The vaccine is called AT04A and has already entered a human clinical trial, which is expected to deliver results by the end of this year.
If the vaccine is found to be safe and effective in humans, researchers say that it would offer a long-term therapeutic strategy for high cholesterol; rather than taking statins every day, patients could simply have an initial injection, followed by an annual booster.
LDL cholesterol is often referred to as "bad" cholesterol; high LDL levels can lead to atherosclerosis. This is the accumulation of fatty deposits, or plaque, in the arteries. Over time, plaque buildup can cause the arteries to narrow, restricting blood flow.
