Our largest healthcare provider has already mandated vaccines for their staff and insurance companies are now following suit because they got hammered with life insurance payouts for 2020 and first half of 2021. Waiting for retailers to announce this as well at some point.
Seems reasonable to expect people working with many sick and vulnerable patients in a healthcare setting to be vaccinated. That’s one of the highest risk scenarios I can think of for exposure and transmission as well as the most likely place to concentrate vulnerable patients.
