Most people know the shingles vaccine as a way to prevent the painful rash caused by the varicella-zoster virus. But recent research reveals a surprising new benefit: lowering the risk of heart disease. According to health experts, getting vaccinated against shingles might do more than just protect your nerves—it could also safeguard your heart.
Shingles and Heart Health: The Hidden Link
Shingles, also known as herpes zoster, can lead to severe complications beyond the skin. One of the lesser-known risks is increased inflammation throughout the body, which can raise the likelihood of cardiovascular issues. Studies show that people who experience shingles are at a higher risk for stroke, heart attacks, and other cardiac events, especially in the weeks and months following the outbreak.
This increased risk is thought to be driven by inflammation and vascular stress triggered by the virus. The body’s immune response to shingles can inflame blood vessels, potentially leading to clots, arterial damage, or other cardiovascular problems.
How the Vaccine Helps
The shingles vaccine—such as Shingrix—prevents reactivation of the varicella-zoster virus, reducing the chance of developing shingles by over 90% in older adults. By preventing the virus from reactivating, the vaccine indirectly reduces inflammation and stress on the cardiovascular system.
A recent study published in the Journal of the American Heart Association found that people over 60 who received the shingles vaccine had a significantly lower risk of heart attack and stroke compared to those who did not. The findings add to growing evidence that vaccines can provide broader health protection than once believed.
Who Should Get the Vaccine?
The CDC recommends the shingles vaccine for:
-
Adults aged 50 and older
-
Adults 19 and older with weakened immune systems
It’s a two-dose vaccine, with the second dose typically given 2 to 6 months after the first. It’s important to talk with your healthcare provider to determine if it’s right for you, especially if you have a history of heart disease or are at elevated risk.
Vaccines: A Broader Tool for Preventive Health
This new evidence is part of a larger trend showing that vaccines may offer benefits beyond infection prevention. Just as the flu vaccine has been linked to reduced heart attack risk, the shingles vaccine could become a valuable tool in cardiovascular prevention strategies—especially for aging adults.
Final Thoughts
Protecting yourself from shingles is reason enough to get vaccinated, but the added heart health benefits make the decision even more compelling. In the bigger picture, this is a reminder of how closely connected our immune health is to cardiovascular health.
Talk to your doctor about the shingles vaccine—not just for your skin, but for your heart.
