Two doses of the Pfizer-BioNTech vaccine, two different side effects: Skin and eye

Area of Science:

• Ophthalmology
• Dermatology
• Vaccinology

Background:

• The Pfizer-BioNTech COVID-19 vaccine has demonstrated high efficacy and safety.
• Adverse events following immunization (AEFIs) are closely monitored.
• Ocular and dermatological side effects are rare but documented post-vaccination.

Observation:

• A 47-year-old male developed right eye pain, reduced vision, and redness three days after his second Pfizer-BioNTech vaccine dose.
• The patient also reported an erythematous, morbilliform rash three days after the first vaccine dose.
• Clinical examination revealed uveitis and secondary inflammatory glaucoma in the affected eye.

Findings:

• The patient was diagnosed with vaccine-associated uveitis and inflammatory glaucoma.
• This case represents the first reported instance of both ocular and cutaneous side effects following the Pfizer-BioNTech vaccine.
• The temporal association suggests a potential link between the vaccine and the observed adverse events.

Implications:

• This case highlights the importance of monitoring for both ocular and dermatological adverse events post-Pfizer-BioNTech vaccination.
• Further research may be needed to understand the immunological mechanisms underlying these rare side effects.
• Clinicians should be aware of this potential association when evaluating patients with new-onset eye or skin conditions after vaccination.
