Colorado Serum gets full license for RB-51 vaccine

Colorado Serum Company received a full license for the manufacture and distribution of Brucella Abortus Vaccine, Strain RB-51, Live Culture. For the past seven years, the vaccine (under conditional license) has served as a significant factor in the governments 50-plus year effort to eradicate brucellosis from the United States.Brucellosis is a bacterial disease that primarily affects cattle and bison, causing abortions and lowered milk production. As part of the cooperative state/federal brucellosis eradication program, many states currently require each bovine heifer calf (4-12 months old) to be vaccinated with RB-51.The company says the advantage of RB-51 is that it produces immunity while not inducing antibodies that react in standard serological diagnostic tests (eliminating false-positives in diagnosis of infected cattle), nor does it produce an objectionable local reaction at the injection site. The organism is cleared from the blood stream within three days, is not present in nasal secretions, saliva or urine, and does not spread from vaccinated to non-vaccinated cattle.Brucella Abortus Vaccine, Strain RB-51 has been distributed under a conditional license by Professional Biological Company (a marketing subsidiary of Colorado Serum Company) since 1996.
