The world scientific community started researching a possible preventative vaccine against the coronavirus, when the outbreak started showing signs of developing into a full-blown pandemic.
The containment strategies adopted by various governments can only slow the process of the spread. But, they cannot completely prevent the virus from infecting a person. As soon as the WHO declared COVID-19 pandemic, the next step was to look into the possibility of developing a vaccine.
At the moment nearly 35 companies are competing to develop a vaccine. And, four companies have already stared trials on animals. One of the companies, a biotech firm called Moderna based in Boston is confident that they can go into human trials quite soon.
It was China that initially sequenced the genetic material of ‘Sars-CoV-2’. It is the virus that causes Covid-19. China shared this sequence with the scientists around the world in early January. And, this expedited the research process in developing a vaccine.
