Question

How do vaccines work?

Answer 1

Vaccines:

1. Vaccines are the treatments that are used to improve our immunity to a specific disease.
2. Usually, they are made by using weakened or killed bacteria or viruses.
3. These vaccines trick the immune system into making antibodies.
4. Antibodies are proteins that usually attack bacteria or viruses.
5. For these specific molecules, the pathogen must be introduced into the body.
6. These specific molecules trigger an immune response.
7. These molecules are called antigens.
8. Antigens are present in all viruses and bacteria.
9. These antigens are injected into the body.
10. The immune system learns to recognize them as hostile, invaders, produce antibodies, and remember them for the future.
