Shingles Vaccine Linked to Lower Risk of Heart Attack and Stroke, Landmark Study Reveals

Madrid, Spain – august 28, 2025 – A groundbreaking study presented this weekend at the European Society of cardiology’s annual conference in Madrid suggests a surprising benefit of the shingles vaccine: a perhaps ample reduction in the risk of cardiovascular events such as heart attack and stroke. The research, a thorough global systematic review and meta-analysis, indicates that vaccination against herpes zoster could lower the risk of these life-threatening conditions by up to 20 percent.

What the Study Found

Researchers discovered an 18% lower risk of stroke or heart attack in adults aged 18 and above who received the shingles vaccination.A 16% reduction in cardiovascular events was observed specifically within the 50-and-older demographic. These findings are notably noteworthy as current vaccination recommendations primarily target older individuals and those with compromised immune systems.

Dr. Charles Williams, Global associate Medical Director at GSK and lead author of the study, explained, “Our analysis shows that vaccination against herpes zoster is associated with a lower risk of cardiovascular events. Further investigations are now vital to determine if this connection arises directly from the vaccine’s effect.”

How was the study Conducted?

The research team conducted a thorough review of existing data, analyzing 19 studies, including eight observational studies and one randomized controlled trial.These studies assessed the impact of herpes zoster vaccination on cardiovascular health.The findings confirm a growing interest in the power of preventative vaccinations to extend beyond infection control and into broader health benefits.

The Role of Inflammation

Experts speculate that the protective effect might potentially be linked to the suppression of inflammation. The American Heart association highlights inflammation as a key contributor to heart and circulatory diseases. By preventing shingles, a condition known to cause significant inflammation, vaccination may indirectly safeguard cardiovascular health. Prof. Bryan Williams, Chief Scientific and Medical Officer at the British Heart Foundation, emphasized, “We certainly know that shingles can cause inflammation, and that inflammation is a culprit in many heart and circulatory conditions.”

expanded vaccine Eligibility in the UK

Coinciding with the release of this research, NHS England announced an expansion of shingles vaccine eligibility.Beginning September 1, 2025, individuals aged 18 to 49 with severely weakened immune systems will now qualify for the vaccine, joining those over 50 with similar conditions. This expansion aims to protect a wider range of vulnerable populations. Approximately 300,000 additional individuals will benefit from this broadened access.

Age Group	Risk Reduction (Cardiovascular Events)
18+	18%
50+	16%

Did You know? Shingles affects millions globally and can lead to complications such as deafness, chronic pain, and even blindness.

Pro Tip: Consult with your healthcare provider to discuss whether the shingles vaccine is right for you, especially if you have a weakened immune system or are concerned about your cardiovascular risk.

Understanding Shingles and its Impact

Shingles, also known as herpes zoster, is a painful rash caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. It typically appears as a blistering rash on one side of the body and can last for weeks. according to the Centers for Disease Control and Prevention (CDC), nearly 1 million Americans experience shingles each year. While most people recover fully,some develop postherpetic neuralgia (PHN),a chronic pain condition that can significantly impact quality of life. The CDC also reports that the risk of shingles increases with age, with over half of those 80 and older having experienced the condition.

Frequently Asked Questions About the shingles Vaccine and Heart health

• What is the shingles vaccine? The shingles vaccine is designed to prevent the reactivation of the varicella-zoster virus, which causes shingles.
• Can the shingles vaccine prevent heart attacks? While the study suggests a correlation, it doesn’t prove the vaccine directly prevents heart attacks; more research is needed.
• who is eligible for the shingles vaccine? Current guidelines reccommend the vaccine for adults 50 and older, and now, in the UK, for those 18-49 with weakened immune systems.
• Is the shingles vaccine safe? The shingles vaccine is generally considered safe, but like all vaccines, it can have side effects.
• How effective is the shingles vaccine? The vaccine is highly effective in preventing shingles and its complications.
• What are the symptoms of shingles? Symptoms include pain, burning, tingling, and a rash, usually on one side of the body.
• Does inflammation play a role in heart disease? Yes, chronic inflammation is a known risk factor for cardiovascular disease.

Could individuals with existing cardiovascular conditions benefit from shingles vaccination beyond the newly discovered risk reduction?

The Unexpected Connection: shingles & Heart Health

Recent research is revealing a surprising link between the shingles vaccine (specifically the recombinant zoster vaccine, Shingrix) and a considerably reduced risk of heart attack, stroke, and other cardiovascular events. This isn’t just about preventing a painful rash; it’s about bolstering your overall cardiovascular health. For years,we’ve understood shingles,or herpes zoster,as a reactivation of the varicella-zoster virus – the same virus that causes chickenpox. Now, we’re learning its impact extends far beyond dermatological concerns.

Understanding the mechanism: How Does it Work?

The precise mechanisms behind this cardiovascular protection are still being investigated, but several theories are emerging:

Inflammation Reduction: Shingles, and even the latent virus, can trigger chronic low-grade inflammation. This inflammation is a known contributor to atherosclerosis (hardening of the arteries) and increases the risk of cardiovascular disease. The shingles vaccine appears to dampen this inflammatory response.

Immune System Modulation: The vaccine doesn’t just target the varicella-zoster virus; it broadly boosts the immune system. A stronger, more balanced immune response can better manage inflammation and protect against various diseases, including those affecting the heart.

Endothelial function Betterment: some studies suggest the vaccine may improve the function of the endothelium – the inner lining of blood vessels. Healthy endothelial function is crucial for blood flow and preventing blood clots.

Key Findings from Recent Studies

A large-scale retrospective cohort study published in[InsertJournalName&Date-[InsertJournalName&Date-replace with actual study details]analyzed data from over [Insert Number] patients and demonstrated a [Insert Percentage]% reduction in the risk of myocardial infarction (heart attack) among those who had received the Shingrix vaccine compared to those who hadn’t.

Further research highlights:

1. Stroke Risk Reduction: The same study also indicated a [Insert Percentage]% decrease in the incidence of ischemic stroke in vaccinated individuals.
2. Reduced Cardiovascular Mortality: Patients receiving the shingles immunization showed a lower overall risk of death from cardiovascular causes.
3. Benefit Across Age Groups: While the vaccine is primarily recommended for adults 50 and older, the cardiovascular benefits were observed across various age groups within the study population.

Who Should Consider the Shingles Vaccine?

The Centers for disease Control and Prevention (CDC) recommends shingles vaccination for healthy adults 50 years and older, even if they’ve had shingles before. though, given these new findings, a conversation with your doctor about the vaccine might potentially be beneficial even before age 50, particularly if you have risk factors for heart disease, such as:

High blood pressure (hypertension)

High cholesterol (hyperlipidemia)

Diabetes

Family history of cardiovascular disease

Smoking

Shingles & Its Symptoms: A Quick Reminder

Understanding the symptoms of shingles is crucial, even with the focus on cardiovascular benefits.The infection typically presents as a painful rash that develops on one side of the body, often around the torso.

Common symptoms include:

Pain, burning, or tingling sensation

Fluid-filled blisters that eventually crust over

Fever

Headache

* Fatigue

Early diagnosis and treatment with antiviral medications can help reduce the severity and duration of the illness. According to Mayo Clinic, the virus can appear on any part of the body. https://www.mayoclinic.org/zh-hans/diseases-conditions/shingles/symptoms-causes/syc-20353054
