Response of mice to injection of ribosomal fraction from group B Neisseria meningitidis.

abstract：:A nasal vaccine, consisting of outer membrane vesicles (OMVs) from group B Neisseria meningitidis, was given to 12 volunteers in the form of nose drops or nasal spray four times at weekly intervals, with a fifth dose 5 months later. Each nasal dose consisted of 250 microg of protein, equivalent to 10 times the intramu...
