From: Impact of maternally derived immunity on piglets’ immune response and protection against porcine circovirus type 2 (PCV2) after vaccination against PCV2 at different age

Course of the serologic response to PCV2 (Mean ± STD anti-PCV2 ELISA antibodies) according to the levels of maternal derived antibodies (MDA) at vaccination and PCV2 infection (viremia) occurred at 20 weeks of age. Overall, the animals of the 3 replicates were divided based on a low (≤0.9) or high (≥1.2) S/P value at 4 weeks of age when vaccinated animals were inoculated with the vaccine (“HIGH S/P vac” and “LOW S/P vac” groups) while unvaccinated animals were inoculated with the adjuvant alone (“HIGH S/P NV” and “LOW S/P NV” groups)
