  5. Costs and no. of persons per year

  6. Probability of going from onestate to anotherwithout vaccine

  7. Probability of going from onestate to anotherwith the vaccine. 70% reduction of cases

  8. Markov Models • Comparison of 2 Markov models • One without vaccine • One with vaccine

  9. CostEffectiveness Ratio Cost new – Costexisting Effect new – Effectexisting (1325+3500) – 3826 = 3700 kr./QALY 39,18 – 38,91

  10. Conclusion • Is it costeffective to vaccinateyounggirlsagainst HPV to preventcervical cancer? Yes • Wegain 0,27 QALY’s at the cost of 999 kr
