When a virus outbreaks it take time to understand its behaviour as how it spreads, causes of its spread and most importantly how it is generated or from what source it has come. Scientist, pharmaceutical companies, laboratories across the globe are in race against time to first understand the virus and then develope a vaccine for its prevention and cure. Usually it takes long time (maybe two ro three years) to develope a vaccine for any kind of virus but as corona virus (Covid-19) is a pandemic scientists are trying their best to develope a vaccine for (COVID-19) corona virus but it is still under early stage of development until then "Prevention is better then cure".
