The study appears in the popular journal, Nature. We urge readers to exercise extreme caution over nasal swabbing. The practice offers no added benefit, but does present higher risk of harm.
This compelling peer-reviewed study from the prestigious international science journal will add to concerns that PCR nasal swabs (nasopharyngeal swab) are unsafe, while other evidence shown below proves nasal swabs offer no extra value in COVID19 virus testing.
Key cause of concern is that the intrusive long swabs make contact with the delicate cellular barrier at the top of the nasal passage in close proximity to the brain. This is precisely the site which may be compromised by metal nanoparticles referred to in the Dublin study.
When these nanoparticles enter the brain their cellular messengers are released and may cause damage to the DNA of developing brain cells.
