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.
