Abstract
En 中文
This article describes the protocol of the PregInPoxVac vaccine trial, evaluating the safety and immunogenicity of two MVA-BN vaccination regimens (full-dose and half- dose) administered subcutaneously with a 28-day interval in infants aged 4 to <24 months old. Non-inferiority of the full dose and half dose regimens will be compared to adults receiving a full dose regimen as part of the POX-MVA-045 study (ClinicalTrials.gov Identifier: NCT06549530 ). The PregInPoxVac study is being conducted in Boende, Tshuapa Province, Democratic Republic of the Congo (DRC), a mpox-endemic area; the POX-MVA-045 study is being conducted in Kinshasa, DRC, and Entebbe, Uganda. This is a randomized, double-blind, phase 3 trial assessing two dosing regimens in infants, with immunogenicity and safety compared to a predefined adult reference dataset.
