I had an ICU nurse friend and before the pandemic they were already being required to have a flu shot. She hated it b/c she would always get the flu- so she was sly.. she would go to her annual physical and the doctor would ask about her flu shot and she would say oh she already got it at CVS or Walgreens or whatever and he would say ok and mark her records! I thought this was brilliant b/c now her official medical records are marked as having been vaxxed. Where there’s a will there’s a way..
