Study Notes
Vaccines and Immunity: Key Facts
- Passive immunity can be produced inside or introduced from outside the body
- Natural immunity is acquired by natural means, while artificial immunity sources are given for a specific purpose
- Vaccines protect individuals directly and prevent spread in the population indirectly
- Herd immunity occurs when a sufficient proportion of a population is immune to an infectious disease
- There are five general types of vaccines: attenuated, inactivated, subunit, toxoid, and RNA vaccines & viral vectors
- Attenuated vaccines contain a weakened form of the pathogen and can replicate inside the host
- Inactivated vaccines cannot replicate and often require several booster doses
- Adjuvants enhance the immune response to antigens by providing "danger signals" to APCs
- Inactivated whole agent vaccines contain killed microorganisms or inactivated viruses
- Toxoid vaccines involve toxins treated to destroy the toxic part, retaining antigenic epitopes
- Vaccines utilizing pathogen components include subunit, recombinant, polysaccharide, and conjugate vaccines
- Some subunit vaccines must be conjugated to an inactivated protein to evoke a response in people with weak immune systems
