Shingles Vaccine Lowers Heart Attack and Stroke Risk 2026

The shingles vaccine has been linked to a lower risk of heart attack and stroke, according to a new study. This finding could have significant implications for public health, especially for older adults who are most vulnerable to both shingles and cardiovascular events.

Study Overview: Shingles Vaccine and Cardiovascular Risk

Researchers analyzed health records from 70,000 people in the United States. They found that those who received the Shingrix vaccine had a 12% lower risk of being diagnosed with a cardiovascular condition within the following three and a half years. This includes heart attacks, strokes, and heart failure.

Dr. Maxime Taquet, a clinical lecturer at the University of Oxford who led the study, emphasized the potential impact. “If confirmed in clinical trials, vaccinating older adults against shingles could prevent hundreds of thousands of coronary heart diseases, strokes, and cases of heart failure worldwide,” he said.

Why the Shingles Vaccine Might Protect the Heart

Shingles is caused by the reactivation of the chickenpox virus, which stays dormant in the body after an initial infection. The condition can cause a painful rash and nerve pain that may last for months or years—a complication called post-herpetic neuralgia.

The inflammation triggered by shingles may increase the risk of blood clots and damage to blood vessels, leading to heart attacks and strokes. By preventing shingles, the vaccine may reduce this inflammatory burden.

Comparing Vaccines: Zostavax vs. Shingrix

The first shingles vaccine, Zostavax, was introduced in 2006 and used a weakened live virus. It was later replaced by Shingrix, a more effective recombinant vaccine. The study specifically looked at Shingrix, which is now the recommended vaccine in many countries.

Potential Impact on Public Health

If the findings are confirmed, the shingles vaccine could become one of the most impactful interventions for protecting heart and brain health in older adults. The benefit is comparable to taking a daily blood pressure-lowering medication, according to the researchers.

Experts estimate that widespread vaccination could prevent thousands of deaths each year. This adds to the existing reasons for older adults to get vaccinated against shingles.

Key Takeaways

• Shingrix vaccine associated with 12% lower risk of cardiovascular events.
• Study involved 70,000 US adults over 3.5 years.
• Benefit similar to blood pressure medication.
• Vaccination could prevent many heart attacks and strokes globally.
• Shingrix is more effective than older Zostavax vaccine.

What This Means for You

If you are 50 or older, consider discussing the shingles vaccine with your healthcare provider. The vaccine is recommended for most adults in this age group, and the potential cardiovascular benefit adds another reason to get vaccinated.

While the study is observational, the findings are promising. Clinical trials are needed to confirm the effect, but the evidence so far is compelling.

FAQ

In conclusion, the shingles vaccine may offer a dual benefit: protecting against a painful condition and potentially safeguarding your heart and brain. As research continues, this could become a key strategy in preventive healthcare for older adults.
