[Retracted] Construction and Immunogenicity of DNA Vaccines Encoding Fusion Protein of Porcine IFN-1 and GP5 Gene of Porcine Reproductive and Respiratory Syndrome Virus
Figure 5
The PRRSV-specific neutralizing antibodies in mice immunized with different DNA constructs. Mice were immunized as in Figure 4. Serum samples were collected at 2, 4, and 6 weeks after primary immunization to determine neutralizing antibody. Data represent the mean and S.D. for 7 mice per group.
