The common cold comes from a corona virus
12-20% of the “common colds” come from any one of four different viruses in the coronavirus family. About 40% are caused by a rhinovirus. In all, about 200 different viruses cause the symptoms we collectively refer to as “the common cold”.
That’s also why there’s no vaccine for the “common cold”. To develop and test a vaccine against over 200 different viruses would cost a fortune. And nobody’s going to pay $30,000 to avoid getting a cold. So no vaccine.
