Imagine a young man who receives a vaccine and is protected for life from the consequences of a heart attack. It may seem like science fiction, but the first step towards it has already been taken at the Weizmann Institute of Science in Israel. 

Cardiovascular diseases (CVDs) are the leading cause of death globally, with an estimated 17.9 million deaths in 2016, representing 31% of all global deaths. Currently, there is no effective way to prevent or treat heart attacks. They can cause significant damage to the heart muscle. So, heart attack vaccine development would be a significant breakthrough in cardiology. The ability to regenerate damaged heart tissue could revolutionize the treatment of heart disease, allowing patients to recover faster and potentially reducing the risk of future heart attacks.
