Vaccinating Against Heart Attacks?

Finnish and UK researchers report DNA from oral bacteria and biofilm structures inside atherosclerotic plaques. They hypothesize viral infections can awaken these biofilms, sparking inflammation that ruptures plaques and causes myocardial infarction. If validated, vaccines or anti‑biofilm therapies could become tools for preventing heart attacks. — It reframes heart disease prevention from lifestyle and lipids alone to include infection control, dental health, and potential vaccination strategies.
