An economic evaluation was performed of universal acellular pertussis vaccination in Italy, where until recently the overall coverage of pertussis vaccination was estimated at 50%. Over the last two years coverage seems to have increased rapidly. By means of a mathematical simulation model, the consequences of pertussis vaccination in terms of both health effects and economic costs were calculated for a single birth cohort followed for 6 years.

We analyzed the cost-effectiveness of hepatitis A vaccination regimens using a mathematical simulation model. Passive immunization and two active vaccination strategies (with and without prior screening) were compared with "doing nothing." Hepatitis A antibodies were determined in 2,325 Dutch marines; other input data were retrieved from published and unpublished sources.

Unlabelled: Acellular pertussis vaccines are less reactogenic than whole cell pertussis vaccines, but they are also more expensive. Based on simulation models, we compared the costs and effects of three alternative pertussis vaccination strategies in German children to "no prevention": (1) vaccination with whole-cell vaccine at 45% coverage (vaccine efficacy 90%), (2) vaccination with acellular vaccine at 45% coverage (vaccine efficacy 85%), and (3) vaccination with acellular vaccine at 90% coverage. In the two low coverage scenarios expected annual savings in direct medical costs through prevention of disease were larger for whole-cell than for acellular vaccination (252 vs 216 million DM, respectively).

This study assessed the costs and benefits of introducing routine varicella vaccination to healthy children in Germany. Three vaccination strategies were compared with that of no prevention: vaccination of all 15-month-old children: vaccination of susceptible 12-year-olds (adolescent); and a combination of strategies (children including catch-up). From a purely economic viewpoint, the adeolescent strategy was optimal: It was the only one that resulted in net direct cost savings.

Background: The strategies for the management of onychomycosis have changed since the availability of the newer generation of antifungal agents, particularly, itraconazole and terbinafine. Itraconazole (1-week pulse) therapy may have higher efficacy and an improved adverse-effects profile compared to the continuous therapy regimen.

Objective: We performed a pharmacoeconomic evaluation of the most commonly used treatments in Germany for toenail onychomycosis from a health care payer perspective.
