摘要: Summary Vaccination at either 1, 7 or 15 days of age with an attenuated strain (vaccinal 1–65 PV) infectious bursal disease (IBD) virus did not suppress the immune response to Newcastle vaccination. These results suggest that vaccination chickens against IBD vaccinal PV does damage bird's lymphoid tissues and consequently its immunological capabilities other diseases.
