if successful, preparations are being made to apply it to more than ten thousand people. It is noteworthy that last month researchers at the University of Oxford began trials on more than a thousand volunteers to test the effect and safety of experimental vaccines. Scientists announced on Friday (22 May) that they now plan to test the vaccine on 10,260 people, including children and the elderly, across the UK.
Andrew Pollard, who is leading the team developing the vaccine at the University of Oxford, said, “Clinical studies are progressing very well and we are going to start testing this vaccine in the elderly as well to find out To know if this vaccine can provide protection to the entire population. “

Earlier this week the drugmaker Astrazynga said it had signed up for 400 million doses of the vaccine developed by Oxford University. The US government agency has invested $ 1 billion in the development, production and distribution of the vaccine. Nearly a dozen potential vaccines for the treatment of corona virus have reached or are about to begin testing to begin testing on humans. Most of these are from China, America and Europe and dozens of other vaccines are in the early stages of development.
Till now scientists have not developed any vaccine in such a short time and it is not clear yet whether these vaccines will ultimately prove to be safe and effective. There is a possibility that the vaccine, which initially appears to be effective, may fail large-scale testing. So it is very important. Many potential vaccines are being developed with different technology and this increases the expectation of at least one to be successful.

Most developing vaccines try to develop immunity in the body so that the body can recognize the proteins present on the surface of the new corona virus and destroy it before the actual infection occurs. The vaccine formulated by the University of Oxford has used non-damaging chimpanzee cold virus. Changes have been made in it so that the body becomes full of proteins that fight the corona. The Chinese company is also developing vaccines on the same technology.
Other major contenders to develop the vaccine against the corona virus are the US-based National Institutes of Health and Moderna Inc. and Invio Pharmaceutical. Both vaccines are being tried to transcribe the genetics of the corona virus into the body to develop self-resistant proteins (endobodies) that are essential for immunity.
Meanwhile, companies and governments are focusing on increasing vaccine production so that millions of doses of successful vaccines can be produced. It is believed that it is like gambling for companies and governments. If it fails, a huge amount of money will be wasted, but fortunately if successful, people can start giving vaccines on large scales within a few months.
