Shingles vaccine could cut risk of major cardiovascular events, research finds
Research suggests that the shingles vaccine is linked to a significantly lower risk of major cardiovascular events in people with existing heart disease. Vaccinated individuals had reduced risks across multiple outcomes, including heart attack, stroke, heart failure, and death within 1 year. The protective effect may be due to the vaccine preventing inflammation and dangerous blood clots that result from the shingles infection. While promising, the findings come from an observational study. Therefore, more research is necessary to confirm a direct cause-and-effect relationship.
