Pfizer launches new leptospira vaccine for cows

Pfizer Animal Health has introduced a new vaccine, Bovi-Shield GOLD® HB, that combines five-way viral protection with the prevention of Leptospira borgpetersenii serovar Hardjo type Hardjo-bovis, commonly known as Lepto hardjo-bovis.

Lepto hardjo-bovis is the most prevalent strain of leptospira in US cowherds.

A recent study found 42 percent of beef herds infected, while another study also suggested 59 percent of US dairy herds may be infected with leptospira.

Lepto hardjo-bovis may cause poor reproductive performance, early embryonic death, delayed breeding, abortions, weak or stillborn calves and unexplained infertility.

Bovi-Shield GOLD HB also provides protection against five major viral pathogens including IBR, PI3, BRSV and BVD Types 1 and 2, and the vaccine can be administered intramuscularly or subcutaneously.

Bovi-Shield GOLD HB offers at least 365 days of immunity for IBR abortions, BVD Types 1 and 2 persistent infection, Lepto hardjo-bovis infection, and Lepto hardjo-bovis urinary shedding and kidney colonisation.
