Abstract

Severe acute respiratory syndrome (SARS) caused by a newly identified coronavirus (SARS-CoV) remains a threat to cause epidemics as evidenced by recent sporadic cases in China. In this communication, we evaluated the efficacy and safety of two SARS vaccine candidates based on the recombinant modified vaccinia Ankara (MVA) expressing SARS-CoV spike or nucleocapsid proteins in ferrets. No clinical signs were observed in all the ferrets challenged with SARS-CoV. On the other hand, vaccination did not prevent SARS-CoV infection in ferrets. In contrast, immunized ferrets (particularly those immunized with rMVA-spike) exhibited significantly stronger inflammatory responses and focal necrosis in liver tissue after SARS-CoV challenge than control animals. Thus, our data suggest that enhanced hepatitis is linked to vaccination with rMVA expressing SARS-CoV antigens.

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

  • In animal models of other coronaviruses and prior inactivated RSV or measles vaccines, VAERD is usually linked to Th2-biased CD4+ responses with elevated IL-4, IL-5, or IL-13.

    “In animal models of infections with other coronaviruses and for previous whole-cell inactivated vaccines developed for respiratory syncytial virus and measles virus, VAERD has usually been associated with the development of T helper 2 cell (TH2 cell)-biased CD4+ T cell responses, with significantly increased levels of interleukin-4 (IL-4), IL-5 and/or IL-13 (refs12,126,165–174).”

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.
