Hyperbole aside, in an emerging pandemic with rapidly changing variables, it's understandable why guidance and recommendations do change. People act like health professionals should have perfect information, but that's just not how things work in the real world.
Nothing has changed from my view of the situation 'way back in February 2020. There were certain things I realized then that are still true now.
1.
Everyone would need to wear effective masks in order to function within the contagion. I had a few N-95 masks already available because I'm an avid DIY-er, but I immediately found sources of KN-95 masks and even laid in a supply of HEPA filter material in case we'd wind up making our own masks (I did say that I DIY).
2. I understood from the beginning that transmission mitigation techniques (quarantine, social distancing, masking, hand hygiene) would be necessary until an effective and safe vaccine (and I based "effective and safe" on bars set by past vaccine development) was developed at least 80% of the population was vaccinated. In February 2020, I expected that not to happen until early 2022. Actually, I expected the vaccine not to be available until 3rd or 4th quarter of 2021, and that people would willingly accept the vaccine so that the vaccination program would take six months. I didn't expect the vaccine to be developed as fast and its acceptance to be so slow. But all in all, we are about where I expected us to be at this point, but for much stupider reasons.
3. I understood from the beginning that "herd immunity" depended on vaccination...I said more than a year ago, "humanity has never died its way to herd immunity to any disease." I also understood that no vaccine is 100% safe for 100% of people, nor is it effective 100% of the time against 100% of the virus, and that over time mutations would occur requiring updated vaccinations. This was all easily available information all along.
There are several things the government did wrong, a couple of them Fauci himself did wrong:
1. The government depended on stockpiles rather than industry. This is actually an unintended consequences of the military-industrial complex. Prior to WWII, the concept was to set the stockpile for the period of time it would take American industry to convert to wartime production...from producing automobile to producing tanks. The advantage to that was flexibility...the Army would not be facing a new war with a great stockpile of the last war's weapons. It also has the advantage of not actually spending money beforehand.
But the "stockpile mentality"--an outgrowth of the military-industrial complex--was the concept of deciding beforehand what the new war would look like and attepting to stockpile for it. The problem is that nobody's predictions are that accurate. The new war is never what you predict it to be, and nobody ever wants to spend enough money on a stockpile.
So what happened in this case is that the government went cheap on the stockpile of PPE. In order to go cheap and still claim to have met the requirement, they simply predicted a situation where any outbreak would be something we already had a vaccine for and would outbreak in only a very isolated fashion. (That was, of course, the ultimate of stupidity considering that a deliberate strategic biological attack was always a real possibility.) So the nation ended up with a paltry stockpile and no concept of industry ramping up to meet a new need.
By "ramp up" I'm talking about whole segments of industry converting from one product to another, building new production spaces, et cetera, and government having a plan to make that happen efficiently. For instance, the government would have determined what kinds of industries would participate (such as all the various filter manufacturers), how 3M's patent on N-95 filters would be licensed to new alternative manufacturers, how quickly the alternative manufacturers would go into production, et cetera. The government has done this kind of thing before.
Fauci made a critical error in judgment in denying that masking was necessary for everyone (I never believed that for a moment--I've had biological warfare training). Trying to solve the PPE shortfall was not his call. He should have told the truth and given that problem to government and industry to solve. Instead, by denying the need for masks, he also denied any reason for industry ramp up to meet it, or for government to authorize, encourage, or plan for it.
He also played far too coy with the extent of the shut-down that was needed. Fauci led the nation to believe that the goal was to "flatten the curve," and we would all be in the clear. That was never true, "flatten the curve" was only a "first down," not a goal. He kept saying, "...another two weeks." Again, he was trying to solve the medical community's problem rather than telling the whole truth and letting other elements of the government solve the problem. The social shutdown should have only been as long as necessary for industry to ramp up PPE production so that business could function again
within the contagion. But he had already killed the rationale for an industry ramp up, and he muddied the water for the change of advice that was clearly inevitable.
Fauci knew all the time the same thing I knew, or that anyone with biological warfare training would know: Operation cannot shut down for as long as it would take to implement vaccination. Ultimately, Fauci did not give national decisionmakers the full and complete information they needed to have.
