Rate this question:
Low concentrations of cross-reacting antibodies from exposure to serotype 1 were not sufficient to neutralize virus of serotype 2
Antibodies against serotype 1 were present but did not cross-react with virus of serotype 2
Antibodies against serotype 1 cross-reacted with virus of serotype 2 to opsonize virus for greater uptake by macrophages
Antibodies against serotype 1 cross-reacted with virus of serotype 2 to block its phagocytosis by macrophages
