Title is question, but to clarify my assumptions:

• Vaccination is a numbers game, and the odds are in your favor that the vaccination will protect you over you get a side effect or an allergic reaction/shock
• An infection like covid/flue can damage your body long term, not even speaking of long covid etc.
• To the best of my knowledge it has been shown that flue shoots lower the risk of dementia later in life, wouldn’t it be a good enough guess that a covid shoot decreases risks for this too
• Even if we only assume a covid vaccination is highly to reduce your sick days for only this year, isn’t it a rationale tradeoff to get vaccinated, just to avoid 1-2 weeks sick?
• Given the security of covid vaccinations, I feel like they have been scrutinized and tested extremely well and to the best of my knowledge it was checked that nothing of the vaccination remains in the body after a few weeks (for the argument that nobody knows the long term effects of RNA vaccination)

Again my question: Why doesn’t the WHO or don’t most countries recommend covid vaccinations for everyone? Are there any health/medical reasons? Are there financial reasons? Are there any countries/governments which recommend the covid vaccination for everyone and not only the ‘vulnerable groups’?

Edit: Just to add, I am living in Germany and right now we have a big wave of children flue, where children even die in the hospitals and the children hospitals are near their limits. It seems common sense to just put flue/covid vaccination into every child/adult, to avoid situations like this.
