Expressed HA/Virus	HA Titre
CVV-M	<2	<2	<2
cHA-C	<2	<2	<2
cHA-E	<2	<2	<2
Lab H5N2 (A/pheasant/New Jersey/1355/1998) virus isolate [PNJ]	128	128	128
PBS	<2	<2	<2

Note: Expressed cHAs and M (30 µg/mL) were challenged with 1.0% turkey red cells in the haemagglutination assay. Experiment was controlled with the expressed candidate vaccine HA (CVV-M), PBS and a laboratory H5N2 virus isolate (PNJ).
