Cholera advice prior to travel

Until the early 1990s it was common practice for intending travellers to be vaccinated against cholera. The vaccine was often administered combined with typhoid vaccine, and despite the frequent incidence of significant side effects, both doctor and traveller would feel somehow satisfied that the risk of any disease was now largely avoided. Certification of cholera vaccination was often required for admission to various countries, a custom that still exists at some borders, yet not officially required by the WHO for any country.
