Key result
Influenza vaccination linked to recurrent pericarditis in a case report supported by positive rechallenge.
Why the study?
Pericarditis following influenza vaccination is very rarely reported, and its potential causal relationship remains unclear.
Population
One 87-year-old patient with pericarditis after influenza vaccination
Comparison
Recurrence of pericarditis after initial and subsequent influenza vaccination
Design
Case report with literature review
Follow-up
6 years

May prompt vaccination history review in recurrent pericarditis; leaves open causality and incidence in larger populations.
Case Report (n=1)
Influenza vaccination may be a rare cause of pericarditis, and recent immunization should be considered in the differential diagnosis of elderly patients presenting with chest pain.
Mei et al. (2018) conducted a case report in Pericarditis (n=1). Influenza vaccine was evaluated on Occurrence and recurrence of pericarditis. Influenza vaccination was identified as the likely cause of recurrent pericarditis in an 87-year-old man, supported by a positive rechallenge and a 6-year symptom-free period after avoiding the vaccine.
