New Covid Protocol - Vax or Neg Test required “Cases” is such a broad term. I assume it includes people who tested positive but had no symptoms. The delta virus replicates faster than your vaccine immunity can respond. So you can be positive for a few days, then your immune system kicks in, and you are protected. Several studies suggest vaccine immunity is stronger than natural immunity. Ive seen others that suggest the opposite. Like 72 said, you can use stats and various studies to prove your point, regardless of what side of the fence you are on. I personally find the precautions taken to go into an Aggie football game as reasonable, and I feel safer there than at Walmart :).
