This is based on an interesting concept that has been around for awhile. Essentially this approach is based on a vaccination to induce an immune response to oxidized LDL cholesterol. The data in animals is good, but it obviously won't be clear that this will be therapeutic in patients until it is tested in clinical trials. I believe the company that is developing this is called CardioVax (U.S. based), but I'm not sure.
One thing that I'd be worried about is whether or not this approach could inadvertently induce deleterious immune responses.
