Enhancing immune responses using suicidal DNA vaccines

Abstract

We describe a DNA vaccine strategy that allows antigens to be produced in vivo in the context of an alphaviral replicon. Mice immunized with such vectors developed humoral and cellular immune responses at higher levels than mice that received a conventional DNA vaccine vector. Immunized animals acquired protective immunity to lethal influenza challenge. Compared with traditional DNA vaccine strategies in which vectors are persistent and the expression constitutive, the expression mediated by the alphaviral vector was transient and lytic. As a result, biosafety risks such as chromosomal integration, and the induction of immunological tolerance, could be circumvented.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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.
