Scientists have taken the first steps toward designing a vaccine that could save lives of millions of people. The announcement was made at a medical conference held in London. A team from Lund University in Sweden has discovered a new method which can act to prevent heart attack, and new discovery is the first solution anti-infarct directly addressing its causes.
Heart disease occurs when plaque is deposited on the arteries carrying blood to the heart, and with time they become thinner. Some parts of the plate can be filed off, thereby blocking the artery and causing a heart attack. Among the causes of heart attack include physical inactivity, poor diet, high alcohol consumption, plus hereditary factors.
Professor Jan Nilsson from Lund University, specialist in cardiovascular states that current methods are effective in 40% of cases. Specialist identified a new method, currently unexplored, which could increase the percentage of successful interventions.
Professor Nilsson explained that it is possible to modify the immune response to lower arteries. Team led by Dr Nilsson has developed a vaccine that they tested on mice prone to heart attack, managing to reduce by 70% the number of heart attacks. Vaccine developed, called CVX-210, now expects approval of the competent authorities for the next steps of testing, the one on people.
If the effect recorded in mice is confirmed among people, heart vaccine could be widely used in several years, saving millions of people from death. Cardiovascular problems are the main causes leading to death for large numbers of people worldwide.
