immunity & passive immunity
Passive immunity involves the transfer of antibodies to an animal whereas active immunity involves stimulating the body to produce its own antibodies.
What are the 3 keys for a proper immunization practice?
to vaccinate those animals at risk of infection, to vaccinate at the appropriate stage of life, and to vaccinate with the most effective vaccines
Differentiate between inactivated vaccines & attenuated vaccines
Inactivated vaccines are vaccines with killed microorganisms whereas attenuated vaccines have altered, live microorganisms.
Attenuated viral vaccine
contains live but altered viruses where the viruses can still replicate but not cause disease
Outline the sequence of events that occur in the body in response to a vaccination
Macrophages process the antigen for B-cells & T-cells. IgM is produced about 7 days after antigen presentation. IgG is produced about 14 days then declines. Upon subsequent exposure or booster vaccine IgG is produced within 2-3 days & cell-mediated immunity via T-cells is initiated.
