At day 8 postchallenge, mean titers remained consistent at 151
At day 8 postchallenge, mean titers remained consistent at 151.7 (95% CI, 124.7 to 184.6). significantly better than they blocked GII.2.2002, GII.2.2008, and GII.2.2010, suggesting that blockade epitopes within the GII.2 strains have evolved in the past decade. To potentially map these epitope changes, we developed mouse monoclonal antibodies (MAbs) against GII.2.1976 VLPs and compared…
