[Economical effect of vaccine].

In Japan, some vaccines are provided partially or only at citizens' own expense, while France and Germany publicly cover immunization on the basis of findings in economical effect on VPD (vaccine preventable disease). Such study recently conducted in Japan by the government was reported. According to cost comparative analysis, pneumococcal conjugate vaccine (PCV) for both children and adults, mumps, and varicella were found to have certain economical effect, while cervical cancer, hepatitis B, and Hib virus were not. Cost effectiveness analysis found PCV for adults, pertussis, mumps, and cervical cancer to have favorable effect, while not for Hib and PCV for children. These results offer some perspective, but cautious interpretation may be necessary since premises differ among analyses.
