Immunization with a nucleoside-modified mRNA-LNP vaccine encoding the conserved malaria antigen E140 induced durable humoral immunity in mice and generated invasion-blocking antibodies against Plasmodium vivax. The results highlight E140 as a promising candidate for next-generation malaria vaccines.
