  • Vector name:
  • VO vector ID: VO_0001051
  • Description: (Okamba et al., 2010)
• Preparation: P97 recombinant replication-defective adenovirus (rAdP97c) subunit vaccine (Okamba et al., 2010).
• Immunization Route: Intramuscular injection (i.m.)

Pig Response

• Vaccination Protocol: The pigs in the rAdP97c vaccinated group, animals were vaccinated with 2 × 10^10 TCID50 of rAdP97c twice, (at days 0 and 14) by intranasal (i.n.) route (Okamba et al., 2010).
• Vaccine Immune Response Type: VO_0003057
• Challenge Protocol: The challenge was performed at day 28 after the first vaccination with 10^6 CCU of the 232 M. hyopneumoniae strain by intratracheal route (Okamba et al., 2010).
• Efficacy: The rAdP97c vaccinated pigs developed a lower amount of macroscopic lung lesions (18.5 + or - 9.6%) compared to the unvaccinated and challenged animals (45.8 + or - 11.5%). rAdP97c vaccine reduced significantly the severity of inflammatory response and the amount of M. hyopneumoniae in the respiratory tract. Furthermore, the average daily weight gain was slightly improved in the rAdP97c vaccinated pigs (0.672 + or - 0.068 kg/day) compared to the unvaccinated and challenged animals (0.568 + or - 0.104 kg/day (Okamba et al., 2010).
