Should Varicella Vaccination Be Included in the National Childhood Vaccination Program?
Bibliographic record
Abstract
The purpose of vaccination is firstly to protect individuals from infectious diseases and secondly to control, eliminate, and if possible, eradicate diseases. Vaccination is the most effective, safe and economic healthcare intervention. Chickenpox is known as a self-limited disease usually occurring in childhood. However, it may cause serious complications and mortality with increasing age. The most common complications are secondary bacterial infections, pneumonia, arthritis, osteomyelitis, cerebellar ataxia, meningitis, meningoencephalitis, and vasculopathy. Since 1995, varicella vaccination has been recommended for routine use in the United States of America (USA), and a dramatic decrease (approximately 75%) in the incidence of the disease was detected. A reduction in hospitalizations by 75-80% was also reported. Varicella-related deaths decreased by 75-92% in children and by 74% in adults. Although varicella vaccination has been included in childhood vaccination programs in Australia, Canada, Germany, Greece, Qatar, Republic of Korea, Saudi Arabia, Taiwan, USA, Uruguay, and Lithuania, and in some parts of Italy and Spain, it has not yet been included in the childhood vaccination program in our country. In this report, views about inclusion of the varicella vaccination into the national childhood vaccination program are discussed together with various seroepidemiologic data and a cost analysis.

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.
