RB51 (For Brucellosis in cattle)
Brucella abortus RB51 is a vaccine used on female cattle. The vaccine holds worldwide importance as feed stock in many foreign countries suffer from a highly contagious bacterial disease called Brucellosis-- a bacteria that causes aborted fetuses in cattle and causes millions of dollars of annual losses to cattle industry. Brucellosis has been largely eradicated in the United States, Western Europe, Australia and New Zealand by the older vaccine, Strain 19, developed in 1946 and which RB51 is replacing.
RB51 is a relatively new vaccine. It is a strong replacement for the Brucellosis abortus Strain 19 vaccine and is being produced and marketed in the United States by the Colorado Serum Company.
vaccine has numerous
advantages over the prior vaccine (Strain 19) and is just as effective.
The advantages include:
This last point is a major breakthrough. Unlike Strain 19, RB51 can be applied multiple times to the same animal thus enhancing its immunity. Unlike Strain 19, RB51 does not cause cows to have false-positive test result on laboratory tests. RB51 vaccine can also be used on cows under the age of 12 months.
Control and elimination of this disease in cattle involves testing and vaccination of healthy cows. Vaccinating cattle to reduce the risk of transmission is essential and the absence of false positive (a characteristic of Strain RB51 vaccine not shared by Strain 19) is crucial.
RB51 has replaced Strain 19 in the United States and in foreign countries. VetTech holds the exclusive licensing rights of the vaccine from Virginia Tech and holds the trademark on the vaccine throughout Latin-America and other strategically selected countries worldwide. The RB51 vaccine has been introduced in the majority of Latin-American countries and has been recommended by the Pan American Health Organization (PAHO), a branch of the World Health Organization (WHO).
