We have the flu, it's not going away. Every year I get a flu shot. If I do get the flu (the shot won't always protect against that), there is every likelihood it will be relatively mild, and after a week or so of staying home, I can get back to living.
And yes, lots of people don't get the vaccine -- and some of them actually die. Nobody can help that, nobody is going to stop death from happening completely.
But if we shut the world down trying to stop this virus totally, then a lot of people are going to die of starvation and exposure, rather than the virus. I can't say I think that's a whole lot better, can you?
This virus is here to stay. Just like the flu. We simply must learn to live with it, just like we do with the flu.
