Is there a vaccine you can get to prevent cholera?

Oral cholera vaccine: Yes, vaccines to offer protection from Cholera do exist, but are not likely to be readily available in a general practitioner's office. Here is more information : http://www.who.int/topics/cholera/vaccines/en/

Yes - Vaxchora: was approved in 2016. “The FDA recently approved a single-dose live oral cholera vaccine called Vaxchora (lyophilized CVD 103-HgR) in the United States. The Advisory Committee on Immunization Practices (ACIP) voted to approve the vaccine for adults 18 – 64 years old who are traveling to an area of active cholera transmission.” REF: https://www.cdc.gov/cholera/vaccines.html.
