Abstract

We administered Ad26, modified vaccinia Ankara vectors containing mosaic HIV-1 antigens or placebo in 26 individuals who initiated antiretroviral therapy during acute human immunodeficiency virus infection as an exploratory study to determine the safety and duration of viremic control after treatment interruption. The vaccine was safe and generated robust immune responses, but delayed time to viral rebound compared to that in placebo recipients by only several days and did not lead to viremic control after treatment interruption (clinical trial NCT02919306).
