Vaccination is the process of administering weakened or dead pathogens called vaccine to a healthy person, with the intent of conferring immunity against a targeted form of a related disease agent.
- The term was coined by Edward Jenner and adapted by Louis Pasteur for his pioneering work in vaccination.
- Vaccination (Latin: vacca—cow) is so named because the first vaccine was derived from a virus affecting cows: the cowpox virus, a relatively benign virus that provides a degree of immunity to smallpox, a contagious and deadly disease.
- In common speech, 'vaccination' and 'immunization' generally have the same colloquial meaning.
- Vaccination efforts were initially met with some resistance before early success brought widespread acceptance and mass vaccination campaigns were undertaken.
Success of vaccination programs
- The eradication of smallpox, which was last seen in a natural case in 1977, is considered the most spectacular success of vaccination.
- Some people assert that childhood vaccination plays a role in autoimmune disease and autism, though large-scale scientific studies have not shown any link.
