For sure, and I think this is incredibly important.
As I pointed out in that article, political identity has become.... Look, vaccination hesitancy is a very complex phenomenon. Access matters, needle phobia matters, past injustices matter. There are various culturally and socially complex phenomena.
Right now at the population level, you could argue that political identity has emerged as the single strongest variable of predicting vaccination hesitancy, and also the engagement with an embrace of vaccine misinformation. I think it's really important to highlight that history and context matter.
It hasn't always been like that. On the contrary, in the past, lots of the vaccine misinformation emanated a little bit from the left. It was kind of New Agey, right? It was whole foods and yoga and a distrust of anything that's not natural.
Now we see it very strongly on the right, and there is a large body of evidence to support what I'm saying. This isn't just me speculating. There's a lot of empirical evidence.
