You can say in more detail why blockchain technology can repel this dangerous disease caused by new virus strain Corona. I only know that scientists specialized in microbiology can develop vaccines to prevent this virus for the world community. And it will take at least a year for the vaccine to become available for this new strain. That will create a new global economic crisis.
I am hoping that they can identify an effective vaccine sooner as they are already doing clinical trials. Multi-million dollars are being allotted to the development of this vaccine. If they will release the vaccine earlier than expected, I think we will go back to our normal lives.
