My company has a bona fide medical dept ( very large chemical co). There is a md, nurses, etc. About every three years we have a medical checkup. Give blood, check bp, hearing check. We were required to send our vaccine card to the medical dept via the Mychart app. If you’re not vaccinated you must continue to wear your mask etc. of course they loosened up the rules but recently tightened them up with the surge. So far it’s not a hard requirement but we’ll see what happens with the new mandates. I did get the vaccine so I uploaded it to my file. I also reported to the medical dept when I had COVID and had to be cleared to return.
