has anybody seen this video on the noro vaccine? it's not too graphic but it does mention V & D so be aware. i hope it's not true that noro can live on surfaces for a month? he also states a person can shed the virus for a month? after seeing the video im not sure this vaccine will be worth it afterall, it doesn't seem like it will really prevent it, only make it a slight to mild case when your ill. id like some thoughts on this.
