Could someone please explain how this can be the case? I understand the vaccine works by stimulating antibody production, which prevent you from becoming ill by binding to the virus and disabling it should it enter your system. How then could the virus be spread further if it's already been disabled?
DMA Design (which later became Rockstar North, developers of Grand Theft Auto) were formed in Dundee. Not exactly the middle of nowhere, but probably not where you'd expect to find one of the world's most popular video game franchises.
