Yes, disabling of innate immunity (natural antibodies and natural killer cells) is the prediction made by vanden Bossche, and the southern US + Israel summer wave being so much larger than last year supports his prediction (in other places, the spring 2020 wave messes up a comparison between summers). Either delta really is "super contagious" (pfft) or our immune systems are degrading in real time from stress, or we have turned off the "immune dark matter" that was so prevalent before the vaccines. I made a clunky chart of the concept - https://unglossed.substack.com/p/forever-spike#footnote-anchor-15
