If one is widely distributed in time, and if it works. AND if the virus does not mutate enough to bypass it next year.
The way I see it we either find a working and safe vaccine and get it widely distributed, or it is basically the end of our civilization.
Because, if we are not able to make a working vaccine it is because there is also no such thing as herd immunity, which means this is never going to end.
This is not the end of mankind, just the end of the way our current civilization works. Densely populated cities are just no longer viable if there is something that is going to kill 2% of the population every year. Our social expectations will have to change to have a large percentage of our citizens unable to work for months at a time, and it looks like there are long term effects of this disease that we might have to learn to cope with. Hell, in the long run these changes might be good for us. Experts have been saying for a long time that our civilization is ripe for a disease to ravish us.
But change never comes easy. If we never stop this then it is going to get really ugly. We are looking at some major societally upheaval.
Members posting here are completely ignoring the costs of shutdown, and how it impacts us. There is a death toll there as well. There is a lot of pain and suffering and having to weigh it out because we lack the safety net we need to weather such storms. Americans need homes, and they need food, to the point of saying they'll risk COVID instead. Think about that.
No, because most of us don't think that full shutdowns are the best course of action. They were needed at the very beginning, and might be needed as spot treatments to bust particularly bad outbreaks, but we should have mostly gone past major shutdowns. It is mask wearing and social distancing, and actually convincing both workers and employers that it is their best interest to not encourage sick workers to come into public spaces. But currently half our leaders are treating this as a political issue and trying to create a wedge out of it. A large portion of Americans listen to those leaders, and don't take this thing seriously. They only wear masks when forced to, and then do everything they can to get around it.
Trump remains the symptom. He isn't our root problem.
It is often the symptoms that kill you. You have to treat them in order to have time to treat the cause.
