The point is that it is not really a vaccine. A vaccine is against a specific threat, like this or that virus, and if it is good, against this or that virus class.
This stuff works by keeping your immune system on a hightened alert status, so it can react faster to any incoming, known threat. The known part is important here.
And if this “keeping the immune system on a permanent alert status” was any good on the long run, nature would long have normalized this, so there must be a severe drawback to it.
I read somewhere that when default body temperature was defined (100+ years ago), it was half a degree higher than nowadays, with all the hand washing, vaccines, etc. So maybe high alert used to be the norm.
