Smallpox Clinical Trial
Official title:
Take Evaluation and Safety of Smallpox Vaccine (LISTER Strain) in Naïve Healthy Adults.
Primary Objective:
To estimate the smallpox vaccination take rate in healthy young adults not previously
vaccinated with a smallpox vaccine.
Secondary Objectives:
To describe antibody response to vaccination and evaluate the take for each subject at
various timepoints for each batch and pooled batches and to evaluate local signs, symptoms,
and overall safety in healthy young adults not previously vaccinated with a smallpox
vaccine.
