What role do T-cells play in the immune system?

Back

T-cells are a type of white blood cell that help to destroy infected cells and coordinate the immune response.

Front

What is the significance of vaccinations in the immune system?

Back

Vaccinations help to 'prime' the acquired immune system by exposing it to a harmless form of a pathogen, allowing it to respond more effectively in the future.

Front

What are antigens?

Back

Substances that trigger an immune response, often found on the surface of pathogens.
