BIOL 2900 Lecture Notes - Recombinant Dna, Herd Immunity, Smallpox Vaccine
Document Summary
Vaccins are produced by growing microbes in a labratory using culture vessels. Because viruses need a host cell to reproduce, they are cultured inside chicken eggs. Immunization - the administration of any antigenic inoculum, which are called vaccines. *remember- the immune response has two steps: primary exposure: - very first time you see the antigen. Antibodies that was produced in the first exposure mark the antigen for destruction so you don"t get sick. - the body passively recieves antibodies from another individual. -antibodies from mom through breast milk (ie, gastro problems: artificial. Active imm is mainly a method of prevention. Active: (activating cells with antigen) acq"d when body makes its own abs or t cells to an ag: naturally. -occurs when the body responds to exposure to pathogens and environmental antigens by mounting specific immune responses ie. getting the flu. - end up completely immune this way: artificial.
