Histopathological analysis of SARS-CoV-2 VOC infection in the lungs of prime-boost HD-Ad-FS vaccinated hamsters. (A-C) Detection of SARS-CoV-2 variant RNA (Beta, A; Delta, B; Omicron, C) in lung sections with RNA in situ hybridization at 4 dpi. (D-F) The presence of SARS-CoV-2 variant RNA (Beta, d; Delta, e; Omicron, f) in lung sections with RNA in situ hybridization at 14 dpi. Continuous lung sections were used for H&E staining (3rd, 6th, and 9th rows). Scale bars = 200 (grey bar) or 1000 (black bar) µm. Images are representatives of n=2 per group. Data represent one independent animal experiment with indicated biological replicates.
