|
|
Your body makes antibodies and destroys the invaders
|
|
|
You get a shot with weakened invaders in it
|
|
|
You don’t get sick the next time those invaders enter your body
|
|
|
The antibodies stay in your body to “remember” the invaders
|
Detailed explanation-1: -When a person gets a vaccine, the immune system responds to the antigen as if it were exposed to the actual germ (it makes antibodies and remembers how to defeat it). Then, if the body gets exposed to the actual germ, the immune system can recognize it right away and quickly fight it off to prevent disease.
Detailed explanation-2: -Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.
Detailed explanation-3: -Live-attenuated vaccines Live vaccines use a weakened (or attenuated) form of the germ that causes a disease. Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response.
Detailed explanation-4: -Vaccines work on the principle of immunization. During vaccination, when the immune system first encounters an infectious microbe, it responds against it and then remembers it specifically. So the next time that particular microbe or its close relatives enter the body, the immune system responds with greater vigor.
Detailed explanation-5: -Step 1: Exploratory – Research. Step 2: Preclinical – Safety & Efficacy. Step 3: Clinical – Safety & Efficacy in Humans. Step 4: Regulatory Review & Approval – Licensure. Step 5: Production – Scaling Up. Step 6: Quality Control – Performance Review, Post-Marketing.
