I'm hoping they have good success here with these clinical trials. Earlier trials have already proved this concept works in theory, and that it reduces or eliminates 60+% of severe v* and d* and for about 30% of the recipients protects from infection altogether. I hope they do better this round, even though the earlier studies weren't a total disappointment. All of us will still need to work on our anxiety and keep up with better than good handwashing but this may reduce a great source of anxiety for us, and protect a lot of people who are vulnerable to more serious physical harms from noro.
