PaxVax’s Vaxchora™ now available as the only U.S. approved vaccine for protection against cholera.
PaxVax, Inc. announced that Vaxchora™ is now available in the United States as the country’s only vaccine for protection against cholera, a highly contagious intestinal diarrheal infection that can cause death in less than 24 hours if left untreated.1
Vaxchora, a single-dose vaccine, was approved by the U.S. Food and Drug Administration (FDA) in June 2016 for use in U.S. adults traveling to cholera-affected areas as an active immunization against disease caused by Vibrio cholerae serogroup O1. Also in June 2016, The Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) voted unanimously to recommend Vaxchora for travelers to areas of active cholera transmission.
Estimated to be widespread in 69 countries, primarily in Africa, Asia, and the Caribbean, cholera is acquired by ingesting contaminated water or food. Annually, millions of people around the world are impacted by this extremely infectious disease.2 A recent report from the CDC suggests that the true number of cholera cases in the U.S. is at least 30 times higher than observed by national surveillance systems.3 Non-vaccine intervention to prevent cholera infection is the avoidance of contaminated water and food, but studies have shown that 98 percent of travelers do not comply with these precautions when travelling.4
The recent events in Haiti, where Hurricane Matthew hit the country on October 4, 2016, have highlighted the serious threat of cholera. Cholera has had a particularly devastating impact on Haiti since 2010, with approximately 10,000 deaths and 800,000 infections. The destruction caused by Hurricane Matthew has worsened the impact of the disease by creating circumstances that allowed cholera to spread and by making its treatment difficult.5,6
“We are excited that Vaxchora is now available to Americans traveling to areas affected by cholera. This is particularly timely in light of the number of U.S. citizens, including members of the U.S. military, joining relief efforts in Haiti,” said Nima Farzan, Chief Executive Officer and President of PaxVax. “Vaccinating those traveling to cholera-affected areas can help mitigate its spread and can help protect them against the disease,” said Farzan.
PaxVax has also made a donation to international medical organization Partners In Health to support the relief efforts in Haiti with specific focus on cholera prevention and treatment.
Vaxchora is not approved for use outside of the United States.
