When the vaxxes were first rolled out, there were several doctors warning about vaccine escape, that it violated standard protocol of never i vaccinating during an epidemic as it did just what we see here, fuel variants.
The effect of environmental selection pressures of evolution are covered in every college level introductory biology course. These people are at the CDC sat through the same classes as I did. They can’t claim ignorance.
