Vaccination is a way of preventing infectious diseases by administering a quantity of a pathogen which has been treated to weaken or inactivate it, or some material from the pathogen.


This provokes an immune response, and so provides vaccinated individuals with ongoing protection without them undergoing the dangers of suffering the disease itself.


The first vaccination was in the 18th century, against the smallpox virus, using either the virus for cowpox (which, being very similar, gave some immunity), or the fluid from smallpox blisters of mild cases.


Vaccination is usually by injection, but may be administered orally, eg for polio.
