Abstract

Despite substantial improvements, influenza vaccine production-and availability-remain suboptimal. Influenza vaccines based on mRNA may offer a solution as sequence-matched, clinical-grade material could be produced reliably and rapidly in a scalable process, allowing quick response to the emergence of pandemic strains. Here we show that mRNA vaccines induce balanced, long-lived and protective immunity to influenza A virus infections in even very young and very old mice and that the vaccine remains protective upon thermal stress. This vaccine format elicits B and T cell-dependent protection and targets multiple antigens, including the highly conserved viral nucleoprotein, indicating its usefulness as a cross-protective vaccine. In ferrets and pigs, mRNA vaccines induce immunological correlates of protection and protective effects similar to those of a licensed influenza vaccine in pigs. Thus, mRNA vaccines could address substantial medical need in the area of influenza prophylaxis and the broader realm of anti-infective vaccinology.

  • Non-replicating mRNA vaccines using exclusively unmodified nucleosides are immunogenic and capable of inducing protection against lethal rabies and influenza virus infections after intradermal vaccination in mice, rats, ferrets, and pigs.

    “Using exclusively unmodified nucleosides, we have demonstrated that non-replicating mRNA vaccines are immunogenic and capable of inducing protection against lethal rabies and influenza virus infections after intradermal vaccination (i.d.) in mice, rats, ferrets, and pigs.7,8”
  • The prior unmodified mRNA vaccine approach was specifically optimized for intradermal administration and showed lower efficacy when given by the intramuscular route.

    “This approach was specifically optimized for i.d. administration and showed lower efficacy when given by the intramuscular route (i.m.) as preferred route for prophylactic vaccination, highlighting the important role of formulation in vaccine design.”
  • Previously, i.d. administration of protamine-formulated prophylactic mRNA vaccines based on unmodified nucleosides protected mice against influenza or rabies challenge infections and induced strong humoral responses in ferrets and pigs.

    “We have previously demonstrated that i.d. administration of protamine-formulated prophylactic mRNA vaccines based on unmodified nucleosides can protect mice against influenza or rabies challenge infections and induces also in ferrets and pigs strong humoral responses.7,8”
  • Both CVnCoV and CV2CoV are based on RNActive technology and consist of non-chemically modified sequence-engineered mRNA without pseudouridine.

    “Both CVnCoV and CV2CoV are based on RNActive technology4–7 and consist of non-chemically modified sequence-engineered mRNA without pseudouridine6–12.”
  • Several studies have demonstrated the utility of mRNA as the basis of vaccines in cancer immunotherapy as well as to promote prophylactic protection from infectious diseases.

    “Several studies have demonstrated the utility of mRNA as the basis of vaccines in cancer immunotherapy as well as to promote prophylactic protection from infectious diseases (Hoerr et al, 2000; Fotin‐Mleczek et al, 2011; Petsch et al, 2012; Kubler et al, 2015; Kranz et al, 2016).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
