I have no idea but I have read scientists blame the variants on the unvaxed before today. It must be a CDC talking point to guilt trip us into getting jabbed. All I see are the vexed spreading it to each other.
Sad when an otherwise good doctor spouts talking points of those who wish us dead. Judging from my own doctors it seems they are controlled like the media to say and do as the cabal wishes. My oncologist is so into the “wear a mask or die” idea regardless of blood counts being very good. I want to say “think!” but I smile and move on.
