Abstract

This paper attempts to summarize current knowledge about immune responses to vaccines that correlate with protection. Although the immune system is redundant, almost all current vaccines work through antibodies in serum or on mucosa that block infection or bacteremia/viremia and thus provide a correlate of protection. The functional characteristics of antibodies, as well as quantity, are important. Antibody may be highly correlated with protection or synergistic with other functions. Immune memory is a critical correlate: effector memory for short-incubation diseases and central memory for long-incubation diseases. Cellular immunity acts to kill or suppress intracellular pathogens and may also synergize with antibody. For some vaccines, we have no true correlates, but only useful surrogates, for an unknown protective response.

Claims other papers make about this one

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

  • Neutralizing antibodies correlate with protection against COVID-19.

    “Antibodies are critical for defence against viruses and nAbs have been shown to correlate with protection against COVID-1918,19 to inform immunization schedules20.”
  • 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.”
  • Neutralizing antibodies are sufficient to prevent dissemination of many diseases within populations.

    “It has been demonstrated that neutralizing antibodies are sufficient to prevent dissemination of many diseases within populations (Plotkin, 2010).”
  • Neutralizing antibody levels correlate with protection against many viruses including SARS-CoV-2 in humans, and high neutralizing titers are particularly important for protection against novel circulating SARS-CoV-2 variants.

    “The role of neutralizing antibodies is in particular crucial because neutralizing antibody levels correlate with protection against many viruses including SARS-CoV-2 in humans [35,36]; recent data suggest that high neutralizing titers are particularly important for protection against novel circulating SARS-CoV-2 variants conferring immune escape [37][38][39].”

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.
