Pfizer Effectivity against Delta (General)
Another thing coming out in the media that bugs the shit out of me is that the experts are saying, over and over, that the unvaccinated serve as a breading ground for new variants.
In the same breath, they're admitting that the vaccinated carry as much of a viral load of the Delta strain as the vaccinated.
If they carry the same viral load, they're spreading it equally. Furthermore, it is those who are vaccinated who are truly training the virus to mutate to beat the vaccine.
So in fact, with regards to the Delta variant, it seems that it's the vaccinated who are providing a prime environment for a deadlier strain to emerge.
