There's also content on herd immunity:
Seems a bit weak and sidesteps the main problem with herd immunity: it's based on lies, and the people suffering the consequences are not supported. It's an economic strategy, one that aims to keep full employment and, most of all, make sure the rich don't lose any money from it. In fact COVID led to the biggest transfer of wealth from the poor to the rich in history, so the rich really like it.
It would be one thing if the concept was "look, this will be bad, but having to weigh the pros and cons, the benefits of herd immunity outweigh the negative consequences, so we will pursue this strategy, but know that a lot of people will die, and a lot of people will be ill and become invalid, and they will be supported, at enormous costs that will be borne for at least a generation".
But this has never been the case, and we can't even know how bad it will be one way or another. Instead the public lie is that everything will be peachy, only people on their death bed, who are basically dead already, will suffer, and then elves and fairies will rise from the spring wells and lead everyone into a happy dance. Now the same "get infected people, get infected with viruses as many times as you can, they're good for you" is being applied to other pathogens, especially ones that don't cause massive acute illness, like measles and polio. This will happen, it's already baked in.
There are a lot of people who look smugly at how it went "well" with COVID, but if the upfront cost of 20-30M dead and 100M+ disabled, and all the costs associated with it, had been known, almost no one would have accepted it. It would have been considered monstrous. Even extremely low-ball estimates of 10K+ dead were dismissed as alarmist. But because it happened, in the distant past of just a few years ago, everything has been memory-holed, and because of that almost no one who needs help is getting what they need.
But of course since this is what happened, the next time will be the same. Governments will know that they don't even need to ask for forgiveness, because the only people who will demand it will be completely un-peopled, no one will listen anyway. Not even the medical professionals.
COVID was a gamble. Not everyone agrees that the price to pay was worth it, and for those who think it was, it's mainly because the main impacts they endured were the "lockdowns". But this is a psychopathic way of making such decisions, and it's completely dishonest. It dishonored the medical profession, which it turns will follow most monstrous orders that they are given, and completely de-fanged all the public health tools to deal with future pandemics. From this point on, there is only one politically viable strategy: gamble on the fact that it won't kill too many, and that the long-term impacts are mostly of the discriminated type that can be swept under the rug. Basically, the Fight Club calculation of whether the costs of doing something outweigh the costs of doing nothing, entirely ignoring the human impact.
If the next pandemic virus is one that can kill 30% of the population, this is how many people will die. It's almost guaranteed. And if it can in addition to that disable half the population, then so it will. Not making this clear is a terrible indictment of how such decisions are not made with consideration to life and health, but strictly about stock market performance and election cycles.
