Answer:
Answer:When the familiar antigens are detected, B-lymphocytes produce antibodies to attack them. Vaccines prevent diseases that can be dangerous, or even deadly. Vaccines greatly reduce the risk of infection by working with the body's natural defenses to safely develop immunity to disease.

Answer:
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. Vaccines protect vulnerable people in our community – such as very young children, the elderly, or those who are too sick to be immunised.
