My conjecture is that people who are infected but asymptomatic due to vaccination would have no reason to show up in the case counts either way, since they would not seek out being tested at all. As for being a bold claim, it's established science that vaccination can not prevent infection. The virus can still enter your system. I agree that it is a debatable question as to how many and to what extent those vaccinated people are infectious to others.
