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

  • A new study published in JAMA Internal Medicine indicates that COVID-19 vaccination may be linked to a lower risk of COVID-19-related major adverse cardiovascular events (MACE).
  • 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.
  • This risk reduction was more pronounced and statistically significant among veterans aged 75 or older and those with other medical conditions.
  • Despite limitations such as the study's focus on veterans, researchers believe the findings offer timely evidence for public health discussions about updated COVID-19 vaccines.
