Scientists at Oregon Health & Science University target diarrhea, the disease that afflicts millions in the developing world.
Novel vaccine appears to provide immunity to a diarrheal disease that afflicts millions of people in developing countries around the world. The vaccine is developed by the scientists at Oregon Health & Science University who teamed up with OHSU spinoff, Najít Technologies, Inc. In research published in the journal Science Advances scientists working with monkeys reported developing a promising vaccine using bacteria that have been inactivated by a hydrogen peroxide-based approach referred to as HydroVax technology.
‘Targeting campylobacter which is associated with infant growth stunting, can help a lot of people, including kids in developing countries by reducing the damage caused by these bacteria.’

They were able to test the vaccine on several strains of bacteria known as Campylobacter, which circulates naturally among a population of rhesus macaques at OHSU’s Oregon National Primate Research Center.Read More..
They found the vaccine conferred 83% immunity against Campylobacter-associated diarrhea among outdoor-housed rhesus macaques.
"We’re hoping to move forward into clinical trials because this is a huge problem around the world," said co-senior author, Mark Slifka, Ph.D., an OHSU professor and president and chief science officer at Najit.
"Campylobacter has been associated with infant growth stunting. Targeting a disease like this can help a lot of people, including kids in developing countries grow stronger by reducing the damage caused by these bacteria."
Known as bacterial gastroenteritis, the condition is associated with malnutrition among millions of children under 5 each year in developing nations. Research shows that among those who suffer repeated infections, it stunts growth and impairs cognitive development.

Researchers did not observe any adverse reactions among monkeys or mice that were given the vaccine, indicating that it may be safe for people.

Besides harming infants and children in developing countries, Campylobacter is a common source of disease that bedevils travelers worldwide. It also harms thousands of people in the U.S. due to complications associated with foodborne diarrhea including an autoimmune disease known as Guillain-Barre Syndrome.
"Along with the exciting opportunity to help children in developing countries, many people don’t realize how much of a problem Campylobacter is here in the U.S.," said co-senior author Ian Amanna, Ph.D., vice president for research at Najít Technologies. "Studies have shown that these bacteria are responsible for up to $5.6 billion in economic costs annually in America."
In addition to making a Campylobacter vaccine, Najít is already moving ahead with clinical trials involving other hydrogen peroxide-based vaccines targeting West Nile Virus, yellow fever, chikungunya virus and is also working on a universal flu vaccine as well.
