Reading Time: 5 minutesRisk stratification is like creating a personalized danger-meter for your health. It’s a systematic way to figure out who’s most likely to face a serious problem, like cardiac arrest, and who’s probably in the clear. In the context of the study “Risk Stratification for Future Cardiac Arrest after COVID-19 Vaccination” by Nicolas Hulscher and Peter A. McCullough (published February 26, 2025, in the World Journal of Cardiology), this protocol is designed to spot people at risk of sudden heart failure after getting a COVID-19 vaccine. Let’s break down how the risk stratification protocol works, in simple terms, like a recipe for assessing heart risk.

Reading Time: 6 minutesWhile most people don’t experience serious side effects, a new report highlights a hidden danger that could affect a small but significant group — particularly young, healthy individuals who don’t expect heart trouble. At the forefront of medical research questioning the safety of COVID-19 vaccines, a groundbreaking study titled "Risk Stratification for Future Cardiac Arrest after COVID-19 Vaccination" was published in the World Journal of Cardiology on February 26, 2025. Authored by Nicolas Hulscher, MPH, and Peter A. McCullough, MD, MPH, this peer-reviewed report introduces the first protocol to identify who might be at risk of sudden cardiac arrest after receiving the COVID-19 vaccine. This article breaks down the study’s key findings, explains its importance, and connects it to Robert F. Kennedy Jr.’s health agenda as the head of the U.S. Department of Health and Human Services (HHS).
