I'm certainly no virologist but my understanding is that there is no such thing as a one-size-fits-all vaccine for this, at least not in the shorter term. But anything that reduces pressure on the health service has to be a good thing.
I think it will get to the point where people live with it and have their sick time, but the treatments will improve for those in more serious trouble, they already have since it broke earlier in the year. People will build up a tolerance and this idea of "herd immunity" over time but it will not be perfect. It seems that right now is too early for these things, and the Euro and US governments in particular can't have very light restrictions and hope it goes away, that's not a plan. This isn't going to disappear and might never, but years down the line the goal is for more susceptible people to take a vaccine a certain time of year like they might a flu or pneumonia jab.
