If you are traveling to an area of the world where you might be exposed to cholera, there are effective and safe oral cholera vaccines available. Dukoral provides short-term protection of 85–90 percent against the O1 strain 4–6 months following immunization. Shanchol provides longer-term protection against O1 and O139 in children under the age of five. Both vaccines are administered in two doses given between seven days and six weeks apart. Dukoral is given in 150 milliliters of safe water.
