Helicobacter Pylori Vaccination

摘要

A sterile immunogenic preparation of three purified H. pylori antigens (CagA, VacA and NAP) adjuvanted with alum in an isotonic buffer solution for intramuscular injection. The antigens may be administered in conjunction with antibiotics and/or antisecretories. Urease breath testing, stool antigen testing, and/or immunological analysis may be used as correlate(s) of protection against H. pylori infection. Urea may be used to improve VacA solubility.
