What is a vaccination?

What are vaccines and how do they work?

Vaccines are products that are usually given in childhood to protect against serious, often deadly diseases. By stimulating your body’s natural defenses, they prepare your body to fight the disease faster and more effectively.

How do vaccines work?
Vaccines help your immune system fight infections more efficiently by sparking your immune response to specific diseases. Then, if the virus or bacteria ever invades your body in the future, your immune system will already know how to fight it.

Vaccination is a way of saving people’s life by preventing diseases that can kill or make people very sick. Vaccines save 2-3 million lives each year.
