The total cost of the school-based programme was $13.51.
The total cost of the managed care organisation and provider approach was $18.00.
The risk of contracting hepatitis B virus for those not immunised is 4.16%. Multiplying this by the health care costs of treating diseases likely to be contracted by those infected with hepatitis B yields a potential cost of $33.65 million for 6th-grade students in Kansas City, assuming an 8% uptake of immunisation.
With the 82% immunisation uptake from the programme, this figure was reduced to $9.46 million.
