Preliminary Analysis of Association Between mRNA Vaccines And Sudden Hearing Loss

▫️In A New Study, Johns Hopkins Medicine Researchers Have Tried To Address Recent Reports That Sudden Sensorineural Hearing Loss - A Condition That Occurs As A Result of Damage To The Inner Ear - Has Been Suspected of Being A Potential Side Effect of Vaccination Against SARS-CoV-2, The Virus That Causes Covid-19.
▫️Out of More Than 86.5 Million Vaccine doses Administered During The Study Period, The Researchers Identified 40 Cases of Sensorineural Hearing Loss (SSNHL) That Appeared "Most Likely" To Be Linked To Vaccination Because They Had A Temporal Association, Occurring Within Three Weeks of Receipt of SARS-CoV-2 mRNA Vaccines, and were reported and documented by a healthcare clinician.
▫️Because VAERS Data Is Unverified, The Authors Performed A Sensitivity Analysis And Came Up With A Minimum Incidence Rate of 0.3 Per 100,000 Per Year, And A Maximum Incidence of 4.1 Per 100,000 Per Year.
- That Is Still Lower Than The Known Population Incidence of SSNHL, Which Ranges from Roughly 11 To 77 Per 100,000 Depending on Age Group, They Note In JAMA Otolaryngology-Head & Neck Surgery.
