Vaccine hesitation.

I always come back to this chart whenever I want to remind myself that people's views on vaccines are quite fluid.

Also a good reminder of how high vaccine hesitancy was in fall 2020 when Trump was trying to bypass the safety trials.

If you extended this into 2021 and 2022 you'd find what moved a lot of the vaccine hesitant was talking to their vaccinated friends and family or family doctors. So don't be shy about being vaccinated to those close to you. You're often more influential than any other source- precisely because of your relationship to that person.
