实验进度和减肥后的挑战。(一)实验安排。叙利亚仓鼠(8 /组,4雌性,雄性)ID,免疫,平方,或博三次周0 3和6 lvΔcapB向量(ΔcapB)或rLVSΔcapB / MN(ΔcapB / MN)疫苗;挑战在星期10 104微升SARS-CoV-2 (2019 - ncov / USA-WA1/2020应变);并密切监测日常临床感染的迹象,包括减肥。一半的动物安乐死为肺病毒滴度3天邮报挑战(dpi);另一半是7点肺组织病理学dpi安乐死。(B)体重改变后的挑战。从天0到3,n = 8 /组;从天4 - 7,n = 4 /组。 Data are mean percent weight loss ± standard deviation. Mean % changes were compared among groups on each day using a repeated measure (mixed) analysis of variance model since observations on the same animal over days are correlated. P values for comparing mean changes were determined to be significant using Tukey’s adjusted criterion: *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001 (black asterisks, versus unvaccinated; red asterisks, versus vector control). Normal quantile plot examination of the residual errors and the Shapiro-Wilk test (W = 0.984) confirmed that the data followed a normal distribution, allowing the use of a parametric model.
