Abstract
Ricin is a CDC level B biothreat. Our recombinant ricin A chain vaccine (RiVax) contains two mutations, rendering it non-toxic at high doses. Frozen or alum formulations of RiVax protected mice against ricin administered by injection, gavage or aerosol. Without alum, RiVax was safe and immunogenic in rabbits and human volunteers. For military use, the predominant target group, it would be optimal not to require a cold chain for transport and storage. We have now developed a lyophilized formulation and demonstrated stability and efficacy for at least 1 year stored refrigerated or at room temperature administered with or without alum.
摘要
蓖麻毒素是疾病预防控制中心（CDC）生物威胁级别 B 级的物质。我们的重组蓖麻毒素 A 链疫苗（RiVax）含有两种突变，使其在高剂量下也没有毒性。冷冻或明矾制剂的 RiVax 可保护小鼠免受注射、灌胃或气溶胶形式给予的蓖麻毒素的侵害。没有明矾，RiVax 在兔子和人类志愿者中是安全且具有免疫原性的。对于军队等主要目标人群，疫苗在运输和储存过程中无需冷链是最佳选择。我们现已开发出一种冻干制剂，并证明其在冷藏或室温下储存至少 1 年的稳定性和有效性，同时可与或不与明矾一起使用。
