Vestibular neuritis after COVID-19 vaccination

Area of Science:

• Neurology
• Infectious Diseases
• Vaccinology

Background:

• Coronavirus disease 2019 (COVID-19) is a significant global health concern, primarily manifesting as pneumonia.
• COVID-19 vaccination is crucial for mitigating disease spread, mortality, and morbidity.
• Vestibular neuritis (VN) is an acute vestibular disorder characterized by sudden vertigo, nausea, and unsteadiness, potentially linked to viral reactivation or autoimmune processes.

Observation:

• A case report details a 54-year-old male experiencing VN symptoms within three days post-COVID-19 vaccination.
• This represents the first reported instance of VN following COVID-19 vaccination.
• No prior reports link VN to COVID-19 vaccination or other viral inoculations.

Findings:

• The temporal association suggests a possible link between COVID-19 vaccination and the onset of VN.
• The exact etiological relationship between the vaccine and VN remains undetermined.
• This case introduces VN as a potential, albeit rare, adverse event following COVID-19 vaccination.

Implications:

• Clinicians should consider VN in patients presenting with acute vestibular symptoms after COVID-19 vaccination.
• Further research is warranted to investigate the potential association and underlying mechanisms.
• Awareness of this potential adverse event is important for vaccine safety monitoring.
