"I did all the exams and could not find any other reason other than because of the shots," she told The Epoch Times.

Several studies have linked sudden hearing loss to the vaccine, with the most comprehensive study coming from France. Four hundred cases of post-vaccine sudden sensorineural hearing loss were evaluated, with 345 medical reports assessed by two audiology experts for potential causality.

"[Sudden sensorineural hearing loss] after COVID-19 mRNA vaccines are very rare adverse events," the French authors concluded, adding that these rare adverse events "do not call into question the benefits of mRNA vaccines but deserve to be known given the potentially disabling impact of sudden deafness."

Accumulated Damage

While the cause of hearing loss is unknown, it is usually assumed to be induced by damage to the cochlear, a fluid-filled, spiral cavity in the inner ear that helps process sounds into electrical signals in the brain.

This assumption is based on the fact that cochlear implants, which mimic the work of a natural cochlear, are highly successful in treating hearing loss.

The cochlear is a highly sensitive part of the ear and can accumulate damage from aging, loud sounds, viral infections, and certain chemicals and medications.

These exposures may restrict oxygen to the blood supply of the cochlear, reduce blood flow, increase oxidative damage, or form lesions in the cochlear tissue.
