Unsprayed weeds don't become immune to Glyphosate.
Ugh, well?
It's actually a problem. That mirrors the covid in a way.
Point being that the only way a virus could adapt to be immune to a vaccine is by being exposed to the vaccine. The vax-resistant variants aren't coming from the unvaxxed.
That's not true. The mutations are random. A resistant host doesn't create mutations, a resistant host might select for them , but not create, If the two strains had the same profile for viral load/communicability etc it might require a vaccinated population to select for the mutated strains, but in the case of the Delta variant its just more transmissible, it would have spread even without a vaccinated population.
As for Delta it was first identified in India at a time when the vaccination % was quite low. its possible that it originated in a vaccinated host but not that likely.
