Efficacy of a reduced-dosage PRRS MLV vaccine against a NADC34-like strain of porcine reproductive and respiratory syndrome virus by Xinyu Yan, Jiayu Liu, Fengxiong Yue, Yan Lin, Yan Li, Wensi Wu, Shan Zhao, Xiaobo Huang, Qin Zhao, Yiping Wen, Sanjie Cao, Senyan Du, Nanfang Zeng, Qigui Yan

“…We observed the changes in growth performance before and after the NADC34-like PRRSV DX strain challenge and the protective effect of different vaccine dosages through multiple assays.ResultsAfter the challenge, the piglets from the challenge control group displayed clinical signs typical of PRRSV infection, including transient fever, high viremia, mild clinical symptoms, and histopathological changes in the lungs and lymph nodes, which indicates DX is a virulent virus. Without the challenge, the average daily gain of the non-immunized group at 5 weeks after the vaccination is greater than that of the 0.01 dosage group than that of the 1 dosage group, which proved that the commercial MLV vaccine has a negative effect on the growth performance of pigs and this effect may be dose-dependent. …”
