Overview
Brief Summary
The main aim of this clinical study is to investigate the safety and tolerability of different dose strengths of IC47 up to 6 months after the first vaccination.
A total of 32 healthy subjects (male or female) will participate in this clinical study. The subjects will be divided into 4 groups of 8 subjects each. Thirty (30) μg or 150 μg of IC47 will be administered three times in intervals of 42 days each.
