FYI, one of the authors of the study, Andrew Diamos, is a popular twitch streamer, CarlSagan42. He streams a lot of Mario levels created by people that are often puzzle or troll levels. During his stream he'll talk a lot about science, including some of the work he's done in this study.
There's a norovirus vaccine which just completed stage 1 trials[0]. Cool part about it is that it isn't an injection, just a pill you swallow.
It is worth noting that norovirus and rotavirus aren't the only common "stomach bugs" but being immune against both is still a big win.
edit: Just want to add, I'm not dissing on this research. The more separate efforts there are for a safe effective norovirus vaccine the less likely they are to ALL fail. I've just been watching this space closely because I want to be the first in line when someone's vaccine ships.
Luckily, modern medical science isn't based on your imagination. The more vaccines that are available, the better. It doesn't mean that everybody will take them all. In most cases it will be based on risk. However, having had norovirus twice in the past decade, I'd sign up in a moment. Even though it's rarely life-threatening, it's extremely infectious, and extremely unpleasant.
Also, our evolved environment had more random pathogens floating around in it than the modern world does. It looks like many auto-immune diseases are caused by the immune system getting restless with lack of exercise. Throwing more vaccinations at the immune system looks like it should do at least a little bit to reduce the problem.
Norovirus results in about 685 million cases of disease and 200,000 deaths globally a year. It is common both in the developed and developing world.[1]
