Brief Summary

The goal of this randomized, double-blind, placebo-controlled clinical trial is to investigate the immunological effects of influenza vaccination outside of the influenza season on arterial inflammation in patients with a recent acute myocardial infarction (AMI). The primary objective is to compare the effects of influenza vaccination to those of a placebo in reducing post-myocardial infarction coronary inflammation as measured by coronary computed tomography angiography (CCTA). The main questions it aims to answer are: Does influenza vaccination reduce arterial inflammation as measured by CCTA at week 8 after percutaneous coronary intervention (PCI) in comparison to baseline? Does influenza vaccination modulate systemic inflammation as measured by blood biomarkers and in-vitro challenge tests at week 8 after PCI in comparison to baseline? Researchers will compare the effects of influenza vaccination with those of a placebo.

Eligibility Criteria

Inclusion Criteria: * Patients with a diagnosis of non-ST-segment elevation myocardial infarction * A finalized coronary PCI * Male or non-fertile female subjects ≥18 years. (Females without childbearing potential, postmenopausal women and women with a history of hysterectomy or other medical conditions that preclude pregnancy) * Written informed consent * A CCTA can be scheduled within 7 days after PCI Exclusion Criteria: * Has received influenza vaccination within 6 months * Other vaccination planned within 8 weeks (including covid-19 booster doses) * Severe allergy to eggs or previous allergic reaction to influenza vaccine * Cardiac surgery or staged PCI planned within 8 weeks * Coronary stent involving the proximal RCA * Suspicion of febrile illness or acute, ongoing infection * Hypersensitivity to the active substances or ingredients of Vaxigrip or against any residues, such as eggs (ovalbumin or chicken proteins), neomycin, formaldehyde and octoxinol * Subjects with endogenic or
