Abstract

Vaccine-induced protection of chimpanzees against laboratory-adapted and syncytium-inducing, multiply passaged primary human immunodeficiency virus type 1 (HIV-1) isolates, but not against non-syncytium-inducing, minimally passaged ones, has been demonstrated. Following challenge with such an isolate, HIV-15016, we obtained complete protection in one of three chimpanzees previously protected against low- and high-dose HIV-1SF2 exposures after immunization with an adenovirus-HIV-1MN gp160 priming-HIV-1SF2 gp120 boosting regimen. At challenge, the protected chimpanzee exhibited broad humoral immunity, including neutralizing antibody activity. These results demonstrate the potential of this combination vaccine strategy and suggest that vaccine protection against an HIV isolate relevant to infection of people is feasible.

摘要

疫苗诱导的针对实验室适应的、诱导合胞体的、多次传代的1型人类免疫缺陷病毒(HIV-1)分离株的黑猩猩保护作用已得到证实,但对非诱导合胞体的、传代极少的分离株则无保护作用。在用这样一种分离株HIV-15016进行攻击后,我们在三只先前经腺病毒-HIV-1MN gp160初免-HIV-1SF2 gp120加强免疫方案免疫后对低剂量和高剂量HIV-1SF2暴露有保护作用的黑猩猩中的一只身上获得了完全保护。在攻击时,受保护的黑猩猩表现出广泛的体液免疫,包括中和抗体活性。这些结果证明了这种联合疫苗策略的潜力,并表明针对与人类感染相关的HIV分离株的疫苗保护是可行的。
