## Contribution

The paper highlights the rare but important link between influenza vaccination and pericarditis, contributing to public health and clinical awareness.

## Key findings

- Acute pericarditis following influenza vaccination is rare but documented in medical literature.
- Understanding the mechanisms and clinical presentation of vaccine-induced pericarditis is crucial for healthcare professionals.
- Recognizing this rare condition helps in proper diagnosis and patient education.

## Abstract

Acute pericarditis is an inflammatory condition involving the pericardium, the double-layered sac that surrounds the heart. It is characterized by chest pain, typically pleuritic and sharp, along with other clinical and laboratory findings indicative of pericardial inflammation. While acute pericarditis following influenza vaccination is rare, it has been reported in medical literature. The relationship between vaccinations, including the influenza vaccine, and pericarditis is particularly interesting, as it has implications for public health and vaccination programs. Understanding the pathophysiological mechanisms behind vaccine-induced pericarditis and recognizing the clinical presentation are essential for healthcare professionals to diagnose, manage, and educate patients appropriately.
