Comment
Effective antibiotic based therapies for eradicating
Helicobacter pylori have been developed in
recent years.1 2
There is, however, an the increasing
problem of antibiotic resistance in H
pylori3 and in the long term the consequence of
large scale eradication programmes could be a reduction in the efficacy of current antibiotic based regimens.
The development of a vaccine against H
pylori which confers long term protective immunity is the best
strategy to circumvent the problem of antibiotic resistance and to
eradicate H pylori on a global scale. The
feasibility of inducing protective immune responses to helicobacter by
oral vaccination with bacterial antigens and a mucosal adjuvant was
initially demonstrated in the H felis murine
model.4-6 Vaccination with both H
pylori urease5 and heat shock proteins (HspA and
HspB)6 protected against subsequent challenge with
H felis. However, H
felis lacks many of the virulence factors present in
H pylori, such
