Polyvalent mRNA vaccine targeting outer surface protein C affords multi-strain protection against Lyme disease
Bibliographic record
Abstract
There is currently no Lyme disease (LD) vaccine available for use in humans. Outer surface protein C (OspC) of the causative agent, Borrelia burgdorferi, is a promising LD vaccine target. However, the extensive genetic variation of OspC poses a challenge in affording broad protection. Here, we developed a monovalent mRNA vaccine encoding OspC type A and a polyvalent vaccine encoding OspC types A, C, I, K, and N. The monovalent vaccine conferred complete protection against homologous challenge in mice, inducing functional OspC-specific antibodies and CD4⁺ T cell responses. The polyvalent formulation elicited antibodies to all encoded OspC types and protected against strains expressing OspC types A, I, and K, but not C or N. Increasing the dose enhanced protection against the OspC type C strain. This study is the first demonstration of an effective OspC-targeted mRNA vaccine and supports the development of OspC-based vaccines for broad LD prevention.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
