*We used 2 samples from each of 5 animals, taken >12 d apart. The earlier sample was used in the overall analysis; however, newer samples were also tested. Values related to each variant are shown for each sample, with the earlier sample above and later below. Titers are color-coded by size (stronger titers and greater decreases are shown with darker shading). B.1 indicates ancestral/wild-type virus.
