Pathogen types and the principle of vaccination – basic principles
How it works
Pathogens are organisms or particles that can cause diseases. The most important types of pathogens include bacteria, viruses, fungi and parasites. They differ in structure, way of life and methods of control. The principle of vaccination is based on confronting the immune system in a targeted way with weakened or killed pathogens or their components so that it forms antibodies and can react more quickly in the event of a real infection. Vaccinations thus protect against certain infectious diseases and help prevent their spread.
Recognize and distinguish the main types of pathogens (bacteria, viruses, fungi, parasites) and describe the basic principle of vaccination as the targeted activation of the immune system by harmlessly made pathogens or pathogen components.
