COVID drugs and vaccines: silent threat to hearing?
NCT ID NCT07254442
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at whether medications used for COVID-19 or the COVID-19 vaccine can harm hearing. Researchers compared hearing test results among 90 adults aged 18-35: those who had COVID-19 and took medications, those who had COVID-19 but took no medications, and a healthy control group who never had COVID-19. The goal was to gather knowledge, not to test a new treatment.
