[Question - other] Why do healthcare workers that are providing/administering the Covid-19 vaccine wear masks when doing so?

(Note: I am not a Covid-19 denier. I wear masks constantly, social distance whenever appropriate, and practice proper hygiene on a continuing basis through my day. This is simply an observation.)
