Abstract

A variety of platforms are being explored for the development of vaccines for pandemic influenza. Observations that traditional inactivated subvirion vaccines and live-attenuated vaccines against H5 and some H7 influenza viruses were poorly immunogenic spurred efforts to evaluate new approaches, including whole virus vaccines, higher doses of antigen, addition of adjuvants and combinations of different vaccine modalities in heterologous prime-boost regimens to potentiate immune responses. Results from clinical trials of prime-boost regimens have been very promising. Further studies are needed to determine optimal combinations of platforms, intervals between doses of vaccines and the logistics of deployment in pre-pandemic and early pandemic settings.
