Pig Response

  • Persistence: A GP5 protein mutant is attenuated in piglets (Tian et al., 2009).
  • Efficacy: A GP5 protein mutant induces protection in piglets from challenge with wild type HP-PRRSV (Tian et al., 2009).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: Following a massive intratracheal challenge with the virulent IAF-Klop strain of PRRSV, DNA-vaccinated pigs were protected from generalized viraemia and the development of typical macroscopic lung lesions that were observed in unvaccinated, virus-challenged controls, as well as in pigs that were immunized with E. coli-expressed GST-ORF5 recombinant fusion protein (Pirzadeh and Dea, 1998).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: Four of six pigs in the pCA-U-optiGP5 group were devoid of visible pathological changes that were present in other vaccinated and control animals after challenge (Hou et al., 2008).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: All immunized piglets developed neutralizing antibodies at 10 weeks after primary immunization, whereas there was no detectable neutralizing antibodies in piglets immunized with pCI-ORF5. Neutralizing antibodies are considered to be important in protection against PRRSV (Jiang et al., 2006).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: After immunization and viral challenge, two of three pigs immunized with pIRESorf5/IFNgamma were protected from lung lesions that were present in other vaccinated and control animals (Cho and Dee, 2006).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: After immunization and viral challenge, one of three pigs immunized with pIRESorf5/IL-2 was protected from lung lesions that were present in other vaccinated and control animals (Xue et al., 2004).

Pig Response

  • Vaccine Immune Response Type: VO_0000286
  • Efficacy: After immunization and viral challenge, one of three pigs immunized with pIRESorf7/IL-2 was protected from lung lesions that were present in other vaccinated and control animals (Xue et al., 2004).
