So "protecting the vaxxed from the unvaxxed" has it backwards. The vaxxed, because of more asymptomatic carriers, puts the unvaxxed (and other vaxxed!) at risk of exposure to the WuFlu. Without immunity, more people will come down with the disease. Without suppression from re-transmission, more people will become exposed. As for recovery, all the vax suggests (NOT promises) is that you might have fewer symptoms and an improved outcome.
People with the vax can still die.
I wish Biden were back in his coherant years, say 30 or 40, and could look at his own statement here and see how utterly stupid it sounds. Was there ever a time in his life he could be embarrassed? Maybe a 30 year old Biden would never have said this.
