96% of practicing physicians are fully vaccinated [1]. That number goes way down as you look at nursing home aids, nurses, and home aids. If the argument is that healthcare workers not taking it makes it rational and reasonable, you need to contend with the fact that the more educated you are in medicine, the less hesitant you are.

It seems more likely that nurses and aids can't interprete dense medicalese or understand mRNA any better than the average person and are no less susceptible to misinformation than the average person. That doesn't make them incompetent at their jobs, which aren't about creating complex treatment plans using the latest and greatest medical research, but finding veins, delivering meds, scrubbing sores, changing bed pans etc.
