Developed countries around the world have been active in the race to produce a vaccine against the corona virus by early 2021. Johnson & Johnson, one of the world's largest healthcare companies, is also testing the product. Johnson & Johnson plans to produce one billion vaccines against the corona virus within the next year. According to CNN, it plans to start production by the end of this year.
The company's chief scientist, Dr.Paul Stofels as saying CNN quoted that a vaccine against the corona virus would be produced within the next year. Clinical trials are also said to take some time. Countries around the world, including the United States, China, Russia, India, the United Kingdom, Australia, and Israel, are in the race to develop vaccines against the corona virus.
They still don't even know if a vaccine will work for this virus. Any timeline is pure speculation at this point.
