The same as if I found someone with the shot spread the flu. Or if the visitors came with the flu. Or i found out masks were not used by staff during the outbreak. Or I could go on because there is no way to know which person the shot works with and which it doesn't. If we had 100% take on the shots and it is 90% (a couple seasons ago it was 30%) effective we still have 50ish potential hosts out there. The take rate for residents is as close to 100% as it gets. So, either the flu shots work and we don't have to take extra precautions (they don't) or they don't work and we should be doing what we can to protect them (we don't).

I completely understand the reasoning behind it, it is just flawed reasoning.
