If the common cold is a type of coronavirus and we're unable to find a cure, why does the medical community have confidence we will find a vaccine for COVID-19?

The "common cold" is not a single virus.  It's a term we use to describe a whole lot of different viruses, some of which are rhinoviruses, some are coronaviruses, and others too, all with varying degrees of danger to health and wellness.

Some of these viruses mutate frequently as well so we can't make one single vaccine that will work for every infectious virus.

The SARS-CoV-2 virus that causes COVID-19 is a SINGLE virus that has a relatively stable genome (doesn't mutate too much).  So we are all over this.  This virus was made for a vaccine.
