An investigational vaccine seems to be effective against the most common strain of norovirus and has been found to reduce the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent.
A a research has suggested this. Currently, there is no treatment or cure for norovirus, the most common cause of severe GI infection in the US.
Lead author David I. Bernstein, MD, MA, professor of pediatrics at Cincinnati Children's Hospital Medical Center and the University of Cincinnati, said that norovirus truly is a global issue and most if not everyone has experienced it to some degree.
Neither the participants nor the researchers knew in advance who received the vaccine and who did not. In the vaccine group, 26 (52 percent) were infected, as were 29 (60 percent) of those in the non-vaccine group.
In people who received the vaccine, 10 (20 percent) suffered from mild, moderate or severe vomiting and/or diarrhea versus 20 (42 percent) in the non-vaccine group, a 52 percent reduction in symptoms.
