DUKORAL is an oral vaccine designed to protect against cholera, a serious and potentially life-threatening bacterial infection caused by the Vibrio cholerae bacterium. This vaccine works by stimulating the body's immune system to produce antibodies against the cholera bacteria, thereby providing immunity to those vaccinated. DUKORAL is typically recommended for travelers to areas where cholera is prevalent, as well as for individuals living in regions where the disease is endemic. The vaccine is administered as a drink mixed with a buffer solution, making it a non-invasive option for those seeking protection against cholera. It is important to note that while DUKORAL is effective in preventing cholera, it does not provide immunity against other causes of travelers' diarrhea.
