You can have a strong and vocal anti-vaccine population and yet not have a strong divide on party lines. One factor is that not all countries have such a strong two party system that polarizes every single thing.

No, their single dose rate is already 10% higher than the US and increasing at a faster rate.

Do you have a link to the most recent data? I recall The Netherlands having some severe resistance to masks etc, but I haven't seen a breakdown of vaccine uptake by country in recent months.
