Universal T‑cell malaria vaccine using HLA‑E presentation

A universal malaria T cell vaccine based on HLA-E presentation

NIH-funded research Oregon Health & Science University · NIH-11319756

This project is developing a vaccine that teaches immune T cells to find and kill malaria‑infected cells across different malaria species for people at risk.

What this research studies

Researchers discovered that pieces of the malaria parasite are shown to the immune system on a molecule called HLA‑E that is very similar across people. They will map the parasite fragments presented on HLA‑E, then use cytomegalovirus (CMV)‑based vaccine vectors designed to program CD8+ T cells to recognize those fragments. The work combines laboratory assays, analysis of blood samples from donors, and animal model testing to check immune responses and safety. The long‑term aim is a single vaccine that protects against multiple Plasmodium species by targeting conserved parasite proteins.

Who could benefit from this research

Good fit: People at risk for malaria, such as residents of or travelers to malaria‑endemic regions, would be the intended participants in future vaccine trials.

Not a fit: People not exposed to malaria or those with severely weakened immune systems may not receive benefit from this vaccine approach.

Why it matters

Potential benefit: If successful, this could produce a broadly protective malaria vaccine that works against many parasite species by training T cells to target conserved parasite proteins.

How similar studies have performed: CMV‑vector vaccines have produced strong CD8+ T cell responses in animal studies and shown promise in other infectious disease models, but using HLA‑E to create a universal malaria vaccine is a novel approach that has not yet been tested in humans.
