The real "holy grail" is and has always been a healthy immune system, one which doesn't need these latest "holy grail" injections. The later are products, and products require marketing, as even the vocabulary of the last mRNA "event" marketing proved with the lingo, "uptake" and attack against those rejecting the marketing, "hesitancy."
Marketing wants sales, uptake and even allegiance, while "caveat emptor" is still very sound advice indeed.
Great comment.
