Travellers' Diarrhoea Vaccine

[merck]

In the last few years there seem to have been several pharmaceutical companies marketing travellers’ diarrhoea vaccines.

One vaccine I’ve seen is Dukoral http://www.dukoral.com/ which claims to give protection against one of the most common causes of travellers’ diarrhoea, enterotoxigenic E. coli (ETEC).

Has anyone one used any of these vaccines for travellers' diarrhoea? Do they work? Any bad reactions?

Thanks in advance for any advice/help.

Just spoke to a doctor from the UK. Apparently Dukoral is marketed in Canada and Sweden for both travellers' diarrhoea and as a cholera vaccine (and has been for a few years). But in the UK, the regulatory authorities looked more closely at the test data and decided that it didn't really work for travellers' diarrhoea so it's only marketed over in the UK for Cholera.
