T1 Preliminary Analysis of Association Between COVID-19 Vaccination and Sudden Hearing Loss Using US Centers for Disease Control and Prevention Vaccine Adverse Events Reporting System Data JF JAMA Otolaryngology–Head & Neck Surgery JO JAMA Otolaryngol Head Neck Surg YR 2021 DO 10.1001/jamaoto.2021.0869 VO 147 IS 7 SP 674 OP 676 SN 2168-6181 AB Many vaccine-related adverse events are associated with otolaryngologic manifestations. In particular, the incidence of sudden sensorineural hearing loss (SSNHL) was examined after influenza vaccination in a large-scale study that demonstrated no association between vaccination and the rate of SSNHL. Anecdotal reports are rapidly emerging from the otolaryngology community of SSNHL occurring after inoculation by SARS-CoV-2 vaccines that are currently in use in the US under US Food and Drug Administration Emergency Use Authorizations. Recognizing the important public health implications of any association between COVID-19 vaccination and SSNHL, and motivated by patients who presented to our practice (Johns Hopkins University; Baltimore, Maryland) with audiometrically confirmed unilateral SSNHL that occurred within 24 hours of COVID-19 vaccination, we sought to (1) estimate the national incidence of SSNHL after COVID-19 vaccination using data from the Vaccine Adverse Events Reporting System (VAERS) maintained by the US Centers for Disease Control and Prevention (CDC) and (2) compare this with the expected incidence of SSNHL in the wider population.
