The vaccine has a long way to go as it's only in phase 1 testing but it's something to look forward to.

Again, we don't know what the side effects of this vaccine are, if indeed there are any. I would guess that children and those in an environment with more exposure to the norvirus would be the likely candidates for this vaccine. If all of them get it, then it's less likely for us to get it even if we don't get the vaccine.
