Tehran - Iran Veterinary Organization (IVO) has given permission to the Razi Vaccine and Serum Research Institute to begin mass production of its "Bivalent Live Newcastle and Infectious Bronchitis Vaccine (Clone12IR H-120)".

The head of the Bronchitis and Encephalomyelitis Vaccines Production Laboratory said the mass production of the vaccine will help reduce reliance on imported vaccines and save valuable foreign currency.

“The new bivalent vaccine will simplify vaccination procedures for farmers by reducing the need for multiple vaccinations, leading to lower flock mortality rates and a significant reduction in both time and costs associated with vaccination programs,” Shahin Masoudi noted.

The Clone12IR strain is a Newcastle Lentogenic virus known for its strong protective effects on chickens, regardless of maternal antibodies, and offers the benefits of both B1 and Lasota vaccines, including minimal side effects and robust immune responses.
