@Zardoz @BroDrillard Covid was constantly mutating from the "original strain." But Moderna's 2016-patented "gain of function" spike protein** did not change much, because it was very effective - so natural-selection preserved it, until the "vaccines" targeting it were released.

A good study showing this effect was a locked-down Vietnamese hospital, with gene-sequencing equipment on-hand, which documented how the variants among the newly-vaccinated hospital staff differed from the variants circulating in the general population. This also revealed the then-new vaxx did not "stop the spread."
