Pfizer makes a point of saying its mixture of lipid nanoparticles and mRNA is “preservative-free.” That’s because a preservative that’s been used in other vaccines, thimerosal (which contains mercury and is there to kill any bacteria that might contaminate a vial), has been at the center of worries around over whether vaccines cause autism. The US Centers for Disease Control says thimerosal is safe; despite that, its use is being phased out. There is no thimerosal—or any other preservative—in the Pfizer vaccine. No microchips, either.
Is the microchips add-in comment MIT's attempt at being cutesy while informing the rubes about the "science"?
Why not go all-in and tell us there are no nanobots in the ingredients!
I agree - MIT is being a bit cute/mocking in this piece. That is why the mystery nucleosides mention strikes me. Did they miss the talking point that said “Don’t talk about the modifications to the RNA?”
