The trouble is that there's this unfortunate tendency to try and deal with this by having different standards for what gets counted as a covid case depending on whether the person's vaccinated - either by testing vaccinated people less as suggested in that article or by interpreting the test results differently. Which makes all statistics about the proportion of people who catch Covid, are hospitalized with it, etc who are vaccinated complete and utter garbage - at that point you're not finding Covid cases amongst vaccinated people simply because you're not looking. It resulted in initial numbers out of Israel that seem to have wildly overstated vaccine effectiveness against current variants, and I suspect the same might be happening in the USA right now.
