This is a kindof off-vaccine-related comment, but what the hell, this whole thread's been derailed, I haven't read most of it, and it's bound to be locked any day now when someone shows up and starts spewing shinyhappy stuff...
As a society, we've been advancing towards more and more people living in cities or dense suburban areas. And on top of that, even more people are all packing into trains, buses, and cars to drive into large urban areas for work. Or 1000 student schools/ colleges. All this is doing is creating a society where diseases like this are going to be more and more likely to ravage populations. COVID has a survivability rate of around 99%, but is highly transmissible. What happens when some virus happens to commingle high fatality rates along with high transmissibility?
I've been working from home since, no E36 M3, March. Since then I've had to go into an office/ shop at work maybe two or three days out of every month. I've been busier than fire ants in South Carolina during mid-August, too. Many of my friends have relayed similar accounts. Interestingly, there seems to be a wide variation in what corporate plans are going forward- some, like Amazon, have said they intend to go back to a more traditional office setting. Others, like many of the places my friends work for, have said they'll be cutting office space leases by 75-90%.
Long term, do we keep piling into higher density living/ working situations and hope that our immune systems can keep up, or do we start to back off and decentralize? I read somewhere that if we evenly distributed the population of this country, every man, woman, and child would have like 7 acres of land. Obviously that's unrealistic, but it hints at just how huge this country is and how questionable it might be to cram millions of people into areas of a few square miles- if the technology to permit people to live/ work remotely becomes environmentally and economically viable. Obviously, a brick layer and a surgeon can't work remotely, but an engineer can work at least partly remotely, and an accountant or a writer can be almost completely remote. Listen to the radio lately- eventually you'll hear the DJ mention they're broadcasting from their basement or garage.
As for social situations...as much as I love a good meal out, or a few drinks at the pub, perhaps we don't need hundreds of restaurants and bars in every city. Maybe we eat and drink at home more? Spend more time with our families, and less with strangers? Maybe we create stronger bonds with a few people, and not casual relationships with dozens?
