GUYS!!!! Someone HAS to be immune! If it ever actually happens, it will most likely spread through the air, which means anyone who doesn't turn into a zombie immediately is already immune! Also, what if it spreads like any other infection?? TOO MANY PEOPLE WOULD BE KILLED BEFORE WE REALIZED THESE THINGS! Movies and games have conditioned us to believe there is no way to stop the spread of infection, and that the infection would spread incredibly quickly. Don't make assumptions based on television, if there WAS a zombie virus, we WOULDN'T KNOW ANYTHING about how it actually works unless we tested it.
