God damnit, when are people going to use google and get some facts. It's that easy. Being vaccinated does not stop you getting a disease. Only a space suit will do that. But being vaccinated stops you getting really sick and stops you spreading the virus to others (your body can fight the virus better and it doesn't migrate to the upper respitory tract in huge numbers). The workers housemats/family have all come back negative. So the vaccine has done precisely what it said on the box.
