Abstract [en]

Respiratory syncytial virus (RSV) is a major pathogen causing severe upper and lower respiratory disease in infants and in elderly worldwide. ccording to WHO, an RSV vaccine is urgently needed. Here, we describe the design of various types of subunit vaccine concepts based on molecular engineering aimed to deliver RSV antigens. Gene segment encoding parts of the conserved central region of the RSV G protein (G2Na) were prepared for various expression and delivery formats: (1) prokaryotically expressed and purifi ed G2Na alone or fused to different carrier proteins, one of them, namely, BBG2Na (Alum), has reached clinical trials in the elderly; (2) G protein-derived antigens surface displayed on lived vectors (non pathogenic bacteria) and (3) nucleic acid vectors. These subunit vaccines were administered with or without adjuvant in rodents and in non-human primates by different routes (parenteral or mucosal). We summarise and compare immunogenicity, protective effi cacy and safety conferred by each immunisation format in RSV experimental animal models. Among these, G2Na proved to be the most promising component for an RSV subunit vaccine.
