SAN FRANCISCO — An experimental vaccine is showing promise in terms of protecting people against norovirus, the so-called "cruise ship" virus, according to KMYT-TV.
While research for the treatment is still in its earliest stages, the injectable vaccine has been proven to safely stimulate an immune response in a recent study, the article stated.
According to the article, last year, a nasal spray vaccine was tested, but results were not good enough for researchers who believed the spray only worked against one strain of the multi-strained norovirus.
The injection, however, works against two, which results in "a cross-reaction that provides added protection," the article noted.
"Compared to the placebo, volunteers of all ages mounted a rapid antibody response. The second dose did not appear to give additional protection, which may mean that only a single dose is needed," said John Treanor, chief of the infectious diseases division at the University of Rochester Medical Center in New York.
