Suppose I go to the hospital with a stubbed toe. They test me with PCR and the test detects fragments of dead inactive virus from a month ago when my immune system defeated it. I therefore test "positive" for COVID. They give me the vaccine, which promptly kills me from a combination of stroke, heart attack, and multiple organ failure. This would be recorded as a COVID death, and I would be considered "unvaccinated". Cheating like this is a big part of why the COVID death toll is as high as it is. It's fiction.
