To clarify: What OP is referring to as "Coronavirus" is in the scientific sense aka a family of viruses of which SARS-CoV2 and common cold both fall under. "Coronavirus" colloquially refers to only SARS-CoV2 hence the misunderstanding.
OP is saying that he's not surprised to hear that SARS-CoV2, a member of the same virus family as common cold, is following the same fate of common cold of which has an annual vaccine.
It seems intuitive to me that this whole thing will not magically end with a single vaccine. There will likely be enough variations that we will be dealing with future strains like we deal with influenza.
Sounds like a great business plan. Vaccines As a Service
