Det betyder, at et gen fra to forskellige hesteinfluenzastammer (A/ equi- 2/ Ohio/ 03 og A/ equi- 2/ Newmarket/ 2/ 93) blev indsat i hver sin levende canarypox vektorvirus, der dermed blev i stand til at producere dele af disse influenzastammer (specifikke proteiner).
This means that a gene from two different equine influenza strains (A/ equi-2/ Ohio/ 03 and A/ equi- 2/ Newmarket/ 2/ 93) was inserted in two live canary pox vector viruses respectively which were made capable to produce parts of these influenza strains (specific proteins).
