The Virulence of the Strain was Stable But not Strong
The bovine A19 vaccine strain (CVCC70202) was developed by Buck in 1923. It has high genetic stability and no need to worry about the return of virulence powerful.

Advanced Technology High Antigen Content
Using unique ventilation culture technology and adding new protective agents, the vaccine bacteria have strong vitality and high antigen content, ensuring that the number of live bacteria per head of vaccine is not less than 60 billion CFU during the effective period.

Live Vaccine for Cattle Brucellosis
The A19 vaccine strain is a attenuated strain of Brucellosis bovis, which has stronger and higher specificity against brucellosis bovis infection.

Special Diluents Work Better
The vaccine is diluted with a special diluent, which can induce cattle to produce high levels of antibodies with a protection period of up to 72 months.

Recommended Immunization Program
Calves: The first immunization should be given at 3-8 months of age, and the immunization should be strengthened once 1-2 months before breeding.

Vaccine Usage Method
Subcutaneous injection. 1 dose per cow for the first vaccination; appropriate reduction for booster vaccination.

Precautions for Use
1. Cannot be used on pregnant and lactating cattle.
2. Three days before and after immunization, stop using any antibacterial drugs or additive feed.
3. The vaccine was transported refrigerated at -15°C and stored away from light.
