Summary

The purpose of this study is to assess the safety, reactogenicity and immune response of the candidate CMV recombinant protein subunit (CMVsu) vaccine consisting of a combination of glycoproteins B (gB) and pentamer antigens adjuvanted, regardless of baseline CMV sero-status. This FTiH study is conducted in healthy adults 18 to 50 years of age, in which the 4 dose levels of the vaccine are administered in a step-wise dose escalation manner, based upon safety adjudication.
