Abstract

Building Better Vaccines: Vaccines are one of the most effective tools to protect against infectious diseases. Unfortunately, vaccines for diseases with the highest global health burdens, such as HIV, malaria, and tuberculosis, are not yet available. Koff et al. (p. 1064 ) review the latest advances in vaccine development and why these particular diseases remain such a challenge. Respiratory syncytial virus (RSV) is a serious cause of morbidity and mortality in infants and young children worldwide. Although a prophylactic antibody is available for children at high risk, a vaccine is much needed. As a potential step toward this goal, McLellan et al. (p. 1113 , published online 25 April) solved the cocrystal structure of a neutralizing antibody (D25) bound to the prefusion F protein of RSV. Knowledge of the structure of the prefusion protein should help to guide vaccine design and the development of additional therapeutics.

  • Newfound structural insights into F protein conformation have revealed that vaccinating against the prefusion conformation elicits superior neutralizing antibody response.

    “Although some candidates have failed clinical trials owing to insufficient neutralizing antibody titres174, newfound structural insights into F protein conformation have revealed that vaccinating against the prefusion conformation elicits superior neutralizing antibody response175–178.”
  • Antibodies 5C4, AM22, and D25 are substantially more potent than palivizumab and target antigenic site Ø.

    “Antibodies such as 5C4 (7), AM22, and D25 (11, 12) are substantially more potent than palivizumab and target antigenic site Ø, a metastable site located at the membrane-distal apex of the prefusion RSV F trimer (7).”
  • The β-carbons of serine residues 155 and 290 are 4.4 Å apart in the D25-bound RSV F structure and 124.2 Å apart in the postfusion structure.

    “The β-carbons of serine residues 155 and 290 are 4.4 Å apart in the D25-bound RSV F structure (7) and 124.2 Å apart in the postfusion structure (5) (Fig. 1 and fig. S2).”
  • Antigenic site Ø is a metastable site specific to the prefusion state of RSV F and is targeted by extremely potent RSV-neutralizing antibodies.

    “focused on antigenic site Ø, a metastable site specific to the prefusion state of the RSV fusion (F) glycoprotein, as this site is targeted by extremely potent RSV-neutralizing antibodies.”
  • The steep slope of this correlation likely reflects the substantially higher neutralization potency observed for prefusion-specific antibodies that target antigenic site Ø.

    “Notably, the steep slope of this correlation likely reflects the substantially higher neutralization potency observed for prefusion-specific antibodies that target antigenic site Ø (7, 38).”

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.
