Nucleic acid vaccines
First Claim
1. A method of vaccinating a subject comprising administering to the subject a nucleic acid vaccine comprising one or more RNA polynucleotides comprising an open reading frame encoding an antigenic polypeptide that is derived from an infectious agent, i) wherein the RNA polynucleotide does not include a stabilization element, or wherein the nucleic acid vaccine is not co-formulated or or co-administered with an adjuvant and ii) is formulated within a cationic lipid nanoparticle having a molar ratio of about 20-60% ionizable cationic lipid:
- about 5-25% non-cationic lipid;
about 25-55% sterol; and
about 0.5-15% PEG-modified lipid, wherein the nucleic acid vaccine elicits an immune response having a longer lasting antibody titer than an antibody titer elicited by a reference nucleic acid vaccine comprising one or more RNA polynucleotides comprising an open reading frame encoding an antigenic polypeptide that is derived from an infectious agent i) wherein the RNA polynucleotide does include a stabilization element or wherein the nucleic acid vaccine is co-formulated or co-administered with an adjuvant and is ii) not formulated within a cationic lipid nanoparticle having a molar ratio of about 20-60% ionizable cationic lipid;
about 5-25% non-cationic lipid;
about 25-55% sterol; and
about 0.5-15% PEG-modified lipid.
