Four of them cause about 15% of common colds that people get. (Most of the rest are caused by rhinoviruses.) One is SARS. One is MERS. And the last is the current COVID-19.
Of those coronaviruses that infect humans, guess how many have successfully had a vaccine created to combat them??
Unless there's been some earth-shattering research breakthrough regarding corona virus treatment, I don't think people should be holding their breath waiting for a vaccine.
