'Granulomatosis with polyangiitis after Pfizer vaccination': a case report

Area of Science:

• Immunology
• Vaccinology
• Rheumatology

Background:

• The COVID-19 pandemic spurred rapid mRNA vaccine development, including the Pfizer-BioNTech vaccine.
• While highly effective, rare autoimmune phenomena have been anecdotally reported post-vaccination.

Observation:

• A case report details a military male experiencing Granulomatosis with polyangiitis (GPA).
• The onset of GPA symptoms followed the initial Pfizer-BioNTech COVID-19 vaccination.

Findings:

• This report documents a rare instance of GPA following SARS-CoV-2 mRNA vaccination.
• The temporal association suggests a potential link between the vaccine and the autoimmune condition.

Implications:

• Further investigation into rare autoimmune risks associated with mRNA vaccines is warranted.
• Understanding these rare events is crucial for vaccine safety monitoring and public health.
