Study Finds Hearing And Balance Disorders Among COVID-19 Vaccinated
More cases of hearing and balance disorders have been observed after people received COVID-19 vaccines, according to a recent study, which asked vaccinated people to remain alert to such complications.
The Australian peer-reviewed study, published in the Vaccine journal on Feb. 22, aimed to determine whether there was an increase in “audiovestibular events” following COVID-19 vaccination in south-eastern Australia. Audiovestibular refers to conditions related to hearing and balance disorders.
“Healthcare providers and vaccinees should be alert to potential audiovestibular complaints after COVID-19 vaccination,” the authors said.
Increase in Incidences of Vertigo, Tinnitus
Researchers found a rise in vertigo and tinnitus cases after vaccination. Tinnitus is a condition that makes an individual hear sounds like humming, ringing, or rushing, in the absence of external stimuli. Vertigo makes people feel like they’re spinning, and can result in dizziness.
“Our study found an increased relative incidence of vertigo in the 42 days following mRNA vaccines, and an increased relative incidence of tinnitus in the 42 days following both Vaxzevria adenovirus vector and mRNA vaccines,” researchers wrote.
“We are the first to confirm this increased relative incidence of tinnitus and vertigo post COVID-19 vaccines,“ they stated. They speculated that the audiovestibular events may be an ”immune mediated injury” triggered by the COVID-19 vaccines.
No Rise in Cases of Hearing Loss
In the same study, the researchers reported that there was “no increased relative incidence in hearing loss” in the 42 days following any COVID-19 vaccine.
They noted that the U.S. Vaccine Adverse Event Reporting System (VAERS) data and studies conducted on the Finnish and Danish health care registry have found “found no association between sudden sensorineural hearing loss (SSNHL) and COVID-19 vaccination.”
As such, the authors concluded that their analysis “supports the opinion that there is no increased incidence of hearing loss following COVID-19 vaccines.”
The authors pointed out a limitation—that their study could not account for any concurrent COVID-19 infections, which other studies have suggested could be associated with audiovestibular events.
“COVID-19 infection is an important potential confounder of the association between COVID-19 vaccination and audiovestibular events,” they wrote.
Figures
Researchers collected vaccine-related data from two databases in Australia, selecting 45,350 records via SAEFVIC, and 4.94 million records via POLAR, for the time period from January 2021 to March 2023.
