Immunogenicity and protection of recombinant self-assembling ferritin-hemagglutinin nanoparticle influenza vaccine in mice.

Purpose: Influenza virus remains a serious burden to global public health. Current influenza vaccine fails to provide impeccable protection efficacy to the annual seasonal influenza and cannot offer a timely response to potential pandemic influenza. It is necessary to develop next generation influenza vaccines to solve the current dilemma.

An mRNA-based broad-spectrum vaccine candidate confers cross-protection against heterosubtypic influenza A viruses.

Influenza virus is a prominent cause of respiratory illness in humans. Current influenza vaccines offer strain-specific immunity, while provide limited protection against drifted strains. Broad-spectrum influenza vaccines can induce broad and long-term immunity, and thus are regarded as a future direction for the development of next-generation influenza vaccines.
