I really don't think that this vaccine could give anyone a norovirus infection. It is not even a real virus, it is a virus like particle. I'd say any vaccine that has live attenuated virus could give you the disease even though that response would be unlikely. Also, I'd take my chances with the side effects I think because they would be mild and even if I were somewhat nauseated I could certainly manage that with antiemetics and anti anxiety drugs. No guarantee that that would work with a full blown norovirus.
