Vaccines play a critical role in protecting public health by teaching the body how to fight infections before they happen. Instead of exposing individuals to dangerous diseases, vaccines use carefully designed components to trigger immune training without illness.

This process relies on antigens, antibodies, and immune memory, allowing the immune system to respond quickly and effectively when real threats appear.
