I don’t know if they do it, because no independent researchers examine those swabs, but I have always pointed out that our overlords seem more concerned with testing than with vaccinating. Almost like the vaccines were the bait and tests were the switch. And now we also know they totally CAN do
Just follow the science below.
Scientific research paper excerpt:
Methods: Intranasal administration is a non-invasive metod of drug delivery that may bypass the BBB [blood brain barrier], allowing therapeutic substances direct access to the brain. However, intranasal administration produces quite low drug concentrations in the brain due to limited nasal mucosal permeability and the harsh nasal cavity environment. Pre-clinical studies using encapsulation of drugs in nanoparticulate systems improved the nose to brain targeting and bioavailability in brain. However, the toxic effects of nanoparticles int he brain are unknown.
