Go to Antibiotics & PainkillersWhat is Vaccination?
Vaccination involves introducing a small quantity of a dead or inactive form of a pathogen into the body to stimulate the white blood cells to produce antibodies. If the same pathogen re-enters the body, the immune system can respond quickly and effectively, preventing infection. This creates long-term immunity without causing the disease.
Board notes: Covered by all major boards (AQA, Edexcel, OCR). The concept of herd immunity and the pros and cons of vaccination are important aspects.
Step-by-step explanationWorked example
A child receives the MMR vaccine, which contains weakened versions of the measles, mumps, and rubella viruses. Their lymphocytes recognise the viruses as foreign and produce specific antibodies. Memory cells are also created. If the child is later exposed to the actual measles virus, the memory cells will rapidly produce a large number of antibodies, destroying the virus before it can cause illness.

Common mistakes
- 1Thinking that vaccines cure disease. Vaccines are preventative; they don't cure an existing infection. They train your immune system to be ready for a future infection.
- 2Confusing vaccines with antibiotics. Antibiotics kill bacteria; vaccines stimulate an immune response to pathogens, most often viruses.
- 3Believing that vaccines give you the disease. Vaccines use a weakened or inactivated form of the pathogen that cannot cause the full-blown disease but is enough to trigger a protective immune response.

Frequently asked questions
How does a vaccine work?
A vaccine introduces a harmless version of a pathogen into your body. This triggers your immune system to produce antibodies and memory cells, providing you with long-term immunity against that specific pathogen.
What is herd immunity?
Herd immunity occurs when a large proportion of a population is vaccinated against a disease. This makes it much more difficult for the disease to spread, providing protection for vulnerable individuals who cannot be vaccinated.
