Efficiency of the incorporation of the hepatitis A vaccine as a combined A+B vaccine to the hepatitis B vaccination programme of preadolescents in schools.
In 1998, the Department of Health of Catalonia (Spain) began universal vaccination of preadolescents against hepatitis A by replacing the simple hepatitis B vaccine with a combined hepatitis A+B vaccine. Economic analyses were made of the two alternative strategies: to continue with the simple hepatitis B vaccination or to replace the simple vaccine with a combined hepatitis A+B vaccine. The analysis was made from the societal perspective and the time horizon considered was 25 years. In the base case, (estimated annual hepatitis A incidence of 15 per 100,000 and incremental price of the hepatitis A+B vaccine over the simple hepatitis B vaccine of 1.98) the net present value of the programme was positive (+533,708) and the benefit-cost ratio was 2.58. If the estimated disease incidence were reduced by half, the programme would still be efficient.
