Therefore,pTL-8/AMA-l combined with pUHS6-l is a good regulable DNA vaccine candidate against Plasmodium falciparum. The constructionof this system lays the foundation for future research to explore the mechanism of DNA immunizaiton and regulate the antigen expression to reduce side effects of DNA vaccines.

该系统的建立将对进一步深入研究DNA疫苗的免疫机制和调控基因表达、减少不良免疫反应以及进行可精确调控的基因治疗打下一定的基础

Authorities confessed that diphtheria may occur in vaccinated individuals, and noted that the permanence of immunity induced by the toxoid…is open to question.

权威机构公开承认白喉也许在接种了疫苗的个体中也会发生，并且指出这种类毒素诱发的免疫的永久性…是可疑的。

Objective To screen the protective antigen of G.intestinalis and set the foundation for immune reseach of vaccine. Methods The trophozoite antigens were obtained with in vitro culture system of Giardia lamblia Stile. After further separation, purification and activity verification, the antigens were used to immunize the BALB/C mice divided into different groups,then indexes associated with immunity were determined. Through challenge infection, the most protective antigenic component of G.intestinalis were selected based on its anti-infection ability.

目的 筛选蓝氏贾第鞭毛虫的保护性抗原，免疫疫苗的研制奠定基础方法利用已建立的蓝氏贾第鞭毛虫滋养体体外培养系统，获取滋养体抗原，并进步分离、纯化、活性鉴定；然后分组免疫小鼠，检测相关免疫指标；再行攻击感染试验，视其抗感染能力，筛选出保护性强的抗原组分。

The antigenic reservoir produced a protective rate as high as 80%, which provides a way for developing new vaccine of Trypanosome evansi.

该抗原库的最佳免疫保护率达到 80%以上，它的建立为伊氏锥虫疫苗的研制开辟了一条新的途径。

If cells were truly understood, that process might speed up to the point where the vaccine was ready in time to do something useful.

如果我们对细胞有彻底的了解，疫苗的研制过程也许会加速，在我们需要的时候能及时的发挥作用。

It indicated that more economic benefits would be gained if mass HA vaccination strategy was used. Vaccinee of choice was those at ages of 15 to 29 years. HA vaccination after antibody screening in the population aged over 25 years would be more ecomonic than the direct use.

开展甲型肝炎疫苗的大规模人群接种具有较高的经济效益，15-29岁的人群为接种的首选对象，对25岁以上人群接种前先进行抗体筛选能节省成本。

The move to broaden the age means older women can also now access the vaccine but it is not free, and Dr Wain says those interested should talk with their GP.

疫苗的适用范围扩大到中年的妇女，但是并不是免费的，有意者请咨询你的家庭医生。

The number of CD〓 and CD〓 lymphocytes subpopulation and IgA, IgM, IgG antibody-producing cells, the ratios of CD〓 and CD〓 T-cell in the cecal tonsils and Harderian glands, the content of IgA, IgM, IgG in tear, tracheal fluid, intestinal fluid and bile of CIAV-infected chicks vaccinated with ND vaccine were significantly decreased compared with vaccinated control chicks 7～28 days PV.

CIAV感染雏鸡ND免疫后28天内，哈德尔腺、盲肠扁桃体以及泪液、气管液、肠液、胆汁的上述各项免疫学指标，均不同程度的明显低于未感染CIAV的ND免疫雏鸡，表明CIAV感染雏鸡呼吸道和消化道局部粘膜对ND疫苗的细胞和体液免疫应答机能下降。

The N gene protein was expressed in the CHO cells proved by IFA. The N gene was transcripted as proved with RT-PCR. CHO/CDV-N cell strain was constructed, which provided evidence for research of CDV serumal detection and gene vaccine.

然后通过磷酸钙共沉淀法转染CHO-K1细胞，通过潮霉素筛选得到阳性克隆，间接免疫荧光实验鉴定N基因在CHO细胞中的表达，并用RT-PCR方法从转录水平证实N基因在CHO-K1细胞中的表达，最终建立了CHO/ CDV-N细胞株，为犬瘟热病毒的血清学检测和基因疫苗的研制奠定了基础。

The researchers say the number of new infections could drop below one in one thousand people in the unvaccinated population.

研究人员说，在未接种疫苗的人群中新感染的病例减少了1000人，这就是有名的&人群保护&的结果。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
