Here’s why an effective vaccine cannot be made for COVID-19

Coronavirus is an RNA type virus.
For that matter all cold and flu viruses are RNA type viruses.

To understand the difference between RNA and DNA type viruses…study “RNA Virus Mutation VS DNA Virus Mutation”
After you do this, you will understand why any attempts to manufacture a cold or flu vaccine are scientifically speaking, a waste of time. (Or in layman’s terms “impossible”)
