In fact, the problem is very serious. The thing is that the proven vaccine is still not found and people continue to die. Also, outbreaks are constantly recorded in other countries. Today, the virus is already on every continent.
In addition, there is a threat of virus mutation.
Technically flu virus keeps mutating all the time, and vaccines are available to the "past" variants of it, not "current" one. And its mortality is as well similar. The main difference is that coronavirus is a new type of virus.
That's a very important observation, which all of us must think of before panicking. Humanity are dealing with new types of viruses all the time, and biopharmaceutical companies around the world are already accustomed to uniting in struggle against deadly viruses. Their best researchers are now working in cooperation, focusing on developing a vaccine against COVID-19, adapting advanced technologies that were developed for fighting SARS in 2003. No doubt they will succeed in fighting Coronavirus, same as they succeeded in fighting even deadlier things before.
