These observations highlight differences between the immunogenicity of multivalent recombinant protein nanoparticles where immunogens are expressed, purified, and characterized ex vivo prior to delivery of a fixed antigen dose and repRNA, which enables streamlined manufacturing, but the final antigen dose depends on in vivo expression
