Nucleoside-modified RNA for inducing an adaptive immune response
The present invention relates to compositions and methods for inducing an adaptive immune response in a subject. In certain embodiments, the present invention provides a composition comprising a nucleoside-modified nucleic acid molecule encoding an antigen, adjuvant, or a combination thereof. For example, in certain embodiments, the composition comprises a vaccine comprising a nucleoside-modified nucleic acid molecule encoding an antigen, adjuvant, or a combination thereof.
1. A composition for inducing an adaptive immune response in a subject, the composition comprising at least one nucleoside-modified RNA encoding at least one influenza hemagglutinin (HA) antigen, wherein the mRNA molecule encoding the influenza antigen comprises a sequence selected from SEQ ID NO:5 and SEQ ID NO:8.
2. The composition of claim 1 , wherein the at least one isolated nucleoside-modified RNA comprises pseudouridine.
3. The composition of claim 1 , wherein the at least one isolated nucleoside-modified RNA comprises 1-methyl-pseudouridine.
4. The composition of claim 1 , wherein the composition further comprises an adjuvant.
5. The composition of claim 1 , wherein the at least one nucleoside-modified RNA further encodes at least one adjuvant.
6. The composition of claim 1 , further comprising a lipid nanoparticle (LNP).
7. The composition of claim 6 , wherein the at least one nucleoside-modified RNA is encapsulated within the LNP.
8. The composition of claim 1 , wherein the composition is a vaccine.
9. A method of inducing an adaptive immune response in a subject comprising administering to the subject an effective amount of the composition of claim 1 .
10. The method of claim 9 , wherein the composition is administered by a delivery route selected from the group consisting of intradermal, subcutaneous, and intramuscular.
11. The method of claim 9 , wherein the method comprises a single administration of the composition.
12. The method of claim 9 , wherein the method comprises a multiple administrations of the composition.
13. The method of claim 9 , wherein the method treats an influenza infection.
