Abstract
Disclosed herein are compositions and methods related to mutant viruses, and in particular, mutant influenza viruses. The mutant viruses disclosed herein include mutant M2 sequences, mutant BM2 sequences, and are useful in immunogenic compositions, e.g., as a quadrivalent vaccines. Also disclosed herein are methods, compositions and cells for propagating the viral mutants, and methods, devices and compositions related to vaccination.
Claims8
An immunogenic composition, wherein the composition is a quadrivalent composition consisting of:
- a) two engineered attenuated influenza A viruses consisting of:
- i) H1N1 having a mutant M2 gene comprising SEQ ID NO:
- 1, and
- ii) H3N2 having a mutant M2 gene comprising SEQ ID NO:
- 1;
- and
- b) two engineered attenuated influenza B viruses consisting of:
- i) B/Victoria having a mutant BM2 gene comprising SEQ ID NO:
- 9, and
- ii) B/Yamagata having a mutant BM2 gene comprising SEQ ID NO:
- 9.
A method of stimulating an immune response against influenza A and influenza B comprising administering to a subject in need thereof a quadrivalent immunogenic composition consisting of
- a) two engineered attenuated influenza A viruses consisting of:
- i) H1N1 having a mutant M2 gene comprising SEQ ID NO:
- 1, and
- ii) H3N2 having a mutant M2 gene comprising SEQ ID NO:
- 1;
- and
- b) two engineered attenuated influenza B viruses consisting of:
- i) B/Victoria having a mutant BM2 gene comprising SEQ ID NO:
- 9, and
- ii) B/Yamagata having a mutant BM2 gene comprising SEQ ID NO:
- 9.

- i) B/Victoria having a mutant BM2 gene comprising SEQ ID NO:
- 11, and
- ii) B/Yamagata having a mutant BM2 gene comprising SEQ ID NO:
- 11.
A method of stimulating an immune response against influenza A and influenza B comprising administering to a subject in need thereof a quadrivalent immunogenic composition consisting of
