Detailed explanation-1: -A vaccine is a substance that is introduced into the body to stimulate the body’s immune response. It is given to prevent an infectious disease from developing and the person becoming ill. Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease.
Detailed explanation-2: -Summary. Vaccines help reduce the risk of certain illnesses by introducing dead or weakened versions of disease-causing germs (bacteria or viruses) to the immune system which stimulate the production of antibodies to provide immunity against one or several diseases.
Detailed explanation-3: -The invading microbe or pathogen is called an antigen. It is regarded as a threat by the immune system and is capable of stimulating an immune response. Antigens are proteins that are found on the surface of the pathogen. Antigens are unique to that pathogen.
Detailed explanation-4: -The way the body defends itself against substances it sees as harmful or foreign. In an immune response, the immune system recognizes the antigens (usually proteins) on the surface of substances or microorganisms, such as bacteria or viruses, and attacks and destroys, or tries to destroy, them.
