Reactogenicity informs vaccine safety, and may influence vaccine uptake. We evaluated factors associated with reactogenicity in HVTN 702, a typical HIV vaccine efficacy trial with multiple doses and products.
HVTN 702, a phase 2b/3 double-blind placebo-controlled trial, randomized 5404 African participants aged 18-35 years without HIV to placebo, or ALVAC-HIV (vCP2438) at months 0, 1 and ALVAC-HIV (vCP2438) + Bivalent Subtype C gp120/MF59 at months 3, 6, 12 and 18. Using multivariate logistic regression, we evaluated associations between reactogenicity with clinical, sociodemographic and laboratory variables.
More vaccine than placebo-recipients reported local symptoms (all p < 0.001), arthralgia (p = 0.008), chills (p = 0.012) and myalgia (p < 0.001). Reactogenicity was associated with female sex at birth (OR = 2.50, OR = 1.81, both p < 0.001) and geographic region. Amongst vaccine-recipients, each year of age was associated with 3 % increase in reactogenicity (OR = 1.03, p = 0.002).
Vaccine receipt, female sex at birth, older age, and region may affect reactogenicity.
疫苗接种反应性可反映疫苗安全性,可能会影响疫苗接种率。我们评估了 HVTN 702 中与疫苗接种反应性相关的因素,这是一项具有多剂次和多种产品的典型 HIV 疫苗功效试验。
HVTN 702 是一项 2b/3 期、双盲、安慰剂对照试验,将 5404 名无 HIV 的 18-35 岁非洲参与者随机分为安慰剂组或 ALVAC-HIV(vCP2438)组,于 0、1 月和 ALVAC-HIV(vCP2438)+二价 C 型 gp120/MF59 组,于 3、6、12 和 18 月。我们采用多变量逻辑回归,评估了疫苗接种反应性与临床、社会人口学和实验室变量之间的关系。
与安慰剂组相比,更多的疫苗接种者报告了局部症状(均 p<0.001)、关节痛(p=0.008)、寒战(p=0.012)和肌痛(p<0.001)。疫苗接种反应性与出生时的女性性别(OR=2.50,OR=1.81,均 p<0.001)和地理位置有关。在疫苗接种者中,每增加一岁,反应性增加 3%(OR=1.03,p=0.002)。
疫苗接种、出生时的女性性别、年龄较大和地理位置可能会影响疫苗接种反应性。
