The list of potential benefits of shingles vaccines continues to grow.
As previously reported by Fox News Digital, the shot also protects against viral infections and the resulting painful rash, and is therefore linked to a lower risk of dementia.
And now, a new study finds that vaccines can reduce the risk of heart disease for up to eight years.
Research suggests that the risk of dementia can be immersed in common vaccines
In a long-term study, researchers analyzed data over 12 years of over 1.2 million people over 50 in South Korea, focusing on iron vaccination rates and 18 different cardiovascular diseases.

They found that those who received the shingles vaccine had a 23% lower risk of heart problems, including stroke, heart failure and coronary artery disease.
Researchers said the benefits were great for people under the age of 60, perhaps because they had a better immune response.
Blood pressure and risk of dementia share surprising links, studies suggest
The heart health benefits of the vaccine were even more pronounced among men and those with unhealthy behaviors such as sedentary, drinking alcohol, smoking and other symptoms.
The findings were published in the European Journal of Hearts on Tuesday.

The main symptoms of shingles are painful rashes that can lead to serious complications, especially for the elderly and those with weak immune systems.
Without vaccinations, around 30% of people could develop shingles in their lifetime, Yong pointed out.
“In addition to the rash, iron fragments are linked due to their high risk of heart problems, so I wanted to know if getting vaccinated can reduce this risk,” he said in a press release.
“Our research suggests that shingles vaccines may help reduce the risk of heart disease, even in people without known risk factors.”
“Our research suggests that shingles vaccines may help reduce the risk of heart disease, even in people without known risk factors. This means that vaccinations can provide health benefits beyond preventing shingles.”

Researchers shared several possible reasons for the protective benefits of vaccines on heart health.
“A shingles infection can cause vascular damage, inflammation and the formation of coagulation that can lead to heart disease,” Yong said. “By preventing shingles, vaccinations can reduce these risks.”
Potential limitations
Dr. Jasdeep Dalawari of Ingenovis Health Company, a Virginia-based intervention cardiologist and Regional Chief Medical Officer at Vitalsolution, was not involved in the study but provided comments on the findings.

“The results are noteworthy, but require careful interpretation, especially regarding the population of the United States,” he told Fox News Digital.

“We used live vaccines in this study, but the US uses Singlix, a recombinant (non-live) vaccine,” Darawari said. “It is important to note that Singlix is ​​over 90% against shingles compared to 51% of live vaccines.”
The live shingles vaccine contains a weakened form of the water cell shingles virus that causes shingles.

Cardiologists also noted that observational studies show correlation rather than causality, and further research is needed.
“The study included 1.2 million individuals from one ethnic group, with 1.2 million people over the age of 50,” he said. “Expanding the participant pool to include diverse ethnic groups is beneficial in our multi-ethnic society.”

Although the study considered other health conditions, lifestyle factors and socioeconomic status, the researchers agreed that there are several limitations.
“Since this study is based on an Asian cohort, the results may not apply to all populations,” Yong pointed out. “We conducted a rigorous analysis, but this study does not establish a direct causal relationship, so potential biases from other underlying factors need to be considered.”

The team plans to conduct further research into the heart health benefits of nonformal recombinant vaccines containing proteins from the virus.
