Win nobody said anything about capital letters making anything true. It just makes the statement more noticeable, for those who are visually impaired (or reading impaired?) But you knew that. You seem to be desperately fishing around for something that will keep the argument going.
Person #1: All the experts in this field are saying that the vaccine doesn't necessarily keep you from getting the disease. But it is obviously very effective in keeping you from dying of it. If you get the disease in spite of being vaccinated, it is likely to be more like a case of flu, or even milder than that.
Person #2: Oh, yeah? Well, I just read that (famous movie star, politician, scientist, etc.) was vaccinated, and they got it anyway!
Anything wrong with Person #2's logic?
