		OK118		OK450
		Preimmunization	Postimmunization	Preimmunization	Postimmunization
1	OK118b	<32	256	<32	256
2	OK118b	<32	128	<32	128

^aNeutralization antibody titers in sera of mice immunized with CHRV (OK118 and OK450 strains) and human group A rotaviruses (Wa and Hochi strains) were determined against OK118 or OK450. 

^bFor the immunization viral antigens purified from culture fluid were used. 

^cFor the immunization viral antigens directly purified from feces were used.
