What the reader should take home from this is that neither vaccines are effective.  Neither will stop the pandemic spread.  Neither wil offer the herd immunity they've promised and insisted upon.  Not only have the powers that be redefined herd immunity to be that which only a vaccine can deliver, but the vaccines they promised can't do it.  Herd immunity, folks, happens when the herd has developed immunity naturally, and child-bearing mothers can pass it to their children.
