Sounds reasonable, frankly. The one thing that might really piss Putin off, of course, would be the 2014 Maidan Revolution, but by 2022, Ukraine would have already been way too strong for any punitive Russian military expedition to really effectively work. Still, getting used to the fact that Ukraine is permanently lost for him and Russia is likely to be very difficult for Putin.
As for the 2012 West, supporting Ukraine to 2022 levels will come as a shock to them, no doubt, but if Russia will refuse to withdraw its troops from Ukraine, then the West will probably morally have no choice but to militarily support Ukraine to the max bar direct Western military intervention.
COVID-19 is likely to be quite a shock once it spreads from Ukraine to the rest of the world in 2012 in this TL.
Does Ukraine itself already have many vaccine doses for it? Enough to share with the rest of the world?
