The process of administering a vaccine to an individual to create immunity to a pathogen.

A formulation that contains an inactive pathogen, or parts of it.

Immunity is established after the body is first exposed to a pathogen's antigens, and enables white blood cells to respond quickly to the antigen when the body is re-exposed to it.

When a high proportion of the population have been vaccinated against a disease, the spread is reduced and unvaccinated individuals may be protected.

Evaluating the global use of vaccination

Combined science

Pupils will learn about the use of antibiotics against pathogens, and the development of new drugs and novel treatments for disease.

Pupils learned about non-communicable diseases in humans, including cardiovascular diseases and cancer; and about communicable diseases in humans and plant caused by pathogens including bacteria, viruses, fungi and protists.

This unit explores the body's defences and immune response against pathogens, disease prevention, and vaccines. It covers plant defence responses, and disease detection, and evaluates scientific applications, considering personal, social, economic, and environmental implications.

Defences against pathogens, the human immune system and vaccination

Subjects which particular individuals may be sensitive to, eg, adoption, migration, bereavement or death, divorce, poverty, deprivation.
