Immunisations Flashcards
How does active immunity work?
A person is exposed to a disease organism which trigger their immune system to produce antibodies against the disease. Exposure is either through a vaccine or the actual disease.
How does passive immunity work?
A person is given antibodies rather than producing them themselves

Herd immunity occurs when a significant proportion of the population are vaccinated against the disease. This protects those who are unvaccinated.
