Abstract
Background: Meningococcal meningitis occurs globally and the predominant serogroups vary by geographic region.Vaccines against serogroups A, B, C, Y and W-135 are available in Canada.Objective: To provide guidance to health care professionals for the prevention of invasive meningococcal disease in international travellers from Canada. Methods: This Statement was developed by the Committee to Advise on Tropical Medicine and Travel (CATMAT) to compliment the Canadian Immunization Guide.It considers the need for protection and the potential for adverse effects of vaccination.Results: Meningococcal vaccine recommendations vary by traveller characteristics and travel destination.Meningococcal meningitis occurs globally and the predominant serogroup varies by geographic region.Areas of particular risk are the "meningitis belt" in Sub-Saharan Africa, Saudi Arabia during the Hajj and Umrah pilgrimages and places with current epidemics or heightened disease activity.For healthy travellers see the Canadian Immunization Guide.Quadrivalent vaccine should be given to individuals at increased risk for invasive meningococcal disease due to medical conditions with booster doses every five years.Meningococcal B vaccine should be considered. Conclusion:Vaccination is the most effective measure for preventing invasive meningococcal disease.The Government of Canada's travel health notices identify areas of new and recent meningococcal activity and are updated regularly. PreambleThe Committee to Advise on Tropical Medicine and Travel (CATMAT) provides the Public Health Agency of Canada with ongoing and timely medical, scientific, and public health advice relating to tropical infectious disease and health risks associated with international travel.The Agency acknowledges that the advice and recommendations set out in this statement are based upon the best current available scientific knowledge and medical practices and is disseminating this document for information purposes to both travellers and the medical community caring for travellers.Persons administering or using drugs, vaccines, or other products should also be aware of the contents of the product monograph(s) or other similarly approved standards or instructions for use.Recommendations for use and other information set out herein may differ from that set out in the product monograph(s) or other similarly approved standards or instructions for use by the licensed manufacturer(s).Manufacturers have sought approval and provided evidence as to the safety and efficacy of their products only when used in accordance with the product monographs or other similarly approved standards or instructions for use.

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.
