What is a Vaccine?

A vaccine is any preparation intended to produce immunity to a disease by stimulating an immune response (such as the production of antibodies)

This immune response will react rapidly upon exposure to the

pathogen and thereby prevent illness

“With the exception of safe water, no other modality, not even antibiotics, has had such a major effect on mortality reduction...”
