COVID-19 Vaccines Offer Continued Protection Against Heart Problems, Study Finds
A new study, drawing data from over 1 million patients within a US Department of Veterans Affairs (VA) health system, indicates that updated COVID-19 vaccines provide significant protection against cardiovascular disease. The research, published in JAMA Internal Medicine, found the 2024–2025 vaccine protected against "major adverse cardiovascular events," which include cardiovascular death, heart attack, stroke, and hospitalization for heart failure. This benefit was particularly notable for individuals over age 75 and those with underlying medical conditions.
Updated COVID-19 vaccines continue to offer significant protection against cardiovascular disease, a new study has found. The research indicates these benefits are particularly strong for individuals over age 75 and those with existing underlying medical conditions.
The study utilized data from more than 1 million patients within a US Department of Veterans Affairs (VA) health system. It specifically examined the efficacy of the 2024–2025 COVID-19 vaccine.
The findings, published in JAMA Internal Medicine, showed that the vaccine protected against "major adverse cardiovascular events" (MACE). These events encompass cardiovascular death, heart attack, stroke, and hospitalization due to heart failure.
This research builds upon previous data that demonstrated COVID-19 vaccines significantly reduce the risk of COVID-19-associated cardiovascular issues, particularly heart attacks and strokes. The recent study confirms that this protection holds true even as the virus evolves and population-level immunity shifts.
According to Ars Technica, despite these continued benefits, anti-vaccine rhetoric has contributed to a decrease in overall vaccination rates.
