 What was the breakthrough then that made you able to do it? The breakthrough really was designing a part of the malaria parasite and formulating it in a way that it gives really strong immune responses. You need spectacularly high levels of antibodies to protect against malaria. So it was a way of making the antigen into a small nanoparticle, as we call it, that induces stronger immunity and immunity that is durable. Are we on the way to eradicating this disease, do you think?
