From: PCV2 vaccination induces IFN-γ/TNF-α co-producing T cells with a potential role in protection
Time schedule of the animal experiment. Piglets were weighed after arrival and subsequently two more times in the course of the experiment. PCV2 vaccination was performed on study day 0. Piglets were inoculated with a PCV2a isolate 24 days post vaccination (dpv). Serum samples were taken twice before challenge (−4, 24 dpv) and 5 times thereafter (28, 35, 42, 49, 56 dpv). Heparinized blood samples for the isolation of PBMCs were taken on the day of vaccination, on day 24 post vaccination, 42 dpv and at the end of the study (56 dpv).
