Bulletin, In Japan, Preventive Vaccinations Act was established in 1948 and it was revised several times until today. Currently, people's concern is turned to the side reaction or health impairment of vaccination from the threat of infection, because critical infection diseases have been decreased. The purpose of this study was to investigate parent's consciousness and anxieties of vaccination, and to consider good situation of vaccination. Questionnaires about vaccination of children were distributed to parents at kindergarten in 2010. Over 90% of 161 responded have inoculated combined vaccination for Diphtheria, Pertussis and Tetanus, BCG and Poliomyelitis at the time of standard inoculation age, however, Measles-rubella vaccine was low inoculation rate. No significant difference was noted in the rate of inoculation between the parents with a job and without a job. Many of them got vaccinated at their family doctor's clinic, and approximately 20% of them experienced light side reaction like rubefaction or swelling. It is important to explain about possibility of the side reaction for decreasing parent's anxieties against vaccination. Of these 161, 15 children could not inoculate following the standard vaccination schedule, because it was difficult for parents to have a day off for taking their child to clinic for vaccination. It takes for long time to approve of new vaccine in Japan, compared with the other foreign advanced countries. These were the one of reasons for epidemic outbreak of Pandemic influenza A（H1N1）in Japan. Also, the vaccination schedule of Japan is tight, therefore it is necessary to improve them. One hundred twenty one were parents who have recognition of the need for vaccination for living in a group like a kindergarten. Considering the region gap and education efforts about vaccination are needed for parents to raise inoculation rate and to prevent their children from critical infection diseases.
