Lack of production of hH5N1 HA233-specific antibodies by an inactivated rH5N1 virus.
BALB/c mice were injected i.p. with UV-inactivated rH5N1 virus, a complex of the UV-inactivated rH5N1 virus encapsulated in DOPE:CHEMS, or a complex of the UV-inactivated rH5N1 virus and Lipoplex(O) on three occasions. The sera were collected, and the titers of rH5N1 virus-specific total IgG (A) and hH5N1 HA233-specific total IgG (B) were measured by ELISA.
