Experimental malaria vaccine aims to block parasite growth

NCT ID NCT05978037

First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time

Summary

This trial tests an experimental malaria vaccine called RH5.2-VLP, given with an adjuvant (Matrix-M) to boost the immune response. Healthy adults aged 18–45 receive three doses, and some volunteers are later exposed to malaria parasites in a controlled setting to see if the vaccine prevents illness. The study evaluates safety, immune response, and the vaccine's ability to reduce parasite multiplication.

What this could lead to
If successful, this vaccine could help prevent malaria illness and reduce deaths from this major global disease.
What could go wrong
This is an early-phase trial with only 41 participants, so results may not apply broadly. The vaccine is being tested for the first time in humans, and its safety and effectiveness are not yet proven.
