Humoral and cell-mediated immune responses of young, seronegative children were assessed after intranasal vaccination with a cold-adapted influenza. A/HK/77 (H1N1) CR 35 recombinant virus. Vaccines shedding influenza virus experienced a rise in hemagglutinin-inhibition antibody 15 to 30 days after vaccination. Vaccinees showed low but significant lymphocyte transformation to A/USSR (H1N1) by day 8 after vaccination, which decreased to prevaccination levels at 30 to 34 days. The lymphocyte transformation response occurred before serum antibody rises were detected by hemagglutinin-inhibition assay. No change in lymphocyte responsiveness was observed after vaccination as measured by phytohemagglutinin stimulation. Lymphocytes responded to in vitro incubation with inactivated influenza (H1N1) virus by producing interferon. The interferon produced was of type I and was observed in vaccinees and nonvaccinees both before and after vaccination.
对血清反应阴性的幼儿经鼻接种冷适应流感A/HK/77(H1N1)CR 35重组病毒疫苗后,评估其体液免疫和细胞介导的免疫反应。接种流感病毒疫苗后,血凝素抑制抗体在接种后15至30天出现上升。接种者在接种后第8天对A/USSR(H1N1)表现出低但显著的淋巴细胞转化,在30至34天时降至接种前水平。淋巴细胞转化反应在通过血凝素抑制试验检测到血清抗体升高之前就已发生。通过植物血凝素刺激测量,接种疫苗后未观察到淋巴细胞反应性的变化。淋巴细胞通过产生干扰素对与灭活流感(H1N1)病毒的体外孵育产生反应。所产生的干扰素为I型,在接种者和未接种者接种前和接种后均有观察到。
