Answer 1

As we know our body intially has certain systems to fight against some disease and infections caused by pathogens. So it provide akind of defense mechanism known as immune system . Our body hasT cells , B cells , dendritic cells and macrophages etc which fight against infections . So the process by which the organisms are protected against infection are known as immunization . The immunity can be processed outside and then supplied to the body through vaccine . It enhances the immunity . The types of anti viral vaccines are - inactivated vaccines( inactivated virulent is used to provide immunisation ) , attenuated ( the virulents are active and live and provide broad immune response ) , toxoid ( these are inactivated toxic compounds ) , protein subunits ( fragment of protein is used to create immune response ), conjugate anti - viral vaccine , monovalent and heterotypic vaccine .
