We met unvaccinated, when the rules allowed. It's the non disclosure part I feel a little uncomfortable with, but I guess she is within her right not too tell you. That's clearly a boundary she has set and you are free to set yours too, be that to continue or not. But yeah, I get where you are coming from in that she could just tell you, would help you to make your mind up! End of they day though, vaccinated or not you can still carry and pass on the virus...
