When the vaccines were first introduced they were said to bring life back to normal by stopping covid spread making people immune.
At least that's the official line used in my country and from what I remember a general consensus.
Then when it came out it's rubbish, the uthorities changed the tune to 'they may not stop covid but make it milder'. And so it went on.
They even spouted some bollocks like you don't transmit it if you're jabbed or that the receiver will have it milder than getting from an unvaxxed.
I can honestly see the frustration from people getting confusing data every two months.
That's the problem though, it WAS true at the time, they had solid data that suggested being vaccinated decreased a lot your chances of getting infected or transmitting it if you were infected. It was true until the delta variant showed up and decreased this protection from 70+% to 35-45% (and probably less with omicron).
Also, as far as i've read in several countries, autorities didn't change their tune to "it makes it milder" since it always was the main effect of the vaccine, since the very first reports from Pfizer, it was the intended effect, the transmission protection was just a bonus that the autorities might have used for too long when it wasn't really true anymore (after delta). The fact that the symptoms are milder for vaccinated people is a VERY clearly and consistantly established effect, even with delta or omicron, there's tons of available data about that and it's pretty much identical everywhere in the world.
We see very clearly here that the authorities probably failed to inform you properlty, but you also failed to understand how it worked and when because this was all publicly accessible data and information.
Also, you can't having both way, you can't be "frustrated from getting confusing data every two months" and require accurate info from the authorities. Because it does change every 2 months or so, and if authorities want to be accurate, they will have to shift the lines every 2 months, that's just the way it is.
[Edit] : I've just read you posting history, it does seem that you are not even trying to understand, my bad.
