New evidence suggests that COVID-19 vaccines may reduce the risk of heart attacks, strokes, and other serious complications

  • MACE is a broad term covering serious conditions like cardiovascular death, heart attack, stroke, or hospitalization for heart failure.
  • The study, which analyzed data from over 1 million U.S. veterans, found that vaccination was associated with a 38 percent lower risk of COVID-related MACE at 8 months.
