It doesn't think much to out-perform the Western/EU countries. Even countries like Slovenia and Malta are doing better than the NL, France, Belgium or Germany.
The problem is simple: they banked it all on the AZ vaccine. AZ had major supply issues which caused a major delay back in January. Now 3/4 months further AZ is off the market for most groups because of the blood cloths, vaccination willingness is hitting an all time low and people are closed to being depressed and can't comply with measures anymore.
But in fairness I don't see the situation getting better at all in the coming years over here. We might get a good dose of Biontechs and Moderna vaccines but considering how the virus is developing internationally it'll be only a matter of time 'till we see outbreaks of SA and Brazilian-variants which the vaccines don't seem to work against.
It's pretty much what @swag claimed a few months ago. Vaccines or no vaccines, this virus is here to stay with all its future variants.
