Cells infected were infected with each virus alone or virus mixed with blood serum from vaccinated persons. The cells stain blue but when the cells are killed by virus you see a hole (white) in the cell sheet. In the figure you see that the original 2020 SARS-CoV-2 is completely killed by the blood of vaccinated people but the Omicron virus killing is much reduced. (IMAGE)
