Abstract
Chimaera was a monster in ancient Greek mythology combining elements from different animal species in its body. Modern molecular biology enabled the generation of harmless but useful chimaeras consisting of elements from different nonrelated viruses. The objective is that the resulting chimaeras form highly immunogenic virus-like particles (VLPs). Such chimaeric VLPs can be used as highly efficient carriers for sequential and conformational B cell epitopes and T cell epitopes. Most VLPs are readily produced in heterologous hosts and are easy to purify. This article deals with various systems of VLPs described in this topical issue of Intervirology and makes comparisons with chimaeric replication-competent viruses, recombinant virus vectors expressing foreign proteins, and DNA vaccines.
