Risk of myocarditis and pericarditis after the COVID-19 mRNA vaccination in the USA: a cohort study in claims databases.

Background: Several passive surveillance systems reported increased risks of myocarditis or pericarditis, or both, after COVID-19 mRNA vaccination, especially in young men. We used active surveillance from large health-care databases to quantify and enable the direct comparison of the risk of myocarditis or pericarditis, or both, after mRNA-1273 (Moderna) and BNT162b2 (Pfizer-BioNTech) vaccinations.

Methods: We conducted a retrospective cohort study, examining the primary outcome of myocarditis or pericarditis, or both, identified using the International Classification of Diseases diagnosis codes, occurring 1-7 days post-vaccination, evaluated in COVID-19 mRNA vaccinees aged 18-64 years using health plan claims databases in the USA.

ISPOR, the FDA, and the Evolving Regulatory Science of Medical Device Products.

The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) is a key venue for members from private industry, government, and academia to collaborate and share advances in regulatory, clinical, and reimbursement science for drugs, devices, and diagnostics. In parallel, the US Food and Drug Administration (FDA) "is responsible for advancing the public health by helping to speed innovations that make medical products more effective, safer, and more affordable." In 2012, the Medical Device Innovation Consortium (MDIC) was formed as a public-private partnership bringing together government, industry, and nonprofit organizations to advance approaches that promote patient access to safe, innovative medical technologies.
