Detailed explanation-1: -So a vaccine is a biological preparation that provides the active acquired immunity to a particular infectious disease. So it is going to provide the active So it is going to provide the active acquired immunity.
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: -Vaccination (immunization) is a way to trigger the immune response. Small doses of an antigen, such as dead or weakened live viruses, are given to activate immune system “memory” (activated B cells and sensitized T cells). Memory allows your body to react quickly and efficiently to future exposures.
Detailed explanation-4: -Pathogens most commonly enter the body across the epithelial barriers of the mucosa lining the respiratory, digestive, and urogenital tracts, or through damaged skin, and can then establish infections in the tissues. Less often, insects, wounds, or hypodermic needles introduce microorganisms directly into the blood.
Detailed explanation-5: -Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid. Also, the normal flow of urine washes out microorganisms that enter the urinary tract. to identify and eliminate organisms that get through the body’s natural barriers.
