The shingles vaccine could protect against a lot more than we thought
The shingles vaccine could protect against a range of serious health issues including strokes, heart attacks, heart failure and atrial fibrillation, according to an astonishing new study. Analysing over a million South Korean adults aged 50 and older, researchers made remarkable discoveries that could revolutionise preventative healthcare practices for these conditions.
Brain injury specialist Natalie Mackenzie explained the significance to Reach: “These findings are exciting. They indicate that the shingles vaccine doesn’t just prevent a painful rash; it can also lower the risk of strokes and heart attacks.
“This study shows how powerful interventions can be – not only does it stop shingles but also protects your heart and brain. For those who qualify, it’s well worth doing your research on these findings to fully understand how it may benefit you.
“This is a major health win for anyone eligible for the jab and has an increased risk. As a brain expert, the efficacy noted in this research is certainly meaningful and could be a great tool for reducing the risk of stroke.”
Mackenzie pointed out that this investigation adds to existing evidence that preventive measures against certain illnesses can yield “unexpected benefits for your overall health”. She also said the results also offer “the potential for clinical consideration”.
This means that people at a higher risk of strokes, such as those with high blood pressure or diabetes, could potentially be considered for the jab. As a preventative measure against strokes rather than just shingles.
Currently, the vaccine is available on the NHS for adults turning 65, those in their 70s and people aged 50 with weakened immune systems.
The study, published in the European Heart Journal, discovered that individuals vaccinated against shingles were 23% less likely to experience cardiovascular issues, such as strokes or heart attacks, compared to those who didn’t receive the jab.
Specifically, it reduced the risk of:
- Stroke by 26%
- Heart attacks by 35%
- Heart failure by 26%
- Heart rhythm disorders like atrial fibrillation by 29%
Overall, men and people under the age of 60 experienced the most significant reductions in risk. The protective effects could last up to eight years, although the risk of these conditions decreased the most two to three years after receiving the jab.
However, the study did have some limitations, namely that the results could vary among different ethnic groups and between the two types of shingles vaccines currently in use. Nonetheless, it does align with previous studies that indicated individuals who contracted shingles faced higher risks of stroke, cardiac events and heart disease.
