The preclinical research studied Infectimune™, PDS Biotech’s novel investigational infectious disease immune activating platform, and demonstrated the technology’s potency in eliciting CD4 T cells. The studies focused on comparing Infectimune™ induced immune responses following primary vaccination against influenza with immune responses induced by leading vaccine adjuvants. This publication follows a recent article in Viruses highlighting the ability of Infectimune™ to generate a broad immune response against viruses, including SARS-CoV-2 and multiple strains of influenza. The paper, titled, “R-DOTAP cationic lipid nanoparticles outperform squalene-based adjuvant systems in elicitation of CD4 T cells after recombinant influenza hemagglutinin vaccination,” reported findings from a preclinical study investigating the ability of Infectimune™ (R-DOTAP) to promote CD4 T cell responses to vaccination with recombinant influenza protein. Infectimune™ was compared to AddaVax™, which is analogous to commercial adjuvant MF59®, and AddaVax™ combined with CpG, a commercial adjuvant, using HA-B as the influenza vaccine antigen. Results from the study concluded that Infectimune™ dramatically enhanced CD4 T cell responses to recombinant HA-B proteins relative to AddaVax™ and AddaVax™ plus CpG. Further, the Infectimune™ elicited CD4 T cells displayed abundant Interferon (IFN)-gamma and Interleukin (IL)-2 production that are critical for protective immunity. CD4 T cells are documented to present multiple functions including CD8 T cell expansion and antibody responses as well as direct anti-viral effects and potentiation of antigen presenting function to enhance protection against viral infection. “Influenza remains c...
