I live in a super liberal, high hysteria area...Admittedly, I wore a mask for a long while but as soon as the CDC changed their mask recommendations I haven't donned a mask. At least 50x since I shed the chin diaper I have been asked "Did you get your vaxx?" "are you vaxx'd"? "did you get your second shot?" etc.
Each time I answer the question truthfully (One person did ask me what type of vaxx I got to which I answered: "J&J I think"). Since I have been "fully vaccinated" since the 70's, and some of those tried and true vaccines were administered in a 2 shot series I am telling them the whole truth and nothing but.
Most people are dumb as rocks and don't ask questions that will return the answer they seek. Use their stupidity to your advantage.

If they ever ask "if I'm vaccinated" I answer truthfully as "Yes," considering I got all my shots as a kid. We have more important hills to die on than taking the bait of a yes or no question from literal nobodies.
