As a counterpoint, Portugal currently has 81.10% fully vaccinated and 86.85% vaccinated once (meaning they'll be vaccinated again in 4 weeks or earlier), and the new infections are going down slowly but continuously for a while now.
My point is not that you're wrong, but that you were cherry picking examples and there can be numerous other reasons for spikes in infections such as relaxed measures and mask mandates, holiday season, schools re-opening, etc. It requires a more careful analysis than yours.
Yes, lock down and social isolation does work to prevent transmission but it also weakens the healthy immune systems and makes the population more fragile going forward.
Better to inoculate the most vulnerable, not the entire population for a fast mutating respiratory virus.
Polio can't really mutate and it makes a lot of sense to inoculate everyone for this.
