Less is More for the Adult Cholera Vaccine

Posted 19 Aug 2017 by

FRIDAY, Aug. 18, 2017 – Researchers say one dose of cholera vaccine appears to provide about the same protection as the standard two doses, at least for the first six months. They also found that cholera vaccines are highly effective in adults but less so in young children, who are at particular risk of death from the disease. The review of seven clinical trials and six observational studies found that the two-dose vaccine regimen reduced cholera risk on average by 58 percent in adults, but only 30 percent in children under age 5. While one dose of vaccine protected as well as two doses for the first six months, there were no data on long-term protection of a single dose, researchers said. The findings could help guide vaccine use, particularly during outbreaks of the diarrheal disease, according to the researchers. "There continues to be a lot of misinformation on what this vaccine is ... Read more

FDA Approves Vaxchora (Cholera Vaccine, Live, Oral) to Prevent Cholera in Travelers

Posted 30 Jun 2016 by

June 10, 2016 – The U.S. Food and Drug Administration today approved Vaxchora, a vaccine for the prevention of cholera caused by serogroup O1 in adults 18 through 64 years of age traveling to cholera-affected areas. Vaxchora is the only FDA-approved vaccine for the prevention of cholera. Cholera, a disease caused by Vibrio cholerae bacteria, is acquired by ingesting contaminated water or food and causes a watery diarrhea that can range from mild to extremely severe. Often the infection is mild; however, severe cholera is characterized by profuse diarrhea and vomiting, leading to dehydration. It is potentially life threatening if treatment with antibiotics and fluid replacement is not initiated promptly. According to the World Health Organization, serogroup O1 is the predominant cause of cholera globally. “The approval of Vaxchora represents a significant addition to the c ... Read more

Cholera Vaccine Helps Prevent Serious Illness

Posted 9 Jul 2015 by

THURSDAY, July 9, 2015 – An vaccine in a pill protects children and adults against severe cholera, a new study shows. Cholera is an infectious disease spread through contaminated water and food. It is typically found in hot, tropical climates, the researchers explained. The results of the first real-life trial of the vaccine support its use in routine mass vaccination programs to help control cholera in more than 50 countries. In countries where the infection is common, more than 1 billion people are at risk of contracting the infectious disease, the researchers noted. Each year, there are about 2.8 million cholera cases and 91,000 deaths in regions where the disease is common, they added. The study included nearly 270,000 people living in a slum in Dhaka, Bangladesh, the researchers said. All were over the age of 1. They were at high risk of cholera due to overcrowding and poor ...

Haiti Cholera Epidemic Could Sicken 779,000 This Year

Posted 16 Mar 2011 by

TUESDAY, March 15 – The cholera epidemic in Haiti this year will be far worse than the 400,000 cases predicted by the United Nations, new study findings indicate. There could be nearly twice as many cases of the potentially deadly diarrheal disease – an estimated 779,000 – between March and November of this year, according to researchers at the University of California, San Francisco and Harvard Medical School. The discrepancy is important because U.N. projections determine the allocation of resources to fight the disease, said the authors of the study, published March 16 in The Lancet. "The epidemic is not likely to be short-term," Dr. Sanjay Basu, a UCSF medical resident, said in a university news release. "It is going to be larger than predicted in terms of sheer numbers and will last far longer than the initial projections." The cholera epidemic erupted in Haiti after last year's ... Read more
