Here's how rough the standards are. There is no "green" tier for return to normal life. It's purple/red/orange/yellow. To get yellow you need to get less than 1 case per 100,000. So LA County would need to report less than 90 cases per day. LA County reported 1,604 cases yesterday.
It also means unless the vaccine is about 90-93% effective or above and compliance is somewhere in the neighborhood of 85-95% in taking the vaccine, or unless the thing somehow herd immunities and magically disappears (very unlikely) we are looking at restrictions FOR YEARS into the future.
