New 30-valent M protein-based vaccine evokes cross-opsonic antibodies against non-vaccine serotypes of group A streptococci
Open accessAbstract
Our previous studies have shown that recombinant multivalent vaccines containing amino-terminal M protein fragments from as many as 26 different serotypes of group A streptococci (GAS) evoked opsonic antibodies in animals and humans. In the present study, we constructed a new 30-valent vaccine containing M protein peptides from GAS serotypes prevalent in North America and Europe. The vaccine was immunogenic in rabbits and evoked bactericidal antibodies against all 30 vaccine serotypes of GAS. In addition, the vaccine antisera also contained significant levels of bactericidal antibodies against 24 of 40 non-vaccine serotypes of GAS. These results indicate that the potential efficacy of the new multivalent vaccine may be greater than predicted based on the "type-specific" M peptides represented.

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.
