Lots of Time Are Required to Develop A New Drug

I think time to develop a new drug will differ depending on the nature of the virus; however, I think more than 10 years are required to develop any complete medicine. First of all, researchers have to find out the characters of the virus to guess which kinds of components can be useful to remove the virus. For example, researchers found out that coronavirus has a special character which is different from other viruses, and judged that it will take many times to develop a new vaccine of coronavirus because of its instability. After that, researchers have to perform clinical trials. They can choose animal testing or they can test a new vaccine to people directly. This will process will take a very long time, for researchers must acknowledge every side effect. In addition, if the virus is very dangerous that can lead many people to die or to be infected, the government tries to distribute the medication to all citizens by not giving any patent to the particular enterprise.
