The numbers you're citing say that 19% of black and 30% of hispanic people surveyed don't plan to get vaccinated. The equivalent number is 24% for white people.

Moreover, empirical reality differs from polling. In New York City, for example (a big, liberal, multi-ethnic city), Latino people lag whites by 12% in vaccination rate; black people lag by 17%:

Whatever people are telling pollsters, it differs from their actions. Maybe they have "plans" to get vaccinated, but they're not doing it right now.

I didn't say not racial at all. I said more partisan. 45% of 1 major party. 7% of the other. Independents in between.

A different poll said Hispanic people are the most inclined to get vaccinated. But politics was the strongest correlation still.[1]

Cumulative vaccination rates reflect earlier hesitation. Also scheduling difficulties, transportation difficulties, and wanting to get vaccinated by a trusted provider.[2] But targeted efforts have closed or nearly closed the gaps in many places.[3]
