Republicans are the largest vaccine hesitant group in the US and their hesitancy is not declining. What can we do about it?

In this new piece in the @LAtimes, I & @jayvanbavel discuss strategies and some of the relevant behavioral science in this space

latimes.com/opinion/story/…
We identify three broad approaches - general public health messages, promotion by trusted politicians, and promotion by trusted nonpolitical influencers – identifying behavioral science relevant to each.
We highlight @deaneckles and colleagues’ research on how vaccine intentions can be increased (in the US and beyond) by informing people about the actually very high levels of vaccination+vaccine intentions in the general public.

🚨New WP🚨 “Elite Party Cues Increase Vaccination Intentions among Republicans”

How to convince Republicans-biggest holdout group-to get vaccinated? We find pro-vax messaging from Trump+Rep elites works, whereas Biden+Dems message reduces enthusiasm

High vaccination rate is key for herd immunity. But vaccine intentions are deeply polarized. ~40% of Republicans report they won’t vaccinate, essentially the same % as in Nov. A flat line for 5 months! (while other groups - e.g. racial minorities - have shifted substantially)
In pre-reg'ed experiment (N = 1,480), we varied whether Republicans saw endorsements of the vaccine from Republican politicians (including video from Trump’s CIPAC speech), from Democrats (including a speech by President Biden), or a neutral control.
