Abstract

Significance: To respond better to evolving pathogens, sudden outbreaks, and individual patient needs, a flexible, safe, and efficient vaccine platform amenable to rapid production near the point of care is required. To this end, we created a fully synthetic, single-dose, adjuvant-free nanoparticle vaccine platform wherein modified dendrimer molecules nanoencapsulate antigen-expressing replicon mRNAs. Vaccines can be multiplexed and formed with multiple antigen-expressing replicons. After a single immunization, the rapid-production, contaminant-free vaccines elicit vital CD8 + T-cell and antibody responses that fully protect against lethal exposures to several deadly pathogens, including Ebola virus, H1N1 influenza, and Toxoplasma gondii . We believe this technology may allow for rapid-response vaccines with broad efficacy that reduce the number and frequency of vaccinations, and healthcare worker burden.

  • One mRNA vaccine demonstrated efficacy in mice upon delivery of an unmodified, self-amplifying mRNA encoding the EBOV glycoprotein in a poly(amidoamine) dendrimer nanoparticle.

    “One mRNA vaccine has demonstrated efficacy in mice upon delivery of an unmodified, self-amplifying mRNA encoding the EBOV glycoprotein (Fig. 4) in a poly(amidoamine) dendrimer nanoparticle.”
  • The vaccine elicited glycoprotein-specific IgG antibodies and robust expression of IFNγ and IL-2 by CD8+ and CD4+ T cells, and two dosing regimens (two 4 μg doses or one 40 μg dose) protected mice from a lethal challenge.

    “The vaccine elicited glycoprotein-specific IgG antibodies and robust expression of IFNγ and IL-2 by CD8+ and CD4+ T cells, and two dosing regimens (two 4 μg doses or one 40 μg dose) protected mice from a lethal challenge184.”
  • Charge-altering releasable transporters and modified dendrimers can effectively deliver mRNA molecules in vitro and in vivo.

    “In addition, charge-altering releasable transporters162,247 and modified dendrimers248 can effectively deliver mRNA molecules in vitro and in vivo.”

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.
