Conventional influenza vaccines are designed to stimulate neutralizing antibodies against immunodominant but highly variable hemagglutinin antigens. Inherent limitations include suboptimal protection against rapidly changing seasonal influenza viruses and a lack of protection against antigenically novel pandemic influenza. New technologies for developing influenza vaccines that induce more broadly protective and durable immunity are a growing area of research and focus on a variety of approaches, including targeting conserved antigens and stimulating cross-reactive T cell responses. This review highlights a new effort to track the development of universal influenza vaccine technologies. The Universal Influenza Vaccine Technology Landscape is intended to provide stakeholders and funders with a common source of information to monitor research progress and identify opportunities for informed investments and collaboration.

Influenza A Virus H7 nanobody recognizes a conserved immunodominant epitope on hemagglutinin head and confers heterosubtypic protection.

Influenza remains a persistent global health challenge, largely due to the virus' continuous antigenic drift and occasional shift, which impede the development of a universal vaccine. To address this, the identification of broadly neutralizing antibodies and their epitopes is crucial. Nanobodies, with their unique characteristics and binding capacity, offer a promising avenue to identify such epitopes.

In a Phase 2a, double-blind, placebo-controlled study including healthy participants aged 18-55 years, OVX836, a nucleoprotein (NP)-based candidate vaccine, previously showed a good safety profile, a robust immune response (both humoral and cellular) and a preliminary signal of protection (VE = 84%) against PCR-confirmed symptomatic influenza after a single intramuscular dose of 180 µg, 300 µg or 480 µg. : Using the same methodology, we confirmed the good safety and strong immunogenicity of OVX836 at the same doses in older adults (≥65 years), a key target population for influenza vaccination. : Significant humoral (anti-NP IgG) and cellular (interferon gamma (IFNγ) spot-forming cells per million peripheral blood mononuclear cells and specific CD4 IFNγ T-cells) immune responses were observed at the three dose levels, without clear dose-response relationship.

Standard-of-care influenza vaccines contain antigens that are typically derived from components of wild type (WT) influenza viruses. Often, these antigens elicit strain-specific immune responses and are susceptible to mismatch in seasons where antigenic drift is prevalent. Thanks to advances in viral surveillance and sequencing, influenza vaccine antigens can now be optimized using computationally derived methodologies and algorithms to enhance their immunogenicity.
