What is vaccination? Write its importance?

Answer» Vaccination is the administration of a vaccine to help the immune system develop protection from a disease.\xa0Vaccines work on the principle of immunization. Vaccines help a body\'s immune system prepare in advance to fight infectious illnesses and potentially deadly diseases caused by infectious agents or their by-products. Vaccines ‘fool’ the immune system into developing a memory for a particular infection by putting something that mimics the microbe we want to vaccinate against, into the body.
