We have assessed duration of
protective immunity primarily by two procedures; the first is held to be the «gold standard and that is to challenge the vaccinated animal with the virulent organism, the second method is to measure
antibody and compare the
antibody titer to that which is known to prevent infection (e.g. provide sterile immunity).

antibodies for
protective immunity.»

antibody titer test to determine whether she had what vaccination experts regard as a «
protective level» of circulating
antibodies from past vaccinations.
