BNT162b vaccines protect rhesus macaques from SARS-CoV-2

Open access

Abstract

A safe and effective vaccine against COVID-19 is urgently needed in quantities that are sufficient to immunize large populations. Here we report the preclinical development of two vaccine candidates (BNT162b1 and BNT162b2) that contain nucleoside-modified messenger RNA that encodes immunogens derived from the spike glycoprotein (S) of SARS-CoV-2, formulated in lipid nanoparticles. BNT162b1 encodes a soluble, secreted trimerized receptor-binding domain (known as the RBD-foldon). BNT162b2 encodes the full-length transmembrane S glycoprotein, locked in its prefusion conformation by the substitution of two residues with proline (S(K986P/V987P); hereafter, S(P2) (also known as P2 S)). The flexibly tethered RBDs of the RBD-foldon bind to human ACE2 with high avidity. Approximately 20% of the S(P2) trimers are in the two-RBD 'down', one-RBD 'up' state. In mice, one intramuscular dose of either candidate vaccine elicits a dose-dependent antibody response with high virus-entry inhibition titres and strong T-helper-1 CD4+ and IFNγ+CD8+ T cell responses. Prime-boost vaccination of rhesus macaques (Macaca mulatta) with the BNT162b candidates elicits SARS-CoV-2-neutralizing geometric mean titres that are 8.2-18.2× that of a panel of SARS-CoV-2-convalescent human sera. The vaccine candidates protect macaques against challenge with SARS-CoV-2; in particular, BNT162b2 protects the lower respiratory tract against the presence of viral RNA and shows no evidence of disease enhancement. Both candidates are being evaluated in phase I trials in Germany and the USA 1-3, and BNT162b2 is being evaluated in an ongoing global phase II/III trial (NCT04380701 and NCT04368728).

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • BNT162b2 was chosen as the pivotal candidate based on all data from the two phase-I/II trials and non-human primate challenge studies.

    “BNT162b2 was selected as pivotal candidate on the basis of the totality of data obtained in the two phase-I/II trials and challenge studies in non-human primates 2,18 .”

    From BNT162b2 vaccine induces neutralizing antibodies and poly-specific T cells in humans (2021) · cites this paper as [18]

    The Discussion (page not available) says BNT162b2 was selected for further clinical testing largely because it was better tolerated than BNT162b1 while showing comparable immunogenicity in clinical trials, and because its full-length spike offered broader T-cell epitopes. The paper reports macaque challenge studies, but does not say their results were a basis for that selection or characterize the decision as based on the totality of data from two phase-I/II trials.

  • BNT162b2 encodes the full-length SARS-CoV-2 spike protein stabilized in its prefusion conformation.

    “BNT162b2 encodes full-length SARS-CoV-2 S stabilized in the prefusion conformation 18 .”
  • Neutralizing antibody titres induced by CV2CoV in this study appear similar to those reported for other mRNA vaccines in macaques.

    “The neutralizing antibody titres induced by CV2CoV in this study also appear to be similar to those reported for other mRNA vaccines in macaques27,28.”
  • Neutralizing antibody titres induced by BNT162b2 in our study were comparable to those reported for BNT162b2 in a prior study.

    “Moreover, the neutralizing antibody titres induced by BNT162b2 in our study (Fig. 2e) were comparable to those reported for BNT162b2 in a prior study28.”
  • In preclinical studies, one intramuscular injection of BNT162b1 or BNT162b2 was sufficient to elicit an inhibitory antibody response with high titers as well as CD4+ helper and CD8+ cytotoxic T cell responses.

    “In preclinical studies, one i.m. injection of BNT162b1 or BNT162b2 was sufficient to elicit an inhibitory antibody response with high titers as well as CD4+ helper and CD8+ cytotoxic T cell responses.107”

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.
