Vaccine to prevent heart attacks and strokes by targeting inflammation and cholesterol

Nanotechnology-based cardiovascular vaccines

NIH-funded research University of California, San Diego · NIH-11243503

This project develops a vaccine that trains the immune system to reduce artery-clogging inflammation and lower cholesterol for people at risk of heart attack and stroke.

What this research studies

From a patient's perspective, researchers are creating a vaccine that teaches your immune system to make antibodies against two targets linked to artery disease: S100A9 (inflammation) and PCSK9 (cholesterol). They attach small pieces of these targets to harmless plant virus-like particles to prompt a strong, lasting immune response. The team has shown protection in mouse models and will refine the vaccine design and delivery in the lab. The goal is a longer-lasting preventive option so people may not need lifelong daily drugs.

Who could benefit from this research

Good fit: Adults at increased risk of atherosclerotic cardiovascular disease—such as those with high LDL cholesterol, existing plaque, or prior heart attack or stroke—would be the most likely candidates.

Not a fit: People whose heart problems are not caused by atherosclerosis, or those with contraindications to immune-based therapies or vaccines, may not benefit from this approach.

Why it matters

Potential benefit: If successful, this vaccine could lower the risk of heart attacks and strokes and reduce the need for lifelong cholesterol or blood-thinning medications.

How similar studies have performed: Monoclonal therapies targeting PCSK9 have successfully lowered LDL cholesterol in patients, but vaccines for atherosclerosis are still experimental and S100A9-targeting vaccines are a novel approach.
