Week 8 Flashcards
how is immunity developed?
- as a response to protect the body from attacks by foreign antigens, typically proteins
what are different kinds of immunity? (4)
- innate (natural/native)
- acquired
- resistance
- herd immunity (community)
what is innate immunity? what type of response does it provide?
- immunity present at birth
- provides a nonspecific response
what is acquired immunity?
- immunity protection gained after birth
what is active acquired immunity
- develops after the introduction of a foreign antigen resulting in the formation of antibodies or sensitized T lymphocytes
what is artifical active acquired immunity
- exposure due to immunization
what is passive acquired immunity
- intro of preformed antibodies such as transfusion of antibodies
- or passed from mother to fetus
what is resistance immunity
- the ability to limit pathogen burden
what is herd immunity
- the resistance of a group to invasion and spread of an infectious agent, based on high proportion of individual members of the group being resistant to infection
- ie. if a sufficient proportion of a group is vaccinated, both vaccinated and unvaccinated are protected from the disease
