Cost benefit ratio

A cost-benefit study of vaccination compares the costs of vaccination to the costs of no vaccination. Direct costs include medical costs, while indirect costs include costs of absenteeism from work or school. Several studies show reductions in absenteeism and influenza-like illness of 35-60% with vaccination, leading to direct savings per year of $1177-2236 per vaccinated person. Vaccination reduces costs from prevented sickness and is therefore considered a cost-effective preventive tool against communicable diseases.
