Abstract
Recurring influenza viruses pose an annual threat to public health. A time-saving, cost-effective and egg-independent influenza vaccine approach is important particularly when responding to an emerging pandemic. We fabricated coated, two-layer protein nanoclusters from recombinant trimeric hemagglutinin from an avian-origin H7N9 influenza A virus as an approach for vaccine development in response to an emerging pandemic. Assessment of the virus-specific immune responses and protective efficacy in mice immunized with the nanoclusters demonstrated that the vaccine candidates were highly immunogenic, able to induce protective immunity and long-lasting humoral antibody responses to this virus without the use of adjuvants. Because the advantages of the highly immunogenic coated nanoclusters also include rapid productions in an egg-independent system, this approach has great potential for influenza vaccine production not only in response to an emerging pandemic, but also as a replacement for conventional seasonal influenza vaccines.
