There was no protection in group 1(Transfer factor+3 times inactivated antigen)and group 2(3 times activated antigen +3 times inactivated antigen). ? 试验3组(活+3倍灭活苗组)、试验4组(活+佑蓝宝)和试验5组(活+3倍佑蓝宝组)可对强毒攻击保护,说明单独免疫灭活疫苗不能抵 抗强毒的攻击,试验3组(未添加佐剂)保护率为91%(10/11)能够很好地抵抗强毒的攻击,试验

4、5组保护率为100%(11/11)是目前预 防本病最理想的选择. ? There were protection against the challenge in group

3 (Live vaccine +3 times inactivated antigen ) ,group 4( Live vaccine+You LanBao) and group

5 (Live vaccine+3 times You LanBao).It indicates the inactivated vaccine alone could not resist the virulent challenge. The protection rate in group

3 without adjuvant was 91%(10/11).It can resist the highly virulent challenge. The protection rate in group

4 and

5 was 100%(11/11) and is the best choice for preventing and controlling. 1.2 试验结果 Test result 佑本疫苗 至纯至美 2018/12/4 ZFX版权
