Took one once, got sick as a dog.....never again. I'm not prone to getting the flu, so I takes my chances. However, in some of the hospital work I do, when in the break rooms for the nurses, on the bulletin board, they post a choice for all nurses in contact with patients: Get a shot or wear a mask.....your choice. In some of the ICU room, isolation protocols are in place, partly to protect the visitors, but most of the time it is to protect the patient. If they are in ICU, they undoubtedly have a weakened immune system and don't need anyone bringing anything in for them. If I have work in those rooms, I have to gown up, just like everyone else. Generally it's not urgent, or I imagine I would get the same treatment as the nursing staff.....shot or mask. I mask anyway if I go in. I don't what they have, for sure!
