i think those are sort of adjacent issues, but broadly, yes. there is a reason that every vaccine trial required symptomatic confirmation (or symptomatic presentation to even test at all) in addition to a PCR positive as a standard for a "case." not doing so in the broader public, especially when asymptomatic spread is so rare has never made much sense epidemiologically. over testing and poor use of tests that are not really fit for purpose (and extremely oversensitive) has led to outlandish overcounting and to high levels of false and false clinical positives. this has been diagnostic malpractice.
