Pfizer Vaccine Potentially Linked to Hearing Loss

The World Health Organization is investigating rare instances of hearing loss and other auditory disturbances associated with COVID-19 vaccinations – primarily the Pfizer-BioNTech shots, according to a report from WHO.

Of 11 billion doses given, a WHO newsletter reported 164 cases of hearing loss worldwide among people who had received Pfizer-BioNTech, Moderna or AstraZeneca shots.

There were 367 cases of tinnitus, a hearing condition that causes disrupting ringing, hissing, clicking, roaring or humming in one or both ears. Onset ranged from several minutes to several days, with most occurring within a day.

About 80 percent of the reported tinnitus cases developed after the Pfizer-BioNTech vaccine, according to WHO's analysis.
