Vaccines against H. pylori can be used as prophylactic vaccines to prevent the infection or as therapeutic vaccines to cure the infection, to improve the eradication success of standard regimens or to reduce the bacterial density in the gastric mucosa and the risk for emergence of antibiotic resistant strains. In recent years, many attempts, using various H. pylori antigens such as urease, CagA, HP-NAP, HspA or combinations, many adjuvants and different routes of immunisation have been made to create vaccines against H. pylori infection. Although some attempts are promising, no effective and safe vaccine against H. pylori is currently available for humans. New directions for immunisation with the use of DNA, living vectors, microspheres etc. are currently under evaluation. The vaccination plan and the groups who should receive vaccination are still to be determined but the vaccination will be useful, especially in developing countries read more ...
