Many people who have gotten the vax are Mr Smith all the time. I see it in the questions at work when discussing work policies. They'll ask questions in the form of statements like "why are the unvaxed being rewarded and allowed to...?"

Also questions like "Can we find out who the unvaxed are so we can avoid contact with them?"

"Doesn't having unvaxed people at work threaten the health and safety of the rest of us?"

Now that I think of it, we might have several CIA plants in the plant.
