| 中文摘要: |
| 将 319名受隐性感染机会较少的 5～ 18月龄的婴幼儿分为两组,分别接种乙型脑炎 (乙脑 )灭活疫苗和减毒活疫苗。经间接免疫荧光法检测其血清抗体发现,免疫前血清抗体仅有 3.76%阳性。基础免疫后,两种疫苗的抗体阳性率分别增加至 59.56%和 56.0 8%,但尚不能达到保护性水平。 1年后加强注射 1针,1个月后阳性率分别增加至 94.62 %和 98.2 1%,GMT也明显增加,半年后,阳性率改变为 72.34 %和 94.74 %。减毒活疫苗在加强免疫后的免疫效果及持久性明显高于灭活疫苗。根据观察结果认为,乙脑灭活疫苗免疫,应基础免疫两针,间隔 7～ 10天,第二年加强免疫1针之后,间隔 1年再加强 1针。减毒活疫苗基础免疫 1针,第二年加强 1针,经 4～ 5年后再加强注射。由于减毒活疫苗高的免疫效果,较少的接种次数以及较高的安全性,适宜于广大地区推广应用。 |

| 319 infants aged 5-18 months were divided in to 2 groups and immunized with Japanese encephalitis virus inactivated vaccine and live attenuated vaccine respec tively. Under thedetection of serum antibody, a 3. 76% serum antibody positive rate was revealed before the immunization. However, after the basic immuni zation the serum positive rates of the two vaccines reached 59. 56% a nd 56. 08% respectively but still under the protective level. The infants were then given booster injection one year later. The serum positive rates reached 94. 62% and 98. 21% respectively1 month later. When six months after the booster immunization, the positiverates were 72. 34%and 94. 74% r espectively. According to the result, the following immunization order was recommend.For inactivated vaccine: 2 injections are given with an interval of 7-10 days for basic immunization and boo ster immunization be given in the second and third years. For live attenuated vaccine:one injection is given for basic immunization then booster dosebe given in the second yea r and4-5 years later. |
