This is my answer now when people of authority over me are asking if I have had my vaccine yet.
I tell them I'm in the control group that is not taking it.
I tell them that If I die from COVID, it means I probably should have got the vaccine. If they die, it means they shouldn't have, and at least now there is a way to know the bottom-line effectiveness of the vaccine...
I've found this gives them pause and sounds just medical enough to confuse their tiny sheep mind. I also say it with a certain degree of certainty and relief in my voice, just to keep them thinking.
My husband's Scottish ancestor (1780's) wrote an autobiography on his death-bed, which we received from my father-in-law. In it, the ancestor described that at the age of ten, he ran away and hid in his trout-fishing spot, when the experimenters came to his house to vaccinate against smallpox. He had seen some people in the village die from the procedure, and he would not have a bar of it.
