CDC expert Dr. Karen Wong discusses the risk for cholera in travelers, how it can be prevented, and use of the new vaccine.
Vaxchora® (lyophilized CVD 103-HgR)
The FDA recently approvedExternal 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.
- An area of active cholera transmission is defined as a province, state, or other administrative subdivision within a country where cholera infections may be reported regularly (endemic) or where a cholera outbreak is occurring (epidemic), and includes areas with cholera activity within the past year.
- The vaccine is not regularly recommended for most travelers from the United States, as most travelers do not visit areas with active cholera transmission.
- No country or territory currently requires vaccination against cholera as a condition for entry.
Vaxchora® has been reported to reduce the chance of severe diarrhea in people by 90% at 10 days after vaccination and by 80% at 3 months after vaccination. The safety and effectiveness of Vaxchora® in pregnant or breastfeeding women is not yet known, and it is also not known how long protection lasts beyond 3 – 6 months after getting the vaccine. Side effects from Vaxchora® are uncommon and may include tiredness, headache, abdominal pain, nausea and vomiting, lack of appetite, and diarrhea.
