A compelling peer-reviewed study from the prestigious international science journal will add to concerns that PCR nasal swabs (nasopharyngeal swabs) are unsafe, while other evidence shown below proves nasal swabs offer no extra value in COVID-19 virus testing.

The 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 that 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.
