- Incidence and severity of treatment-emergent adverse events (safety and tolerability) [ Time Frame: Throughout the 32 weeks of the study ]Adverse events will be assessed by frequency and criteria for severity (mild, moderate or severe)
- Development of neutralizing antibodies to coxsackie B virus (immunogenicity, efficacy) [ Time Frame: Days 1, 29, and 57 and Weeks 12 and 32 ]Proportion of responders (ie, those that seroconvert or have at least a 4-fold increase in neutralizing antibody titers to any of the coxsackie B virus strains as measured by plaque reduction assay using serial serum dilutions)
- Titer of antibodies to coxsackie B virus (immunogenicity, efficacy) [ Time Frame: Days 1, 29 and 57 and weeks 12 and 32 ]Mean and peak geometric mean serum IgG titers of antibodies against any of the coxsackie B virus strains, measured by ELISA
