Australian researchers found an increased likelihood of tinnitus and vertigo after COVID vaccinations according to a new study. Although not yet peer-reviewed, researchers identified safety signals, particularly with Moderna or Pfizer for vertigo and Moderna, Pfizer, or AstraZeneca for tinnitus.
Over 65,400 GP visits in Victoria and New South Wales for audiovestibular issues were recorded, with a notable increase within 42 days post-vaccination. However, there was no increase in visits for hearing loss. The study also noted more audiovestibular issues after AstraZeneca vaccination compared to mRNA vaccines.
The study used a self-controlled case series method and suggested that age-related factors could contribute to the higher incidence of vertigo with AstraZeneca. The researchers also acknowledged limitations in not capturing data from healthcare settings outside of general practices.
