Avian influenza remains a major pandemic threat. In response to this threat, the objective of our work was the development of live attenuated reassortant influenza vaccine (LAIV) against recent isolates of potentially pandemic H7N9 influenza viruses which may cause serious and fatal disease in humans. Two H7N9 LAIV candidates were generated by using two different approaches: classical reassortment in eggs and reverse genetics. The collected data indicate that regardless of the approach both H7N9 LAIV candidates acquired attenuated properties - temperature sensitivity and cold-adaptation.
