“…Even when a reduced dose of S19 (1/20-1/100 of the standard dose) was used to vaccinate pregnant cattle, abortions in post-inoculation were still observed, although this reduced dose appeared to be less abortigenic (57,58). The use of the reduced dose vaccine did not eliminate the problem of persistent titers (51,59,60). In fact, these titers lasted about the same amount of time as the full dose (60).…”

Besides insufficient protection, killed vaccines such as 45/20 can also induce persistent antibody titers that can interfere with the commonly used serological tests [7,14,18].…”

Sin embargo, la persistencia de títulos en las pruebas serológicas convencionales es el principal inconveniente para su uso (37,38,39).…”
