Fcuk me you're impossible and I knew you were going to bring that up.
It must have been said about a million times to you, none of the vaccines are 100% effective, that has never been claimed.
So if they're not 100% effective there's still going to be breakthrough cases and unfortunately some deaths.

You haven't had the vaccine, give yourself a pat on the back for being a proper man. ?
