I appreciate this post and the effort that went into it. Thank you.
What I'm wrestling with is in the bold paragraph. We are never going to achieve 100% vaccine rate. That will just never happen, simple as that. It's an unachievable goal. So if there are going to always be those who are unvaccinated, and variants will always spread through them, and the vaccine cannot protect against these variants, when does it all end? What is the timeframe? Two weeks to flatten the curve so hospitals don't get overwhelmed? Herd immunity that can never exist due to variants? If we cannot take our masks off now, then why? The only honest answer appears to be never, which is an answer I simply refuse to accept.
I agree that 100% is not a reasonable goal. Good thing no one in the scientific community has ever said that. The actual number to aim for is around 77%, and that's definitely more achievable. Hell, if you look again at those age group breakdowns, some of them are already there, or at least pretty close.
Now, that 77% is for the entire population, which leaves us with a problem. Specifically, a sizeable chunk of it (0-12) is currently not eligible for the vaccine. That means in order to get to that 77%, the age breakdown looks something like this:
0-11: 0 %
12-17: 85 %
18-59: 85 %
60+: 90 %
total: 77%
And thus you see the problem. Those younger age groups especially are nowhere close to where they need to be, while the oldest age group....actually is pretty close. Again, those statements we've heard all pandemic long about how "if you're young it won't really effect you" and other nonsense is returning to bite us again and again.
My honest answer is that there are two realistic options to get to that magic percentage. The first is to get that youngest group vaccine-eligible, and do a massive vaccine drive through schools to raise the numbers in those bottom two groups. Using the carrot of "if we can get the school vaccine rate high enough we won't have to mask during class" would go a long way here, and I can attest from personal experience of working at a school that many students really do want to get the vaccine (we ended up with a majority of our juniors and seniors vaccinated as soon as they were eligible, with our freshmen and sophomores joining them). Now, this does mean waiting a bit for the vaccine to clear clinical trials, which take longer with children because their bodies are developing and thus react to things differently, but to me this seems like a major opportunity point, and even in general raising the 12-17 and 18-24 rates should be a major emphasis point for government at all levels.
The second option, probably more controversial to people here, is to make life miserable for people who refuse to get the vaccine. This would involve things like vaccine passports and mandatory checks, but the idea is to create an atmosphere that incentivizes getting a vaccine. Want to go to Disneyland? Better have your vaccine passport handy. Want to go on a trip? You're not going anywhere without a vaccine. Want to eat at a restaurant without having to worry about a mask? If you can't show proof of your vaccine, then sorry, looks like you're out of luck. This extends to businesses as well, who should be incentivizing getting their employees the vaccine (as an example, I went to the Flame Broiler by my apartment, and they had a sign explaining that everyone working in the restaurant was fully vaccinated and thus wasn't wearing a mask).
In either scenario, there has to be an understanding that this is a huge ask, and unfortunately we live in a world where, as I've said, a sizeable chunk of the population has decided that they will refuse to get a simple vaccine simply because they don't agree with the political affiliation of people in charge. It's meant that the US, which has had access to larger quantities of the vaccine than anyone else, is now lagging behind on vaccination rates compared to other major world powers. And let me be perfectly clear: neither political party is blameless here. Republican officials are at fault for continually giving in to the loudest and stupidest part of their base, and Democratic officials are at fault for trying to have their cake and eat it instead of doing the right thing.
That's, unfortunately, where we're at. We're on a treadmill, and every time it looks like we're about to reach the end of the set, we start standing on the sides and congratulating ourselves, and end up extending our time on the treadmill even further. Eventually, we will get off it, but it would require the collective of Americans to get over themselves and act for the common good for the first time since World War II.
