The most hardcore vaccine resisters tend to be older, white, and Republican

Roughly half of the people in the most persuadable group are Black or Hispanic, whereas the most resistant group is overwhelmingly white. The dug-in opponents also identify more solidly as Republican, and are disproportionately concentrated in the South.

Between the lines: Two additional themes unite those most resistant to being vaccinated.

They’re most likely to say they don’t consume traditional mainstream news, and they’re most likely to distrust authority figures or institutions, including the Centers for Disease Control and Prevention, President Biden and state governments.
