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.
The randomized, multi-center study included 98 people who agreed to drink water containing a significant dose of the virus, 50 who received the injected vaccine and 48 who received a placebo injection that did not contain the vaccine.
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.
