Haemophilus influenza outer membrane protein and its use in vaccination

摘要

This invention relates to recombinant bacterial outer membrane proteins comprising one or more LB1(f) peptides from surface-exposed loop 3 of MOMP P5 of non-typeable H. influenzae. Polynucleotides encoding these recombinant proteins are also covered. The invention also relates to a method of isolating the recombinant proteins and a vaccine composition for use in the treatment of Haemophilus influenzae infection.
