Heamagglutination tests were applied to detect virus in allantoic fluid of chicken embryos which were infected by b95 gathered from the vaccinated chickens " cloacal and oral cavity. the results show that the virus may be detected from 2 days to 11 days after the chicken being vaccinated. the hi antibodies were measured by heamagglutination inhibition tests. there is no significant difference between the immunized and the control chickens which were fed in one case. chickens were immunized with b95 by different immunization meathods or with different vaccines by the same meathod. lt is demonstrated that eyedrop, drinking water, spray or muscle injection all can stimulate good effects, but eyedrop and spray seem to be the best meathods. b95 immunized chicken have relatively higher hi titers and it also can last for a longer time than others
