The author reported the base-case variables used in the model as follows:
influenza illness rate, 5% (range: 5 - 15);
work absenteeism, 2 days per illness episode (range: 0.75 - 4);
reduced work effectiveness per illness episode, 0.7 days (range: 0.5 - 0.9);
reduced work effectiveness level, 50% (range: 30 - 70);
number of health care provider visits per illness episode, 0.45 (range: 0.25 - 0.65);
hospitalisation rate for influenza complications, 4/10,000 (range: 1/10,000 - 7/10,000);
death rate, 1/100,000 (range: 0.5/100,000 - 2/100,000);
work absenteeism for vaccination 0.5 hours per vaccination (range: 0.25 - 0.75);
likelihood of work loss for vaccination, 0.5 (range: 0 - 1);
work absenteeism for potential side effects due to vaccination, 10 days per 1000 (range: 0 - 20);
number of health care provider visits for potential side effects, 5 per 1000 (range: 0 - 10);
Guillain-Barre syndrome rate, 1 per 1 million persons (range: 0.5 - 2);
vaccine effectiveness in year with good match, 75% (range: 60 - 90);
vaccine effectiveness in year with poor match, 35% (range: 0 - 50); and
likelihood of good vaccine match, 80% (range: 72 - 85).
