Trial Outcomes & Findings for A Randomized, Double-blind, Placebo-controlled Study on Immunogenicity and Safety of MVA-BN (IMVAMUNE™) Smallpox Vaccine in Healthy Subjects (NCT NCT00316524)

NCT ID: NCT00316524

Last Updated: 2019-03-06

Results Overview

Seroconversion rate based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (50) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects. Percentages based on number of subjects with data available.
