Study Notes
Vaccination
- A process that introduces a vaccine to stimulate the immune system and provide immunity against specific diseases.
- Vaccines can be derived from weakened or killed forms of pathogens, or pieces of pathogens such as proteins or genes.
Vaccine
- A biological substance that helps develop immunity to a specific disease, typically through the stimulation of an immune response.
- Vaccines can prevent infectious diseases by preparing the immune system to recognize and fight pathogens effectively.
Acquired Immunity
- Refers to immunity gained after exposure to a specific pathogen or through vaccination.
- Involves the development of specific antibodies and memory cells that allow for a faster immune response upon subsequent exposures.
Immunosuppression
- A state in which the immune system's ability to respond to pathogens is reduced or entirely inhibited.
- Can be caused by factors such as diseases, treatments like chemotherapy, or medications that suppress immune function.
Immunotoxicity
- Refers to the adverse effects of substances on the immune system.
- Can lead to increased susceptibility to infections or autoimmune diseases as well as may disrupt normal immune function.
Autoimmune Disease
- A condition in which the immune system mistakenly attacks the body's own healthy tissues.
- Examples include lupus, rheumatoid arthritis, and type 1 diabetes, arising from a failure in self-tolerance mechanisms.
