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: -Immunisation is the introduction of dead or weakened germs in the body of living beings so that in case of an encounter with the same pathogen, the body’s immune system can already have the information to fight against the pathogen.
Detailed explanation-4: -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-5: -Vaccination. The introduction of weak and dead microbes into the body is called vaccination. Vaccines are medicines that contain weakened or dead bacteria or viruses. When a person takes a vaccine, his or her immune system responds by producing antibodies substances that weaken or destroy disease-causing organisms.
Detailed explanation-6: -The microbiota plays a fundamental role on the induction, training and function of the host immune system. In return, the immune system has largely evolved as a means to maintain the symbiotic relationship of the host with these highly diverse and evolving microbes.
