Chicken Response

• Vaccine Immune Response Type: VO_0000286
• Immune Response: A significant increase in serum antibody levels was observed in chickens vaccinated with the fusion DNA vaccine. Additionally, the lymphocyte proliferation (SI value) and the levels of IFN-γ were both higher in chickens immunized with the fusion DNA vaccine than in those vaccinated with monovalent DNA vaccines (P<0.05) (Gong et al., 2013).
• Efficacy: Protection provided by the fusion DNA vaccine was superior to that provided by monovalent DNA vaccines after challenging with the avian P. multocida strain CVCC474. The protective efficacy in chickens immunized three times with the fusion DNA vaccine was equivalent to the protective efficacy in chickens vaccinated once with the attenuated live vaccine (Gong et al., 2013).
