Then how come I am visiting all kinds of crowded venues since fully vaccinated on March 4th 2021, and nary a sniffle? Are you saying me every shopper in Winn-Dixie, Walmart, Costco, and dined in 7 restaurants in last 7 days (have daughter and her fiance visiting here in Florida from Seattle) had no one infected asymptomatic and exhaling covid-19 virus?
Your statement assumes the fallacy that simply being exposed to the virus means you’ll end up with it. I think even those early days when people were trapped on cruise ships and most were elderly, only a minority of the passengers contracted the virus.
