Of course it is. So is the plague, polio, small pox...
You can reach herd immunity without a vaccine, once enough people have exposed.
Depending on how contagious the disease is, 50 - 90% of the population need exposed before it goes away, which it will all by its own once we reach that point. As thousands of times before in the history of mankind (viruses existed before the US media and politics discovered them), this virus will simply disappear once the paths of transmission are closed regardless of what protective measures we take which merely “delayed” the inevitable without a viable vaccine.
Smallpox and polio didn’t disappear because enough people were exposed. They disappeared because vaccines basically wiped them out.
Smallpox had been around for 2,300 years. You think it’s a coincidence that after 2,300 years of killing hundreds of millions of human beings around the world, smallpox just suddenly hit the surrender button 9 years in to a worldwide mass vaccination effort?
There’s nothing inevitable about everyone becoming infected by a virus in the wild. With a safe and effective vaccine, you can end it way before that.
