No, nobody lied. The vaccine phase 3 trials showed very good effectiveness. Real-world effectiveness was lower due to:
- Immunity fading over time
- The virus mutating
In late 2020, we knew these were possible, but not whether they'd manifest themselves. If we wanted to see before releasing the vaccine, it would've been years. I suspect another factor in declining vaccine effectiveness is that by now, almost everyone has either had the vaccine or the virus, meaning additional doses are boosting immunity more than creating it anew.
Oh plenty of people lied about that. Well, they expressed their opinion about it, and that opinion was incorrect. But mostly on television and in newspapers, which is where most people hear about it. Because of this, it has been the dominant message most people received, even though contradictory claims are easy to find.
Lies are never fully black and white, they're never 100% false. That's way too crude and ineffective. Any good lie has to overlap with the truth, or even best lie by omission. The WHO withheld from calling COVID airborne until very recently. And that change basically went unnoticed, because it wasn't repeated in opinion pages, front pages and TV reports the same way the hopium-based messages, seemingly inspired by some belief that fear of the virus is worse than the virus, have been.
This is how modern propaganda works. It's never full Orwellian lies that bury the truth entirely and hit people on the head for saying otherwise. Rather it's through the dissemination of more lies than truth, with lots of overlap that deliberately confuse people over whether there is any knowable truth. Public health is treated as a political strategy, and so shares a lot with the usual ways of politics. Including the lack of any accountability.
Turns out that unless there are indisputable mathematical equations showing a definite proof, truth is mostly a relative concept, a matter of perspective, even in scientific disciplines.
The recent messaging has instead been turned into a matter of personal responsibility, even though it's completely impractical and condemns many. It has some truths to it, it has many lies to it. People can get vaccinated, but they were told the pandemic is over so they mostly don't. And the vaccines have limited efficacy anyway. And they can get treated if they get very ill, as if it's a small matter to get so ill one has to go to a hospital.
Everyone is just winging it, doing whatever they can manage to succeed in their immediate social environment. All of this is just too complicated for our tiny human brains, we are completely out of our depths for the most part. At this point I don't even think it's possible for humanity to survive without superintelligent AIs.
