New Cholera Vaccine Approved by FDA
Cholera is rarely an issue in the United States, but travelers to parts of the world with inadequate sanitation or water and sewage treatment may be at risk of getting it due to the bacteria that can be present in contaminated food or water. Cholera can cause severe diarrhea and vomiting which can lead to dehydration that may become life-threatening. The main areas of the world in which cholera is a threat include parts of Africa, Asia, Latin America, India, and the Middle East.
The first and only U.S. cholera vaccine, Vaxchora, was approved on June 10, 2016 as a single oral liquid dose that should be taken at least 10 days before entering a cholera-risk area. The vaccine is not 100% effective, so travelers are advised to still practice safe food and water precautions and wash hands frequently.
