Las vacunas conjugadas contra la enfermedad meningococica causadas por los serogrupos A, C, W-135, Y
Bibliographic record
Abstract
Review the current evidence on available and candidate quadrivalent meningococcal conjugate vaccines. Methods: A comprehensive overview of data on the currently available A-C-W135-Y meningococcal vaccine and the results of late stage development of novel quadrivalent candidate vaccines were reviewed. Conclusions: Licensure of highly effective meningococcal C conjugate vaccines represented an enormous progress in the possibility of controlling meningococcal C disease. The unpredictable changing serogroup epidemiology of meningococcal disease emphasizes the need of developing combination conjugate vaccines, containing more than one meningococcal polysaccharide, to broaden protection against the disease. A quadrivalent meningococcal vaccine (A-C-W135-Y) conjugated to diphtheria toxoid is available only in United States and Canada for use in persons 2-55 years of age. However, in infants (the age group with the highest incidence rates of disease) the vaccine proved to be not immunogenic and is therefore not licensed for use in children younger than 2 years.A novel tetravalent meningococcal vaccine (A-C-W135-Y) conjugated to a non-toxic diphtheria mutant toxin (CRM-197) is being evaluated in Phase III trials and has demonstrated to be immunogenic and well tolerated in all age groups, including infants, representing, at last, a real possibility of a broader protection against meningococcal disease.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
