Abstract

A cytomegalovirus (CMV) vaccine that is effective at preventing congenital infection and reducing CMV disease in transplant patients remains a high priority as no approved vaccines exist. While the precise correlates of protection are unknown, neutralizing antibodies and antigen-specific T cells have been implicated in controlling infection. We demonstrate that the immunization of mice and nonhuman primates (NHPs) with lipid nanoparticles (LNP) encapsulating modified mRNA encoding CMV glycoproteins gB and pentameric complex (PC) elicit potent and durable neutralizing antibody titers. Since the protective correlates in pregnant women and transplant recipients may differ, we developed an additional mRNA vaccine expressing the immunodominant CMV T cell antigen pp65. Administration of pp65 vaccine with PC and gB elicited robust multi-antigenic T cell responses in mice. Our data demonstrate that mRNA/LNP is a versatile platform that enables the development of vaccination strategies that could prevent CMV infection and consequent disease in different target populations.

  • Multivalent influenza and cytomegalovirus mRNA vaccines have shown that integration of multiple antigens can lead to robust nAb responses in pre-clinical models which correlate with protection for multiple vaccines.

    “Multivalent influenza21 and cytomegalovirus22 mRNA vaccines have shown that integration of multiple antigens can lead to robust nAb responses in pre-clinical models which correlate with protection for multiple vaccines18,23.”
  • mRNA vaccines can combine different antigen mRNAs; for example, six separate mRNAs have been incorporated in a cytomegalovirus vaccine, five of which encode a single pentameric antigen and one encodes a glycoprotein antigen.

    “Second, mRNA vaccines can combine different antigen mRNAs; for example, six separate mRNAs have been incorporated in a cytomegalovirus vaccine, five of which encode a single pentameric antigen and one encodes a glycoprotein antigen185.”

  • A multiple-antigenic mRNA vaccine encoding the five CMV pentameric complex subunits together with CMV glycoprotein gB induced potent and durable neutralizing antibody titers in immunized mice and non-human primates.

    “Together with an mRNA sequence against the CMV glycoprotein gB, this multiple-antigenic mRNA vaccine induced potent and durable neutralizing antibody titers in immunized mice and non-human primates [24].”

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.
