Study: Norovirus Vaccine Shown Effective in Human Tests

Researchers testing a norovirus vaccine have some good news for the high-risk nursing home population. During human tests, the vaccine was shown to be highly effective in reducing symptoms of the infection.

The study involved 98 participants who drank water dosed with norovirus. Fifty of those participants received the norovirus vaccine. The results were as follows:

• Twenty-six of the people who were given the vaccine became infected. Ten of them developed mild, moderate or severe vomiting and/or diarrhea. 
• Twenty-nine of the people who were not given the vaccine became infected. Twenty of them developed the above-mentioned symptoms. 

The researchers hope that continued testing will confirm the vaccine's effectiveness and help prevent future norovirus outbreaks.
