Newcastle Disease viral component of Gampasol® is cultured on embryonated SPF eggs, and Infectious Bursal Disease viral component is cultured in vitro in cell culture. Subsequently, they are inactivated by using Formalin. By this method, viruses lose their infectivity while retaining immunity-inducing capabilities. Then, inactivated viruses are mixed and added to the oil adjuvant. Finally, emulsiﬁcation takes place for the preparation of ﬁnal vaccine. This bivalent vaccine contains two major components:
l- Newcastle Disease Virus strainV4
2- Infectious Bursal Disease Virus (Gumboro Virus)
The vaccine content:
Each dose contains:
Newcastle Disease Virus strain V4 108.5 EID50 titrated before inactivation.
Infectious Bursal Disease Virus 106 TCID50 titrated before inactivation.
Gampasol® is a bivalent vaccine for the prevention of Newcastle Disease and Infectious Bursal Disease.
