- New analysis links shingles vaccination to lower one-year risk of major cardiac events in older adults with heart disease.
- Study compared 123,411 vaccinated adults with an equal number of unvaccinated controls from 2018–2025.
- Vaccinated participants showed lower risk for major adverse cardiac events, death, heart attack, stroke, and heart failure.
- Researchers say the protective effects might be greater in those with existing cardiovascular disease.
- CDC recommends shingles vaccination for adults 50 and older and for some younger adults with weakened immune systems.
- The study analyzed data from 246,822 US adults with atherosclerotic heart disease.
- Shingles vaccination's cardioprotective effects add to evidence beyond preventing shingles.
- Study presented at the American College of Cardiology’s Annual Scientific Session in New Orleans.
- Shingles can lead to clot formation around brain and heart, potentially causing heart attacks and strokes.
