evidence: Multiple Facebook (FB) posts published by the same netizen on Sept. 14 and which continued to circulate this month falsely claim that the COVID-19 nasal swab test is "dangerous" and could cause death. The swab inserted through the nose allegedly "damages" the endocrine glands and "breaks" the blood-brain barrier, allowing infections to reach the brain. [...] A group of public health researchers and scientists convened by international nonprofit organization Meedan said it is "virtually impossible" for a nasal swab to "access or have any impact" on the blood-brain barrier. "Rupturing the blood-brain barrier would require breaking through multiple layers of tissue, drilling through bone, and going through blood vessels, which is not possible with a nasal swab," they said in Meedan’s COVID-19 Expert Database website.
