immunity against what? the next variant isn’t here yet to know
Ask the experts. They would know.
What are your credentials that you are qualified to challenge their assertion?
It is amazing that a species has lived this many millennia without mRNA technology and worldwide experiments to save us as a species, and a Mrs. Blueplum to tell that we don't know what we don't know.
Sciencey.
Last I'd checked the human species generates immunity to many disease agents and toxins without the assistance of the "state agenda" to inoculate everyone on the planet, because the WHO says we should not rely on what the species has relied on for millennia. Such a remark as this proves me to some a "pandemic huckster."
