Theoretical Implications of a Pre-Erythrocytic Plasmodium vivax Vaccine for Preventing Relapses

International audience. Preventing malaria infection through vaccination requires preventing every sporozoite inoculated by mosquito bite: a major challenge for Plasmodium falciparum.

We hypothesise that a candidate P. vivax vaccine with low efficacy against primary infection may substantially reduce transmission by preventing relapses.
