世界首例诺如病毒四价疫苗获批进入临床研究，由上海研发 - 2019年06月05日

What could be the world’s most effective vaccine against the highly contagious norovirus has been given the green light for clinical trials in China, Shanghai scientists said on Tuesday.
When the home-developed vaccine hits the market in three to five years, it is expected to be the most effective of its kind, theoretically providing 80 to 90 percent protection from the virus, according to researchers from the Institute Pasteur of Shanghai under Chinese Academy of Sciences.
The norovirus is the most common cause of acute gastroenteritis. It is widely referred to as stomach flu. Outbreaks are common in cold seasons, like early spring and winter, and young children and elderly people are at particular risk.
