Immune imprinting narrows the vaccine recall response towards dominant epitopes but protection against rapidly evolving viruses is enhanced if the breadth of responses is preserved. Here authors show in a ferret model that introducing optimized antigenic variation between prime and boost vaccines diversify the targeted epitopes and thus broadens immunity in a ferret model of influenza vaccination.
