I recently noticed this too and put yes last week, but it is back again. Just did it 3 times but it is still saying to enter vaccination status. Ugh. Hopefully just a glitch
I have hit it a few times by ending my night in the casino sucking down vodka and cranberries. When the waitress says, "I am sorry, Mrs M, but you have hit your limit" it usually means it is time to go to bed.
