Question

In your childhood, you must have been given vaccinations to protect yourself against

several diseases. Why did they give vaccination? How do they work?​

Answer 1

Answer:

Vaccines work by preparing the body to fight illness. Each contains either a dead or a weakened germ (or parts of it) that causes a particular disease.The body practices fighting the disease by making antibodies that recognize specific parts of that germ. This permanent or longstanding response means that if someone is ever exposed to the actual disease, the antibodies are already in place and the body knows how to combat it and the person doesn't get sick. This is called immunity.
