流行性乙型脑炎灭活疫苗与减毒活疫苗相结合的免疫策略研究 |
| 4. | Currently , fmd vaccines are either conventionally inactivated vaccines or attenuated vaccines . both types of vaccines are not completely safe and pose some fatality risks
而传统的灭活疫苗和弱毒疫苗由于其潜在的危险性，使其应用受到很大的限制。 |
| 5. | The traditional inactivated or attenuated vaccines could not provide enough protection against these variants and wibdv . therefore , a new generation of more effective and safer vaccines is anticipated . the purpose of this study was to develop a dna vaccine against ibdv
用弱毒苗和灭活苗免疫鸡群是目前防治ibd的主要方法，但随着ibdv变异株与超强毒株的出现，免疫失败常有发生。 |
| 6. | But ib attenuated vaccine has many defects , such as the possibility of contamination of foreign and vertical transmissible pathogens , and the virulent recovery of vaccine virus . therefore , exploring the safe and efficient new vaccines has become the hotspot in the research of ib control
由于活疫苗存在外源性或垂直传播性病原污染、毒力返祖等缺陷，开发安全、有效的新型疫苗是ib控制的研究重点。 |
| 7. | Rates of hospitalization for any cause during the 180 days after vaccination were higher among the recipients of live attenuated vaccine who were 6 to 11 months of age ( 6 . 1 % ) than among the recipients of inactivated vaccine in this age group ( 2 . 6 % , p = 0 . 002 )
在6 - 11个月年龄组的儿童接受减毒活疫苗后180天内因任何原因导致的住院率的升高幅度( 6 . 1 % )较接受灭活疫苗的同一年龄组的升高率( 2 . 6 % , p = 0 . 002 )为高。 |
| 8. | Although the traditional vaccines have played active role in prevention and controlling the disease , many deficiencies exist still such as inactivated vaccine being expensive and inducing strongly response at the injected tissue , as well as the recovery of the attenuated vaccine
传统疫苗对gpv的预防和控制起到了一定的积极作用，但同时灭活苗存在生产成本高，注射局部炎症反应较强等弊端，弱毒苗又易发生毒力返强等。 |
| 9. | Prevention and cure of the derzsy ' s disease depended on vaccine and antiserum , antibodies of eggs . the vaccines includes goose embryo and duck embryo vaccines which were used 1n breed goose and goslings , and those vaccines have great effect in breeding goose , but the entire virion live vaccines and attenuated vaccines exist many deficiencies . such as preclinical infection , dissemination of virus , recovery of viru5 , etc . those proplems can be sol / ed by producing genetic engineering " asclne
目前使用的疫苗分为种鹅用和雏鹅用的鹅胚和鸭胚化疫苗，这些疫苗在实际生产中发挥巨大作用，因其为全毒苗或弱毒苗，存在着潜伏感染，排毒散毒，毒力返祖的缺陷，基因工程疫苗的研制可解决上述问题。 |
