Developing a vaccine is a serious job. Post the outbreak of Covid-19, many agencies in the world have started working towards the development of a vaccine to stop the spread of Coronavirus. At present, the usable vaccine is still a few months or a year away. As per the World Health Organisation (WHO), currently around 60 vaccine candidates are in the pre-clinical trial stage. For any vaccine to reach the stage of public distribution, normally takes around 12 to 18 months. It is expected that by January/February 2021, the Covid-19 vaccine could become available.
