Cost effectiveness and cost benefit of a potential chickenpox vaccination strategy in Slovakia have been evaluated. As a base for comparison with potential vaccination strategy, direct and indirect costs of chickenpox incidence in Slovakia in 1996 were evaluated, using the EPIS data (Epidemiological Information System in Slovak Republic), and official annual analyse of epidemiological situation in Slovakia. According to their estimates, the authors consider the potential chickenpox vaccination as highly cost effective. The results of their analysis show that as the saved costs mostly indirect costs participate. With respect to the prevailing social impact of chickenpox also the funding of the future chickenpox vaccination is supposed to be shared by social insurance system.
