Comparisons are presented in Table 8 . Again, there were anomalies with mAbs neutralizing isolates which were not neutralized by the corresponding plasma and vice versa. Similarly, the mAbs showed a reduced range of neutralization relative to their corresponding plasma. Plasma from the 242315-HJ patient is very effective against the three tier 1 strains and also against five out of 11 tier 2 strains. In contrast, the corresponding HJ16 mAb is not able to neutralize the tier 1 strains and although effective against six out of 11 tier 2 strains, these are not always the same isolates as neutralized by the plasma. Plasma from the 314994-HGN patient is able to neutralize all tier 1 strains as well as four tier 2 strains while the HGN194 mAb is also able to neutralize the tier 1 strains and three out of 11 tier 2 strains. However, again, these are not always the same strains that are neutralized by the plasma. Plasma from the HK patient is able to potently neutralize the three tier 1 strains but none of the tier 2
