Covid vaccines : my theory of what will unfold next

Reading about the introduction of the "health pass" in Europe, it came to me suddenly that it always was the main purpose of this whole covid shitshow.
Basically, they want to condition the access to public venues to the green light of an health pass (stored in your electronic device of course), vaccination against covid-19 or a negative PCR test of less than 48 hours or a serological test which proves the presence of antibodies.

I believe covid-19 is the cover to force the economic and social changes required by the UN Agenda 2030, that the previous narrative, global warming/carbon footprint/peak resources was not convincing enough to bring about, and to mitigate the financial collapse that would have happened anyway.
The forced "third-worldization" of the West by a drastic reduction of economic activity and individual freedom, a sort of WW3 that transforms the system and removes the useless eaters while keeping the infrastructure intact. With that in mind, here's how I see the system narrative unfold from here.

They will keep vaccinating the gullible like crazy. Cases will go down, as spring comes obviously. But to MSM it will be the result of this unprecedented vaccination campaign. As they chant 24/7 the miracles of big pharma and how the super cool health pass works, restrictions will gradually be lifted, and the health pass will become a permanent feature in most people daily lives, that they'll carry around on their smartphones. All will be done progressively, as always. First it will be only required for international travel and large gatherings, like sports events and concerts. Then in all public transportation, museums, restaurants and non-essential shops. Of course, many will decide to check out from this dystopian world, which will further decrease economic activity.

But what about the vaccination itself? Like the flu shots coming in a new flavor every year, you'll have to get regularly injected for the new variants, probably twice a year. Maybe at some point the tests won't be allowed anymore, only the vaccines.
These injections will allow TPTB to cull and sterilize the population they consider now unneeded. I believe it will happen slowly in many different ways that won't easily lead back to the vaccines as being the cause: cancers, heart attacks, autoimmune diseases, and all sorts of sudden and inexplicable deaths and miscarriages, as we have seen a lot happen already.
I don't see millions of people dying at once like some here. The risk is too high for TPTB to lose control of the narrative. Even for them, you don't want to wake up billions of people from their slumber. It's better to do things stealthily, while their system is getting back up again, their MSM keeping the lid on the people dying, with everything back to normal for anyone submitting to the health pass...

If the MSM could cause people to panic when nothing was happening, they can as well keep them quiet when people are actually dying in droves...

So what do you think of this scenario?

Before you raise the BS flags, I have to admit that it's the theory of someone who lives in a de facto communist country and has worked a few years for the European institutions lol
These people are THAT delusional and I tried to think like them. Maybe you living in America will consider the above totally unfeasible ha ha
