Most current Ebola virus (EBOV) vaccine candidates are based on viral vectors, some of which cause side effects or require complex manufacturing. Modified mRNA vaccines are easily produced, safe, and are highly immunogenic. We developed 2 mRNA vaccines based on the EBOV envelope glycoprotein, which differed by the nature of signal peptide for improved glycoprotein post-translational translocation. The mRNAs were formulated with lipid nanoparticles to facilitate delivery. Vaccination of guinea pigs induced EBOV-specific IgG and neutralizing antibody responses and 100% survival after EBOV infection. The efficacy of our mRNA vaccine combined with preclinical safety data supports testing in clinical studies.

Scientific Reports
Lipid-like nanoparticles (LLNs) have shown great potential for RNA delivery. Lipid-like compounds are key components in LLNs. In this study, we investigated the effects of local structural transformation of lipid-like compounds on delivery of messe...
