Shingles Vaccine Can Reduce Heart Disease and Stroke Risk

Key Points:

• A study of over 70,000 adults aged 60+ found that the Shingrix shingles vaccine is linked to a 9% longer cardiovascular disease-free lifespan and reduced risks of heart disease, heart failure, and stroke compared to the older Zostavax vaccine.
• Experts suggest the vaccine may protect the heart by preventing varicella-zoster virus-induced inflammation in blood vessels and potentially by modulating immune responses, though causation has not been proven.
• Additional research indicates shingles vaccination is associated with lower risks of major cardiac events, stroke, heart failure, and even dementia, highlighting broader potential health benefits.
• Despite recommendations for adults 50 and older, only about 42% receive the shingles vaccine, due to side effects, misconceptions about shingles severity, cost concerns, and logistical challenges in vaccine administration.
• Health professionals emphasize that while shingles vaccination may reduce cardiovascular risk, traditional measures like a heart-healthy diet, regular exercise, smoking cessation, and managing blood pressure remain essential for heart and stroke prevention.
