Post Vaccinal Temporary Sensorineural Hearing Loss

Abstract

In our systematic research we identified four studies concerning the onset of neurological adverse events following vaccination and two excluding this association. A 33-year-old Italian man, belonging to the Italian Army was hospitalized because he suffered from vertigo, nausea and sudden right hearing loss not classified (NDD), that set in 24 h after the administration of tetanus-diphtheria and meningococcal vaccines. Some neurological events arising after vaccination are very difficult to treat. In our case, the functional recovery on low and medium frequencies was possible about 6 months after the morbid event.

Sudden sensorineural hearing loss after COVID-19 vaccination

“…Several cases of SSNHL after vaccination have been reported, including after influenza vaccination (Huang et al, 2010, Baxter et al, 2016, Kolarov et al, 2019, tetanus and diphtheria vaccination as well as meningococcal polysaccharide vaccination (De Marco et al, 2018), and rabies vaccination (Güçlü andDereköy, 2013, Okhovat et al, 2015). The etiology of SSNHL after vaccination is unknown (De Marco et al, 2018).…”

The etiology of SSNHL after vaccination is unknown (De Marco et al, 2018). In Baxter et al's large-scale study, there were no associations between SSNHL and previous vaccination, including trivalent inactivated influenza vaccine and others (Baxter et al, 2016, Formeister et al, 2021.…”

“…Sudden sensorineural hearing loss (SSNHL) is defined as hearing loss ≥30 dB over three consecutive frequencies within three days (Okhovat et al, 2015, Chandrasekhar et al, 2019, Kolarov et al, 2019. The etiology of SSNHL usually is idiopathic, but it can be attributed to viral infection, vasculitis, autoimmune disease, and tumor (Baxter et al, 2016, De Marco et al, 2018, Chandrasekhar et al, 2019. We report three patients with SSNHL within three days after COVID-19 vaccination and consider an association between them.…”

Drug‐induced hearing loss: a case/non‐case study in the French pharmacovigilance database

“…Concerning vaccination, data in the literature are controversial. Several cases have been published, particularly regarding meningitis, tetanus and diphtheria vaccines , hepatitis B vaccine with complete recovery after 6 months , flu vaccine and the MMR vaccine . Conversely, Baxter et al analyzed cases of hearing loss after the administration of different vaccines from 2007 to 2013 and did not evidence any correlation between the two events.…”
