Reducing the Risk of Stroke and Heart Attack: Study Shows the Shingles Vaccine’s Potential

Shingles, also known as herpes zoster, is a viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox. It is characterized by a painful rash that typically appears on one side of the body. Though shingles itself can be debilitating, recent research suggests that the shingles vaccine may offer more benefits than initially thought, including reducing the risk of stroke and heart attack.

The Link Between Shingles and Stroke/Heart Attack Risk

A growing body of scientific evidence indicates that shingles may increase the risk of stroke and heart attack. The varicella-zoster virus, which lies dormant in the nervous system after a chickenpox infection, can reactivate later in life and cause shingles. During this reactivation, the virus can trigger inflammation within the body, which can have serious consequences for cardiovascular health.

Studies have shown that individuals who develop shingles have a higher risk of developing stroke and heart attack compared to those who do not. This association is believed to be related to the inflammatory response caused by the virus, which can lead to the formation of blood clots, atherosclerosis, and other vascular complications.

The Shingles Vaccine’s Potential for Reducing Stroke/Heart Attack Risk

The shingles vaccine, also known as Zostavax or Shingrix, has been proven effective in reducing the risk of shingles and its complications, including postherpetic neuralgia (PHN), a condition characterized by persistent nerve pain following a shingles outbreak. PHN can significantly impact an individual’s quality of life and has been associated with increased cardiovascular risk.

Recent research has shed light on the potential cardiovascular benefits of the shingles vaccine. A study published in the Journal of the American College of Cardiology examined the medical records of over 23,000 adults aged 50 and older who received the shingles vaccine. The analysis revealed a 10% reduction in the risk of stroke and a 15% reduction in the risk of heart attack among vaccinated individuals compared to those who did not receive the vaccine.

These findings suggest that the shingles vaccine may have a protective effect on the cardiovascular system, potentially due to its ability to reduce inflammation triggered by the varicella-zoster virus. By preventing shingles or mitigating its severity, the vaccine may reduce the risk of adverse cardiovascular events.

Other Benefits of the Shingles Vaccine

Beyond its potential impact on stroke and heart attack risk, the shingles vaccine provides several other benefits. Firstly, it significantly reduces the likelihood of developing shingles, which can cause debilitating pain and discomfort. By preventing shingles, the vaccine also minimizes the risk of postherpetic neuralgia, which can persist long after the rash has healed.

Additionally, the shingles vaccine has been shown to enhance the overall immune response in older adults. As we age, our immune system becomes less efficient, making us more susceptible to various infections and diseases. By boosting immune function, the vaccine not only protects against shingles but also improves overall health and well-being.

Who Should Get the Shingles Vaccine?

The Centers for Disease Control and Prevention (CDC) recommends that adults aged 50 and older receive the shingles vaccine. This age group is at the highest risk of developing shingles and its associated complications. However, individuals who have previously had shingles or received the previous version of the shingles vaccine, Zostavax, are also advised to get vaccinated with the newer and more effective Shingrix vaccine.

It’s important to note that even individuals who have had shingles in the past can benefit from vaccination. The vaccine not only reduces the risk of recurrent shingles but may also provide additional protection against stroke and heart attack.

The Safety and Effectiveness of the Shingles Vaccine

The shingles vaccine has been extensively studied and has demonstrated a high level of safety and efficacy. Common side effects of the vaccine include injection site reactions such as redness, swelling, and pain. Some individuals may also experience mild flu-like symptoms for a short period after vaccination. Serious side effects are rare but can include severe allergic reactions.

It is crucial to consult with a healthcare professional before getting vaccinated, especially for individuals with compromised immune systems or certain medical conditions. They can provide personalized advice based on an individual’s specific health circumstances.


Reducing the risk of stroke and heart attack is a goal shared by healthcare professionals and individuals alike. The shingles vaccine, with its potential to decrease the likelihood of shingles and its associated complications, offers a promising avenue for achieving this goal. Research indicates that the vaccine may provide additional benefits by reducing the risk of stroke and heart attack, possibly due to its anti-inflammatory properties.

Given the potential advantages, it is highly recommended for individuals aged 50 and older to consider getting vaccinated against shingles. Consulting with a healthcare professional is essential to understand the specific benefits and risks associated with the vaccine in individual cases. By taking proactive measures such as vaccination, we can reduce the burden of shingles and potentially lower the risk of life-threatening cardiovascular events.[2]
