Vaccination

What is Vaccination?

Vaccination is the administration of a vaccine to stimulate the immune system to develop adaptive immunity to a disease. Vaccines can prevent or ameliorate morbidity from infection.

Historical Background

The concept of vaccination dates back centuries, with early forms of inoculation practiced in various cultures. Edward Jenner's work in the late 18th century with cowpox to prevent smallpox is considered the foundation of modern vaccination.
