How do vaccines work? They expose your body to a virus in a harmless way. Your body fills with rage at the invader and produces antibodies to kill it dead. If you ever encounter that virus again, well, your body knows how to deal with lowlifes like that. Whap! Smack! Pow! No more viral scumbags.
How do vaccinations work on a population when not all of the population receives them? The more people you inoculate, the harder it is for the virus to find new victims. It can't land on a person with antibodies, infect him, flourish and then leap onto someone else like a panther jumping down onto an unsuspecting diversity consultant taking an eco-tour in the jungles of Guatemala to learn how horribly sinful America is because of
I seem to have wandered off point. Anywho, it works because it eliminates lots of vectors for transmission. The more antibodyful people you have, the slower the virus spread becomes.
Now dig this.
That's data for a single county in the US, but all of the data from around the world looks the same. Regardless of underlying conditions, if you're under 50, you're fine. That means we already have a vaccine.
Vaccine: Let everyone under 50 do whatever they want. You want as many of them as possible to contract the disease and develop antibodies. The only trick is to keep them away from the vulnerable people while they're contagious. That's it. That's the only way out of this.
Watching Bad TV - Wheel of Fortune and Jeopardy! - the ads are full of "we must all obey our leaders and remain locked in our homes until this is over." It drives me batty. Staying in our homes is how to prolong this thing.
The only way out is through.
