  This study evaluated the efficacy of PCV2a and PCV2d vaccines against a PCV2 challenge. Three-week-old, cesarean-derived, colostrum-deprived pigs were blocked by litter and randomized to treatment group. Pigs received a single 2 mL intramuscular dose of either placebo (PLAC, n=50), PCV2a vaccine (PCV2aV, n=25), or PCV2d vaccine (PCV2dV, n=25) on D0 and were challenged with a PCV2d isolate on D28. Prior to challenge, a naturally occurring PCV2a infection was identified. Both vaccines similarly prevented lymphoid tissue lesions, mortality and clinical signs of PCVAD while PLAC pigs were severely affected. Viremia was significantly reduced 7, 14, 21, and 28 days post-c.. View more»
