高剂量流感疫苗更好地保护艾滋病毒感染的成年人
(健康日)-HIV感染的成年人在用高剂量的流感三价疫苗免疫的情况下,与标准剂量相比,与标准剂量相比,达到了较高的Seloprotiect率,根据1月1日发表的一项研究内科。
Noah McKittrick, M.D., from University of Pennsylvania in Philadelphia, and colleagues randomly assigned 190 HIV-infected persons (older than 18 years) to receive either a standard dose (15 mcg of antigen per strain; 93 participants) or a high dose (60 mcg/strain; 97 participants) of the influenza trivalent vaccine. The rate of seroprotection was assessed, defined as antibody titers of 1:40 or greater on the hemagglutination inhibition assay 21 to 28 days after vaccination. Seroconversion, defined as a greater than four-fold increase in antibody titers, and the geometric mean antibody titer were also assessed.
研究人员发现,在高剂量组中,H1N1(96与87%的速度为87%; P = 0.029),H3N2(96与92%; P = 0.32),和流感B.(91与80%; p = 0.030)菌株。标准化和高剂量疫苗均耐受良好,最常见不良事件肌节(19%),萎靡不振(14%)和局部疼痛(10%)。
“这项研究的影响对于艾滋病毒阳性人口的未来疫苗接种努力非常重要,”作者写道。“本研究表明,大量的艾滋病毒感染患者可能无法获得足够的保护标准流感疫苗。“
