Vitiligo Possibly Triggered by COVID-19 Vaccination

Area of Science:

• Dermatology
• Immunology
• Vaccinology

Background:

• COVID-19 vaccines have been associated with various cutaneous side effects.
• Vitiligo, an autoimmune condition causing skin depigmentation, has been rarely reported post-vaccination.

Observation:

• A case of new-onset vitiligo developed two weeks after a patient received a COVID-19 vaccine.
• The patient's vitiligo appeared following vaccination, prompting this case report.

Findings:

• The precise mechanism linking COVID-19 vaccination to vitiligo onset remains unclear.
• A potential link involves inflammatory pathways common to both vitiligo pathogenesis and vaccine immune responses.

Implications:

• This case underscores the importance of monitoring for dermatological adverse events after COVID-19 vaccination.
• Further investigation is warranted to elucidate the relationship between COVID-19 vaccines and vitiligo development.
