A vaccine helps in time of stimulating the immune system by providing an active acquired immunity against diseases. It  may be either prophylactic or therapeutic. Vaccines confer protection against various infections- bacterial and viral. Most of the situation, vaccines are also given for specific cancers and immune mediated diseases. Anti-Microbials are the substances which provide the protection against any microbial infections. They are again divided into Antibiotics (against bacteria infections), Antivirals (against viral infections), Antifungals (against fungal infections), Antiprotozoal (against protozoal infections), anti-helminths and nematicides (against nematodes and helminths) etc.
