Pathogens have a protein coat or surface, some pathogens continually change the shape of their surface coats (RNA viruses such as flu and HIV). The proteins of the coats are called antigens and are recognised by the immune system (produces antibodies etc). The basis of vaccination is to use part of the coat or pathogen to stimulate the immune response without causing the disease. Antibodies therefore only work against specific pathogens.
