Summary of recommendations for the prevention of viral hepatitis during travel
Bibliographic record
Abstract
Viral hepatitis is considered the most common travel-related, vaccine-preventable disease. All non-immune travellers to developing countries should consider vaccination with inactivated Hepatitis A (HA) virus vaccine and recombinant Hepatitis B (HB) virus vaccine. Inactivated HA and recombinant HB vaccines are safe, have few side effects and are effective in providing long-lasting protection. All monovalent HA and HB vaccines available for use within Canada are equally effective, and each can be used interchangeably. HA Ig (immune globulin) should be used to prevent HA only in those for whom active HA vaccines are contraindicated, in immunocompromised individuals who may not respond adequately to the active vaccines or in infants less than one year of age. All travellers should practise routine protective measures when abroad. HB virus carriers travelling to Hepatitis D virus-endemic countries should be particularly vigilant in avoiding high-risk activities such as skin piercing and unsafe sexual practices.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
